. New trout strain is resisting disease Coloradoan news services George Schisler, a Colorado Division of Wildlife aquatic research scientist, holds a Hofer strain of rainbow trout that the agency said is resistant to whirling disease and has reproduced naturally in the state. For the first time since whirling disease decimated most naturally reproducing rainbow trout populations throughout Colorado more than a decade ago, new strains of rainbows have reproduced naturally in the Gunnison River and in ponds located along the Frying Pan River near Basalt. Colorado Division of Wildlife biologists are hopeful that the successful natural reproduction will lead to re-establishing wild, self-sustaining rainbow trout populations in Colorado where whirling disease has precluded wild rainbow trout recovery efforts. The fish, a cross of the Hofer rainbow trout and other rainbow strains that are used for stocking, appear to be resistant to whirling disease. The fish were "young of the year'' and hatched in May 2007. They were captured in October when DOW aquatic researchers conducted electro-fishing operations in the two areas. "They were plump, colorful fish, they looked good,'' said Barry Nehring, an aquatic researcher for the DOW in Montrose who has been working on whirling disease since 1994. "This is indicative that we've had successful reproduction.'' Several of the fish were sent for genetic testing to a laboratory in Boulder that verified the fish were offspring of Hofer-cross rainbows stocked in the river and the ponds in 2004 and 2005. Hofer cross fingerlings were also stocked in the upper Colorado River near Kremmling in 2006 but researchers did not find any young fish there in 2007. Biologists said that fish grow more slowly in the Colorado River because the water is very cold. Consequently, researchers speculate that Hofer crosses stocked there might not yet have reached sexual maturity. They'll look for young fish again this fall. The Gunnison River is lower in elevation, water temperatures are warmer and it is renowned for producing large trout. Brown trout - which are resistant to whirling disease - thrive in the river. The ponds on the Frying Pan River also provide relatively warm water. George Schisler, a DOW aquatic research scientist, is hopeful that the next positive milestone will come late this year. Judging from research conducted on the Hofer strain, scientists are confident that the fish will survive and continue to reproduce. Whirling disease is caused by a microscopic parasite that passes through the fish’s skin. The organism attacks the cartilage of young fish and distorts the spine. The affected fish move in a whirling motion, basically swimming in circles when excited or when trying to escape predation. This type of behavior greatly reduces their ability to survive in the wild. The disease was found in Colorado in the mid-1990s and it devastated most wild rainbow trout populations throughout the state. During a whirling disease seminar in 2002 in Denver, a German scientist delivered a research report about a rainbow strain that was resistant to whirling disease. The Hofer rainbow trout was raised in a German hatchery. In 2003, DOW researchers worked with the University of California-Davis to import the eggs and start a brood stock at the Fish Research Hatchery near Fort Collins. The fish were exposed to the disease and then dissected to see how many parasite spores had developed. Schisler said researchers were stunned by what they saw. Spore counts in Colorado River Rainbows — which have been used for stocking by the DOW for years — exposed to the disease could reach 4 million per fish. The highest count in the Hofers reached about 3,000 and did not affect the fish. DOW aquatics staff then started crossing the Hofers with existing rainbow stock and conducting more tests. Not only were the new strains of fish resistant to the disease, they also grew faster than traditional stocker strains. Hofers grew to catchable size — about 10 inches — in about 14 months, four months faster than the other rainbow trout strains. In 2004, fingerlings of the new cross strains were first released into the Gunnison River. They were first released into the Frying Pan River ponds in 2005 and into the Colorado River in 2006. Some catchable-size crosses were also stocked in two reservoirs near Berthoud in the spring of 2006. The fish continued to grow in the reservoirs and anglers were successful in catching them. “No other state has conducted more research into identifying real solutions to the whirling disease problem,’’ said Mark Jones, the DOW’s aquatic research leader. “We could tell this was a good thing from the start.’’ Based on the extensive research, the DOW hatcheries are expanding production of the various crosses. This year, more than 1 million sub-catchable and catchable fish of the Hofer crosses are planned to be stocked in lakes and rivers throughout Colorado. Research to examine the resistance of the Hofer crosses to whirling disease and their ability to survive in the wild is ongoing.

Winter a lure on the Bay Henry Bury Bellville Intelligencer A father and son from St. Catharines did plenty of "jigging" in Belleville over the weekend. Dick Vanstone, his son, Darren, and a good friend, Bob Buttery, ice fished on the Bay of Quinte Saturday morning and evening as well as Sunday morning. "We were out Saturday morning for three hours and it was slow. We had no bites for walleye," said the 65-year-old Dick Vanstone, a retired Sears Canada employee. "I don't think the east wind helped." The trio did manage to catch a few perch about a mile out from the Herchimer Avenue boat launch. But a week earlier, the father-son duo also did some ice fishing on the bay and they caught three walleye - weighing from three to five pounds each - between them. "Those were our only two times here this winter," he said. Other anglers interviewed by The Intelligencer reported plenty of good fishing trips this winter on various sections of the bay. For Vanstone, though, he said it's almost "embarrassing" not catching any walleye this past weekend - anglers are allowed to catch four walleye per day. "We usually catch walleye every time we're out in the summer," he said. Vanstone and his son have a summer trailer in Deseronto and they do a lot of fishing from when the walleye season opens in the spring to about the end of November. They often enter various summer fishing tournaments. They also visit Belleville a few times over the winter to do some ice fishing. "It's been slow the past couple of weeks," Vanstone said. "The ice conditions are not good. The thickness is good but there is too much snow and slush." Darren Vanstone, 42, said ice fishing on the Bay of Quinte is "better than sitting at home." Besides, he added, there is no pickerel fishing where they live. "So we come here because it's supposed to be the walleye capital of Ontario," he said with a smile. The angling trio towed an ATV with their van. Vanstone said there was no other way to get out on the bay because of the heavy slush on the ice. After arriving at their spot, each man drilled an eight-inch hole and sat on five-gallon pails for the next three hours. "We're just jigging spoons over the hole," said Vanstone, adding they were tipping the spoon with minnows. "It's just nice to be out for a couple of hours. But it would be even nice to catch some walleye," he said. For Bob Buttery, this was the 71-year-old's first ice fishing trip in Belleville this winter. "I've enjoyed the fishing but would have preferred a few more bites, not nibbles," he said. Justin Singh, 23, of Toronto, braved the elements Sunday afternoon to try his luck about 100 metres out from the Herchimer Avenue boat launch. "I didn't catch anything except frostbite," he shrugged while the wind whipped across the frozen bay. Singh normally ice fishes near the George Street boat launch "but the ice there wasn't safe enough. So I came here for a couple of hours ... I only get one day a week so I fish here and try and make the best of it." Belleville's Gene Frederick fished off Big Island near Demorestville and said an angler just yards from him managed to snag a 12.32 pound, 32-inch walleye Saturday morning. "There was lots of fish being caught this morning ... And me, nothing but heartache today," he said while picking up some more bait at Skevy's fish and bait store on Dundas Street East. Frederick said he's managed to catch several pickerel this winter. "The fishing has been good, not excellent. And not as good as last year. But that's only one man's opinion," he said. Paul Cotton, also of Belleville, has only been ice fishing for the past couple of winters. "I have caught a couple of walleye this winter," said the novice angler. "And I have been out quite a few times." Cotton said he has a pop-up ice hut and his favourite spot is near Point Anne. "I've heard there are lots of fish in the bay but you really have to be careful because the ice is thin in a lot of places," he said. As owner of Skevy's bait store, Ron Skevington has heard many fish stories this winter. "We've had days that have been phenomenal and days where it's just not good at all," he said. "And that's because of the weather pattern being up and down. The barometer is high one day and low the next. This warm/cold cycle is confusing the fish." Skevington said the unusual winter weather has plagued anglers, and that comment is borne out by the few ice huts dotting the frozen bay. "The fish are there but the problem is that with climate change, we're not getting the thick ice like we used to. We still have open water under the bay bridge, for example, and anglers have to be careful where they drop their line," he said. Despite the unpredictable weather, Skevington said he's received "very good" comments about the ice fishing on the bay. "The fish is good for walleye for most people, but there are some who come in skunked, like me, because I'm always here," he said with a laugh. He added more anglers are reported catching big jumbo perch measuring about 12 inches "and that's unusual for the Bay of Quinte." Skevington said this region's reputation for walleye still attracts a lot of anglers from well outside the Quinte area, and he arranges accommodation and where to fish for visitors. "I had a group of five people from Timmins who drove non-stop to get here Friday night so that they could fish all weekend," he said. Later this month, he will welcome a group from Wisconsin, some of whom work for Walleye Insider Magazine, as they test the Bay of Quinte. "I also have another guy from Germany coming the last weekend in February," he said. The ice fishing season ends Feb. 29 and ice huts have to be off the Bay of Quinte.

Students spread message on protecting Lake Simcoe; Georgian College group talks with ice fishermen Kelly McShane Barrie Examiner Georgian College students took to the ice this weekend to raise awareness of the issues affecting the health of Lake Simcoe. "We want people who are enjoying the lake to be aware of what's at risk here if we don't get a protection act in place for Lake Simcoe," said Claire Malcomson, co-ordinator of Campaign Lake Simcoe and a member of Environmental Defence. High levels of phosphorus, found in detergents and fertilizers, is one of the main issue affecting Lake Simcoe, the group says. Phosphorus artificially increases weed and algae growth. When the growth decomposes, it chokes off the lake's oxygen, making it difficult for cold-water fish to breathe. Members of GEAR, Georgian Students for Environmental Awareness and Research, went "hut to hut" yesterday in glacial temperatures and intense wind to discuss the issue of phosphorus and the proposal of a protection act for Lake Simcoe with ice fishermen utilizing the lake. "With the amount of waste that goes into this lake, they will never be able to purify it in a million years. What's been done is irreversible, but we need to stop it before it gets worse," said John Top of Owen Sound, one of the fisherman approached by GEAR members. GEAR and Environmental Defence have had great success in the last year in bringing awareness to the public and receiving recognition for their cause from politicians. When the campaign to protect the lake was mentioned in Premier Dalton McGuinty's Throne Speech this past November, the group knew they had made headway. Campaign Lake Simcoe expects there will be a Lake Simcoe Protection Act in place by the end of the year, but Malcomson, whose family has owned a cottage on the lake for more than 115 years, hopes it will be underway by the summer. Carlo Baldassarra was one of many fishermen approached by GEAR this weekend who takes the health of the lake seriously, and who has personally pitched in to help keep the area's waterways clean. "We work closely with the Ontario Steelheaders and volunteer with cleaning streams and lakes in the spring, summer and fall," Baldassarra said of he and his friends. Jeremy Fromanger, professor of engineering technology at Georgian, founded GEAR with a group of friends in 2004, and is an active influence within the group. Fromanger came out to help with this weekend's crusade, and is thrilled with the support his grassroots group has received over the years. GEAR member Katie Sage, 22, a fine arts student at Georgian, ventured onto the lake's coarse terrain both Saturday and Sunday to pass out pamphlets and discuss the plight of the lake. "It is a really humbling experience," Sage said of speaking to the fishermen in their own element. Sage has been involved in environmental issues since childhood, and is enthusiastic about being recruited as a volunteer by GEAR.

Truck goes trough ice on Nipissing Kate Adams BayToday Saturday, February 09, 2008 OPP have issued a warning that the public should use extreme caution on Lake Nipissing after a truck went through the ice this afternoon. The vehicle was traveling along Lake Nipissing approximately half a mile off shore across from the sewage plant on Saturday afternoon when it hit open water and began to submerge. “As we were heading out across the ice I was just checking where the door handle and things were … when I heard a loud crack and the front of the truck just started going in,” passenger Melanie Rowley, tells BayToday. “I rolled down that window and tried the door handle, but the door was blocked by the ice, so I crawled out onto the ice, and then yelled at Nicole to do the same … crawl out on my side.” Rowley, who is home in the Bay from Calgary to visit family and friends, says there were no injuries but both she and the driver are shaken up by the ordeal. Emergency personnel responded and have cordoned of the area with pylons where the truck went in and Rowley says that the truck will be lifted out of the lake Sunday.

Discovering joys of two-handed casting By Fred Lebrun - ALBANY TIMES UNION 02/10/08 6:43 AM In the steelhead and western salmon fly-fishing world, two-handed rods of various kinds are all the rage. Out West, where the rivers are big and the winds are perpetual, that’s been the case for a while. Spey rods and two-handed casting have taken over the western steelhead fishing culture. Here in the East, we have been much slower to make the leap in that direction. On New York’s famed Salmon River in Pulaski, while the occasional spey rod shows up, it’s rare. That’s about to change. Mark June 21 on your calendar. Not a particularly auspicious time to be plodding along the banks of the Salmon River, though there might be a few early summer steelhead coming in and a few more landlocked salmon. Down in the lower pools, certainly a ton of smallmouth and football-shaped brown trout will be there but not the great runs of Chinook and kings and steelhead. Those come later. So this makes the date and the occasion full-focused on casting — and learning all about spey and two-handed rods — from some of the best instructors in America. It’s an amazing opportunity, and it is free. Spey Nation’s “The Experience 2008,” was concocted after a late-night Internet bulletin board chat between my colleague, Geoff Schaake, a former Alaskan fishing guide and very accomplished fisherman, and fellow enthusiast Zach Brooks, over their passion: spey and two-handed casting. What they’ve come up with is nothing short of amazing. “The Experience 2008” will be held on a 75-acre field adjacent to the Salmon River on County Route 52 in Altmar, Oswego County, beginning at 8 a.m. There’ll be a day-long barbecue, sponsored by the Oak Orchard Fly Shop, and a two-handed rod demonstration by several experts. All proceeds will be donated either as cash or equipment to the state’s Salmon River Hatchery nearby. This opportunity is boundless for spey and two-handed rod enthusiasts — and those attracted to it but inexperienced. Manufacturers’ representatives from all the biggest names will be there, as well as local guides and some of the more prominent names in the two-handed industry. Including rod designer Bob Meiser, who has created benchmark rods for Beulah and Temple Forks Outfitters in addition to his own company, the Meiser Rod Co. A West Coast guy, this will be Meiser’s first trip to the Great Lakes steelhead fishery. The range of demonstrators goes from Meiser, who will be showing off the newest technology, called switch rods, to representatives casting Beulah, CNA and Burkheimer. More about Spey Nation and this event, including various accommodations, can be gotten from http:// www.speynation.com. On Sunday, certified spey casting instructors will give formal lessons for a fee. For more information, e-mail Schaake at infotheanglersnet. com.

So what did you do with your Saturday Afternoon?
Spiel replied to irishfield's topic in General Discussion
....Sheeesh it sure would be nice to have a big work shop at my disposal. Looks like you'll be all set for Temagami Wayne. I spent my afternoon shopping at Fishing World for a few new things I wanted for tomorrows trip. I'm taking the young lads and the GF up to Simcoes east shore for some perch and whitefish action, I hope. Rented a 6 man hut and we'll get chauffeured out in the ole "bambadier". I think they'll all enjoy that. -
Wide-eyed about walleye on Lake Winnipeg CINDA CHAVICH Special to The Globe and Mail February 6, 2008 GIMLI, MAN. -- The fishing season may be over in most of Canada, but out on Lake Winnipeg, serious pickerel fishing is under way. Fishermen such as Chris Kristjanson are setting their gillnets under several feet of ice for some of the finest pickerel (also known as walleye) in the world. Canada's commercial pickerel fishery feeds the growing market for this sweet, mild fish, shipped to locales from Norway to New York. In fact, the fish that many prairie children remember catching in northern lakes has become one of the most expensive fillets in the fishmonger's case. It's a case of supply and demand: With no commercial fishery for pickerel in the United States, all of the firm white fillets that turn up in top restaurants such as Everest in Chicago are from Canadian waters. The pickerel fishery has never been better in Lake Winnipeg. "We used to go out all day and get a box of fish [80-100 pounds] and now it's 10 or 15 boxes," says Eric Goodman. "There's so much fish now." It's a mixed blessing. In midsummer, the northern reaches of this massive water body are covered in thick patches of blue-green algae, a result of phosphates, manure and fertilizers from farms as far away as Alberta. While that makes for plenty of fish food now, in the long run, the algae dies, drops to the bottom of the lake and, as it decomposes, strips oxygen from the water. It threatens a fishing tradition that has been carrying on since 1882. By 1887, 1.1 million kilograms of fish were caught in the lake, most by the Icelandic immigrants who settled here. Third- and-fourth-generation fishermen - the Kristjansons, Olsons and Goodmans - still make their livings from pickerel, pulling in about 3.2 million kilograms from the lake each year. "We started selling fish when we were kids - we'd grab the bus to Winnipeg Beach in the morning and we'd peddle fish to cottages along the lakeshore," says Paul Olson, 89, a retired fisherman who remembers going fishing with his father on dogsled. His daughter Karen still runs the family's Gimli Fish Market in Winnipeg. Today, the Gimli fishermen still head out on the ice, many in vintage 1940s and 1950s Bombardier Snowcats, from the end of November until the end of March. Which makes midwinter the best time to enjoy fresh pickerel. At the Current in Winnipeg, chef Brian Roloff serves pan-fried fillets of Manitoba pickerel in a champagne beurre blanc sauce, topped with braised leeks. At Crave Kitchen in Regina, the wild Saskatchewan walleye is quick-seared with lemon sauce. In Gimli, at the Beach Boy restaurant, you can indulge in the sweetest bits - the cheeks - ordered at the counter with fries and pop or Greek salad. Most locals, though, say they usually serve it up prairie-style - "fried in butter with mashed potatoes, creamed corn and pickled beets." Unfortunately, demand is keeping prices high. At Mariner Neptune, the Winnipeg fish wholesaler and retailer, the price in the shop is $9.99 a pound, more expensive than sole or cod, and nearly as high as Arctic char. "It's one of the most expensive fish we sell," he says, "but Costco now buys 5,000 to 7,000 pounds a week."

NEW RESEARCH EXPLAINS RELATIONSHIP BETWEEN COMMERCIAL PRICE, AMOUNT OF HARVEST, AND ALARMING DECLINE IN AMERICAN EEL February 4, 2008 Great Lakes Fishery Commission ANN ARBOR, MI—Researchers from Queen’s University have analyzed commercial American eel harvest and price data from the period 1950 to 2004 from across the range of the species to gain a better understanding of possible factors leading to the dramatic decline of the key native species. The research concluded that an increase in the value and price of the American eel, along with high abundances in the early days of commercial exploitation, heavy exploitation, and expanded and integrated markets, created a demand that contributed to a permanent reduction in the reproductive capacity of the species. This inability of the species to replenish itself subsequently led to severe declines in recruitment and population size. Scientists are interested in learning as much as possible about the American eel given that populations have undergone a major long-term decline over much of its range, quite Precipitously in the Great Lakes Basin. This research project was supported by the Great Lakes Fishery Commission, Ontario Ministry of Natural Resources, and Fisheries and Oceans Canada. Up through the 1980s, Lake Ontario, the most easterly of the Great Lakes, supported one of the largest aggregations of large, fecund female eels in North America. American eels are uniquely catadromous, spawning in the ocean and maturing in brackish and fresh water, and are one genetic, or spawning, stock. This species has an unusual life history involving larval, several juvenile, and adult life stages, and its life cycle plays out over an extraordinarily large range. Larvae, spawned in the Atlantic Ocean’s Sargasso Sea, disperse northward along the American Continental Shelf from as far north as the Maritimes to Florida and beyond. Juveniles migrate into coastal rivers and lakes along the Atlantic seaboard to develop and mature into adults, which head back to the Sargasso Sea to spawn. Eels were once so plentiful in Lake Ontario that they constituted an important part of the lake’s biodiversity. Now they are faced with imminent extirpation—the number of young eels migrating upstream through a passage facility to Lake Ontario has declined by three orders of magnitude from the peak levels of the 1980s. No single cause of the population decline has been identified, though upstream and downstream barriers to migration such as hydroelectric dams, turbine mortality, overfishing, loss of critical habitat, environmental changes in rivers and the ocean, and other factors may have played a role. This research project aimed to understand the relationship between the commercial price of eels, levels of harvest, and decline in abundances. “We analyzed harvest and landed value data dating back to the 1950s from provincial and state jurisdictions across the North American range of the eel,” said Dr. John Casselman of Queen’s University, the study’s principal investigator. “Price, deflated and standardized in terms of 1950 Canadian dollars, led to a better understanding of harvest and changing abundance. We learned that standardized price of eels increased two-to-threefold over the period, but because of reduced harvest, the value of the fishery is no greater now than in the 1950s.” “Significant deviations from synchronicity between harvest and price were first associated with high harvest at low price for emigrating silver [mature] eels in the lower St. Lawrence River in the 1950s, possibly related to lower turbine mortality prior to installation of the Moses-Saunders hydroelectric dam in the upper St. Lawrence River,” Casselman continued. “In the late 1960s and early 1970s, a disproportionately high harvest of eels initiated an unprecedented rate of regional harvest in the Gulf region of the St. Lawrence River and to a lesser extent in Newfoundland and the sea fishery in Quebec. This harvest appeared to be related to increased abundance, possibly caused by reduced elver [juvenile] immigration up the St. Lawrence River system and a backing-up downstream from Moses-Saunders dam, which created a partial obstruction—for 17 years, 1958-1973—before a ladder was installed to facilitate eel passage in 1974.” According to the research report, commercial harvest was extremely high in the late 1960s to the early 1980s in both Canada and the United States and continued into the early 1990s in Canada. Said Casselman: “During the late 1970s and early 1980s, heavy exploitation in both countries resulted in declining catch and smaller eels, with a substantial increase in price near the end of the period. These sequential declines followed heavy exploitation of the 1970s and subsequent declining recruitment in the late 1970s. If harvest in some areas was previously underestimated by either underreporting or nonreporting, recent decreases in commercial harvest would be more severe than trends suggest.” “Regulations and management did not greatly curtail harvest until the mid-to-late 1990s, well after declines had begun, and contaminants and closures were generally short-term, local, and relatively minor,” said Casselman. “The combination of increasing and high price with decreasing and low harvest in the presence of minimal regulations indicates decreased abundance of eels, since price is inversely related to abundance, confirmed in the upper St. Lawrence River and Lake Ontario, where price paid was inversely correlated with size of the harvestable stock.” Casselman concluded: “When harvest was examined in relation to price, it was apparent that a combination of high early abundance, possibly accentuated by obstruction, heavy exploitation, expanded and integrated markets, created a demand. Along with increased value and price, these major factors worked in unison to increase harvest significantly, permanently reducing reproductive capacity of the species and subsequently creating declines in recruitment and population size, most apparent at the extremities of the range.” Dr. John Casselman (Queen’s University) 613-533-6000 x 75371 Dr. Marc Gaden (Great Lakes Fishery Commission) 734-662-3209 x 14 --------------------------------------------------- The Great Lakes Fishery Commission is an international organization established by the United States and Canada through the 1954 Convention on Great Lakes Fisheries.

SCIENTISTS USE ODOUR CUES TO LURE INVASIVE ROUND GOBIES INTO TRAPS February 4, 2008 Great Lakes Fishery Commission ANN ARBOR, MI—New research conducted by scientists from the University of Windsor and the Ontario Ministry of natural resources provide initial evidence that one of the Great Lakes’ most invasive pests, the round goby, could be lured into traps by the scent of male round goby urine. Male round goby urine, it was found, contains sex steroids that serve to attract female round gobies. The research, funded by the Great Lakes Fishery Commission, could lead to management techniques aimed at reducing round goby abundance in critical habitats or limiting and possibly preventing their spread into new waterways. Round gobies were first discovered in the Great Lakes in 1990 and have since spread rapidly. In fact, the round goby is the fastest spreading vertebrate ever reported in the Great Lakes. They entered the lakes through the discharge of ballast water from oceangoing vessels. Being exotic to the ecosystem, gobies have disrupted the environment and the economy of the region. They are known to displace native fish, consume young fish and fish eggs, become over-abundant in prime habitat, and survive in areas of poor water quality. They spawn several times a year, proliferate in great numbers, and steal anglers’ bait. There is no commercial or recreational value for round gobies and fishery managers would welcome methods to control their spread. The current research built upon on the hypothesis that the reproductive male round goby releases a sex attractant to lure spawning females. Earlier studies showed that a single round goby male can lure up to 15 spawning females to one nest, so anything fishery managers can do to attract round gobies could disrupt their behavior and spawning cycles. To test the hypotheses, the researchers used a variety of odours (males, females, male urine, food) to lure round gobies to traps in flowing and still water. “Our findings showed that life-like models of male round gobies, inserted with a time-release tablet of reproductive male urine, attracted spawning female round gobies,†said Dr. Lynda Corkum, of the University of Windsor, the principal investigator of this research. “We found that combining the odour with model is more effective at luring round gobies than using food or adult gobies alone, probably because round gobies use both visual and odour cues to attract mates.†Corkum continued: “Overall, our findings show that there is potential of using reproductive male round goby urine to lure females to traps. Without this scent, we have shown that traps seeded with food or adult gobies are not effective in luring round gobies to traps. While our data are based on limited research, we do believe they are encouraging enough to warrant further studies into this area.†Contacts: February 4, 2008 Dr. Lynda Corkum (University of Windsor) 519-253-3000 x 2717 Dr. Marc Gaden (Great Lakes Fishery Commission) 734-662-3209 x 14 -------------------------------------- The Great Lakes Fishery Commission is an international organization established by the United States and Canada through the 1954 Convention on Great Lakes Fisheries.

Wildlife refuge is centerpiece of Detroit River's recovery Tina Lam / February 5, 2008 freep.com The Detroit River was once among the most polluted areas of the Great Lakes. Heavy industry along the Detroit and Rouge rivers dumped chemicals unchecked into the river. Wastewater treatment plants took only a little waste out of what they poured into the water. Phosphorus from detergents and fertilizer runoff fed thick mats of algae. When it rained, raw sewage overflowed municipal pipes and went straight into the river. The river also had extreme oil pollution, said John Hartig, manager of the Detroit River International Wildlife Refuge. In winter, most of the river would freeze, leaving a small area of open water for ducks and geese. Dipping into the open water, they often would get soaked with oil and die. Between the 1940s and 1960s, 12,000 ducks and geese died that way, Hartig said. But a new report assembled by a U.S. and Canadian team shows the health of the river has improved dramatically since those bad days. Oil spills have been reduced, phosphorus levels have declined by 90%, fish and wildlife are no longer heavily contaminated with now-banned DDT and PCBs. There has been huge progress in removing contaminated sediment from the river. Sewage treatment has improved. Mercury contamination is down 70%. "We've laid the foundation for the return of bald eagles, peregrines, sturgeon, whitefish, walleye and mayflies," Hartig said. "We have one of the most dramatic ecological recoveries in North America." Thirty years ago, peregrine falcons and bald eagles steered clear of the area; now bald eagles are nesting in seven locations along the river and 15 peregrines are seen often. Whitefish and sturgeon are reproducing. The international report tracked data going back more than three decades on 50 indicators of health in the river's ecosystem and in western Lake Erie. The authors said pollution controls in both the United States and Canada have led to impressive changes. More than $1.6 billion has been or will be spent by cities, including Detroit, to fix sewer overflows so raw sewage doesn't escape during heavy rains. The international refuge is symbolic of the changes. Created in 2001 with 304 acres, the refuge has grown to include more than 5,000 acres of coastal marshes, wetlands, islands and shoals. In the middle of a heavily urbanized area, the refuge is a haven for fish, birds and ducks and for people to walk, fish, boat or go birding. Anglers have taken fat walleye and sturgeon from the Detroit River, and the refuge is said to be one of the three top hawk-spotting sites in the country. The refuge has trails, wildlife viewing stations and an outdoor classroom. The Canadian and U.S. teams that put together the report said population growth, global warming, the loss of animal habitat, continued pollution and invasive species are still big problems. But for Hartig, the report is confirmation that the full cleanup job can eventually get done. The perception for decades of the Detroit River was of polluted water in a rust belt city. "It's no longer accurate," Hartig said. "We've come so far."

Little Current Fish and Game Club offers pickerel fingerlings to stock West End lakes Tom Sasvari manitoulin.ca MINDEMOYA-With declining walleye populations in at least a couple of Western Manitoulin lakes, the United Fish and Game Clubs of Manitoulin (UFGCM) have requested support from the Ministry of Natural Resources (MNR) to have some fish raised by the Little Current Fish and Game Club (LCFGC) stocked in these lakes. Jim Sloss, chair of the UFGCM, told representatives of the MNR at a meeting last week that the UFGCM has been offered fingerlings for stocking by the LCFGC. "There has been declining fish populations in Silver Lake and Tobacco Lake," he said. "Bill Strain (chair of the LCFGC) and I have been discussing this, and their club has been doing very well in stocking in Sheguiandah. They have indicated they would be happy to support us by providing fingerlings to put in the lakes on Western Manitoulin that need these fish." "There have been population declines over the past few years, and we want the MNR's approval to have fish raised by the Little Current club stocked in those lakes," said Mr. Sloss. "We would not likely oppose this," said Wayne Selinger, biologist with the MNR Espanola District Office. "I'm not sure Tobacco Lake needs more (walleye) stocking, and Silver Lake would probably be a better place to put them." There had been a good population of walleye in Tobacco Lake, but since MNR netting took place, "the fish population in the lake has declined substantially over the past year," said Mr. Sloss. Mr. Selinger pointed out permission will be required, and the Little Current club will have to make the request to the MNR. "They will need a stocking permit for this," he said. When asked, Mr. Selinger said stocking of walleye in Lake Mindemoya or Windfall Lake would not be supported. However, Jack Hayes pointed out, "Mindemoya has been the hardest fished lake for walleye on Manitoulin." Mr. Selinger said in tests conducted by the MNR in 1996, 2001, and 2005, the number of walleye caught per net was near the trap range for Ontario. "But, we need to keep an eye on this," he said. "We should do more tests no later than 2010. I will not argue the significance of the lake." Mr. Hayes pointed out the fishery was really good until about five years ago. "I'm a fishing guide and have not fished the lake (Mindemoya) for the past three years, because there are no fish." "I would hate to see any decline," said Mr. Selinger. "We will have to continue to monitor the lake."

Access complaints launched;Residents say MNR reserves tracts of land, lakes for tourists Rachel Punch thesudburystar.com Some Northern Ontario residents lobbying for motorized vehicle access to all roads on Crown land have taken their fight to the province's ombudsman. Simon Guillet, of Guilletville, sent in a complaint Jan. 23 calling on ombudsman Andre Marin to conduct a full investigation. He charges the Ministry of Natural Resources is reserving "huge areas of lands and lakes" for guests of remote tourist operators. "There is nothing wrong with having those expensive lodges and having people go to those lodges," Guillet said. "The problem is they seal off the area for miles around and it's private hunting and fishing lands just for them. "There is nothing wrong if, at least, we have equal access to that land, but they keep us out. I don't know if they can legally, but they do." At issue is access to forestry access roads. The ministry has decided to close some of the roads on Crown land off to motor vehicles. Tourist operators can still access land in these remote areas by plane. Outdoor enthusiasts such as Guillet charge the ministry's sole reason for restricting access is to protect these tourism operators. The ministry has denied collusion with or favouritism towards the tourism industry. The ministry argues the decision to close a road is based on a variety of factors, such as conservation. Protecting tourism is just one part of the planning, they say. The conservation defence is one Guillet would like investigated. He said some of these lodges on remote lakes have thousands of guests. The owners of Pine Portage Lodge and Kaby Lodge, which operates out of Wawa, even boast to have a nine-hole backwoods golf course. "Say you have to shut down a lake because it's depleted, you shut it down for everyone. You don't shut it down for the general masses and leave it open for the people who can afford to go to the lodges," Guillet said. Rod Jarmovitch belongs to Citizens Committee For Equal Access To Crown Land in Sudbury. The committee put in a complaint to the ombudsman's office in late summer. The group has also collected about 8,000 signatures on a petition, Jarmovitch said. "We're asking for basically equal rights," he said. "It appears as though the ministry has no regard for the general public's interest in accessing these areas," he said. "Our dollars paid for a lot of these roads that they are blocking off." Sault resident Tom Brason and Hawk Junction resident Mike Boudreau have each put complaints into the ombudsman's office on the issue as well. Brason said some of these lodges boast access to more than 100 lakes. "You couldn't bring your family up and go camping there. There is no way you could walk through the swamps and the bushes to get to these lakes, even though they have a right to go there," Brason said. "The MNR is playing little games here. Even though you have a right to go there, they think that they can stop you by controlling the road." Boudreau has been fighting the access issue since the 1980s. "It's just hard to believe what the MNR can do," he said, adding he has reams of documents to back up his arguments. Linda Williamson, Ombudsman Ontario communications manager, said she can't discuss the complaints because they are confidential. In some cases, complaints are resolved in a couple of weeks with a few phone calls. In other cases, it could be months, she said. "If a complaint needs to go to a full investigation, then it will," Williamson said. "If it's a huge issue, it could spark the ombudsman to make a report." Ministry of Natural Resources officials could not be reached for comment on Monday

....I stopped reading after this quote.... "I want to confirm that the intent of the regulation is for the registration of ice huts that remain on the ice for the season, or parts thereof, and is not intended to apply to anglers who take portable, cloth or synthetic ice huts with them when they go fishing, and take them off the ice at the end of the fishing day." Good enough for me.

Dedicated efforts restoring salmon Tuesday January 29 2008 caledonenterprise.com Dear Editor: The last one was seen in a tributary to Lake Ontario 110 years ago in 1898. It was an Atlantic Salmon, a species that had been native to the Great Lake since the initial post-glacial marine population of this body of water. It was extirpated in less that half a century. It is hard to believe this fish was abundant when our forefathers settled this area only a few generations ago. Early pioneer settlement, however, brought with it, clear-cutting, dams, mills and unregulated fishing that literally wreaked havoc on salmon-dependant watersheds on the north shores of Lake Ontario. The effects of habitat loss were insurmountable for this wonderful species of fish and it simply disappeared. The good news is that the story doesn't end here. It has come alive, through community-minded and environmentally-conscious citizens, who have united and are making a difference. At a recent Palgrave Rotary meeting, the guest speaker was Chris Robinson from the Ontario Federation of Anglers and Hunters Association (OFAH). Chris is the programme co-ordinator for the Atlantic Salmon Restoration Project for Lake Ontario. The OFAH together with key sponsorships, clubs, schools and government is in the process of turning back time. Under the leadership of the OFAH, a partnership was developed in 2005 and a four-part plan was put into play. It was based on an audacious goal to restore a self-sustaining population of Atlantic Salmon to Lake Ontario. Key accomplishments to date include; the completion of 25 stream rehabilitation projects; the release of 707,000 fish; outreach activities that involve 21 public schools raising salmon; and concentrated hatchery support from the MNR, three clubs and Fleming College. The 2008 activities will see the release and assessment of another 800,000 fish along with 20 incremental public school classroom hatcheries. Thanks to this outstanding effort, the day is fast approaching when we will witness an abundance of Atlantic Salmon, what our forefathers first saw when they reached the shores and tributaries of Lake Ontario. It is a wonderful example of the personification of power through caring volunteerism and daring to make a difference! Mike Goddard, Palgrave Rotary

Worried about Water Andy Riga, February 02, 2008 canada.com MONTREAL -- Your country is crisscrossed by innumerable rivers, some of which flow into three oceans. Yet Canada's fresh water isn't as abundant as you may think. And it's facing serious challenges and the looming menace of climate change, which is expected to exacerbate Canada's water problems and leave more of the world thirsting after our precious liquid resource. "They say you need a crisis before people get jerked into taking responsible action," says Chandra Madramootoo, a water researcher and founding director of McGill University's Brace Centre for Water Resources Management. "When are we going to finally say 'Jeez, we're not as water rich as we thought we were and maybe we better start doing something?' Is it going to be the day when we (must) ration water?" Some think the crisis is already here. They say it's time to take action -- by, for example, conserving water, cracking down on polluters, preparing for the effects of climate change and coming to the aid of waterless poor in the developing world. The map of Canada certainly has a lot of blue on it. Flanked by three oceans, graced with the grand Hudson Bay up top and part of the sprawling Great Lakes Basin down below, and pierced by the St. Lawrence from the east, Canada is a water titan. With six per cent of the world's "renewable" fresh water (water replenished by precipitation, runoff or groundwater recharge), Canada has the third largest collection of fresh water, after Brazil and Russia. But the map doesn't tell all. You can't drink ocean water, of course. (Desalination is costly and energy-intensive.) And 60 per cent of Canada's fresh water drains northward, away from where it is needed most -- along the band hugging the U.S. border where the vast majority of Canadians live. Also unseen on the map are Canada's many water troubles. "The problem is there are new threats coming down the line and we have all these ongoing issues that we haven't dealt with," said Tim Morris, national water campaigner for the Sierra Club of Canada, an environmental organization. In Quebec, blue-green algae plagues lakes. St. Lawrence water levels were so low this fall that water had to be pumped in from Lake Ontario. Montreal's crumbling pipes leak 40 per cent of their valuable cargo en route to taps. Water that reaches some Montreal homes has lead levels deemed potentially hazard to children under six. Upstream, the Great Lakes Basin, the planet's largest continuous body of fresh water, is surrounded by a huge population: 40 million people -- one in three Canadians, one in 10 Americans. The lakes face growing demand from industry, power plants, farms and urban sprawl. Water levels are at historic lows in some Great Lakes. On the Prairies, farmers have struggled with severe droughts over the past decade. Alberta's tar sands industry is a water glutton, using two to four barrels of fresh water for every barrel of oil extracted. Other Canadians don't have to look to Alberta to see water hogs. A mirror will do. Per capita, Canadians are the planet's second-biggest water consumers, behind Americans. The average Canadian uses 335 litres per day -- more than double Europeans' usage. And Canadian water use is growing (by 25 per cent over the past two decades), while other developed countries, including the U.S., have seen consumption drop. Canada's water gluttony is starker still. Most of the 1.1 billion people worldwide who are water poor must survive on five litres per day. That's less than a Canadian uses to flush a toilet -- even of the low-flush variety. Canada is in the midst of an "escalating water crisis," according to the Gordon Water Group, an organization of environmentalists, scientists, policy experts and former federal policy advisors. In a recent report, Changing the Flow, the group points to more water worries: Some Canadians, mostly in native reserves and rural and remote communities, don't have access to clean drinking water. Across Canada in December 1,174 boil-water advisories were in effect, Health Canada says. Raw sewage is still dumped into lakes and rivers by towns and cities. Twenty Canadian and U.S. cities flush about 90 billion litres of untreated sewage into the Great Lakes each year, according to Ecojustice, a Canadian environmental law organization. Fish populations are being decimated by contaminated water, excessive water withdrawals, and dams and diversions that also disrupt communities and affect recreational water use. Climate change is the most ominous threat on the horizon. Global warming caused by human activity -- largely by the burning of fossil fuels -- is being blamed for an alarming increase in the melting rate of glaciers in western Canada, leaving less water for drinking, crop irrigation and other uses. Climate change may also be causing the higher evaporation rates that are leading to low water levels in the Great Lakes. Warming from 1900 to 2003 led to a decrease in total precipitation as snowfall in the West and Prairies, says a recent report by the Intergovernmental Panel on Climate Change, an international group of scientists set up by the United Nations and the World Meteorological Organization to assess climate change. Cold and cool-water fisheries, especially salmonids (salmon, trout and chars) have declined as warmer, drier conditions reduce habitats. Other cold-water fish, such as walleyes and brook trout, are experiencing reduced productivity, the IPCC noted. Across Canada, "climate change is expected to directly affect both the quantity of water available and its quality, creating competing demands for this resource from multiple sectors," Environment Canada says. Changes will affect lakes, rivers, groundwater, glaciers, permafrost and wetlands, says Threats to Water Availability in Canada, an Environment Canada study to which about 70 scientists contributed. Wetlands -- which absorb and store greenhouse gases and naturally regulate the atmosphere -- make up 14 per cent of Canada's territory. Climate change may cause more evaporation, which might, in turn, dry up wetlands. Extreme weather events like droughts, storms, floods and ice jams are expected to be more frequent and severe. "Some experts say a temperature increase of two to four per cent could lower the average flow from Lake Ontario by 24 per cent," because of higher rates of evaporation and drier soils reducing runoff, Environment Canada says. A decrease of that magnitude in Lake Ontario, the major source for the St. Lawrence, "could result in a one-metre drop in water levels in some areas of the" river. Unusually low water levels -- which can impair navigation, stimulate growth of noxious weeds and kill fish -- would require more dredging of waterways, which would in turn harm organisms and spread contaminants. In total, fresh water is estimated to contribute up to $23 billion annually to the Canadian economy, Environment Canada says. Large swaths of the Canadian economy rely on fresh water -- from agriculture and energy production to manufacturing and shipping, all of which could be hurt by climate change, according to the Canadian Climate Impacts and Adaptation Research Network, a government-university initiative. Climate change isn't the only emerging threat to Canadian fresh water. Others include: Growing pressure on Canada to export its fresh water in bulk (as opposed to via bottled water) as populations balloon in increasingly arid areas such as the southern U.S. At least 36 American states could face water shortages by 2013 due to rising temperatures, increased evaporation, droughts, urban sprawl, waste and overuse, the U.S. government says. The growing presence in waterways of pollutants such as pharmaceuticals and personal-care products -- antibiotics, birth control pills, soaps and sprays, many of which are not removed by sewage treatment. The spread of invasive species. In the Great Lakes, they slip in as stowaways in ballasts of ships, threatening indigenous species. The most notorious invaders are zebra mussels and sea lampreys. They're installing more efficient compact fluorescent light bulbs and turning down furnaces. Some even think twice before needlessly idling cars. The spectre of climate change is spurring Canadians to cut energy use. But experts say they should think about water, too. McGill researchers hope to help cities collect rain falling on roofs and on highways, then pass it on for light industrial use such as cooling buildings. Another McGill team has developed a system allowing farmers to cut water use by up to 40 per cent. Sensors in the earth transmit moisture levels to a computer, which calculates how much water is needed. Some cities are cutting waste. "There's an opportunity to find new water supplies without piping it in from somewhere -- finding new water supplies from conservation," said the Sierra Club's Morris. "You save money on infrastructure, you save on energy use from pumping and treating water." He pointed to Durham Region, just east of Toronto. It's investing $17.2-million over 10 years on water efficiency and conservation. Building infrastructure to provide the amount of water that will be saved would have cost $125-million. Montreal is in Year Two of a $4-billion, 20-year plan to fix water infrastructure and install water meters in non-residential buildings. A 2002 study found decaying pipes cost the city tens of millions of dollars a year. Thanks to water-conservation efforts, Calgary uses the same amount of water now as it did 25 years ago, though its population has jumped by 400,000. Individuals can do their part by installing flow reducers on taps, taking shorter showers, switching to low-flush toilets, and not dumping dangerous domestic waste and prescription drugs down the drain. Water experts hope the focus on water brought on by climate-change concerns will also encourage governments to act. They saw a ray of hope in Prime Minister Stephen Harper's Throne Speech last month. He promised a water strategy to clean up lakes and oceans and improve access to safe water for First Nations. He said he would bolster protection of water and land through tougher enforcement that will make polluters accountable. The Conservative government has yet to provide details. The Gordon Water Group hopes its recent report will be a blueprint for federal action. Its 25 recommendations focus, among other things, on securing safe drinking water for all Canadians, responding to climate change, and promoting a culture of water conservation. Debunking the myth of limitless water is a starting point. "We have this tendency to just turn on our taps and think, 'Well, there's an endless supply there,'" said Morris of the Sierra Club. "But it's coming from somewhere and it's having an impact. Our water resources are not infinite and they do have a point where they're going to end up in trouble unless we do a better job of stewarding them." (Montreal Gazette) How climate change could affect Canadian water supply British Columbia - Warm temperatures cause glacier retreat. (Glaciers supply water for irrigation, drinking, and hydroelectric power. Runoff also maintains river habitat.) - Precipitation is more intense, with greater winter rainfall. - Lack of water resources lead to water conflicts. Prairie provinces - Declining water resources due to melting glaciers and less snow cover in Rockies. - More droughts, affecting crop irrigation, soil quality and wetland habitats. - Changes in water quality due to low flows. Ontario - Lower water levels in Great Lakes lead to increases in shipping costs and problems launching, operating boats. - Waterborne pathogens carrying infectious diseases proliferate in higher water temperatures. Quebec - Flooding affects over 80 per cent of municipalities located on the waterfront. - Extreme precipitation events and flooding overwhelm municipal sewer systems. - St. Lawrence River fluctuations affect fisheries, wetlands, water supply, hydro power, navigation and marinas. Atlantic Provinces - Rising sea levels cause erosion, flooding of coastal habitats. - Storm, tidal surges increase, leading to more frequent flooding. - Droughts affect quantity, quality, and allocation of water for agriculture.

LAKE ERIE COMMERCIAL FISHERMAN USES ILLEGAL GILL NETS News Release Ministry of Natural Resources January 31, 2008 CHATHAM — A Leamington commercial fishing company and a boat captain have been fined $3450 for using illegal gill nets. The Family Fish Co. Ltd., which owns a Lake Erie commercial fishing licence, has been fined $1150. The captain of the commercial fishing vessel Mummery Bros., John Lablance, 38, of Wallaceburg, has been fined $2300. The seized gill nets are forfeited to the Crown. On July 25, 2007, conservation officers were inspecting commercial fishing vessels in the Erieau harbour, on Lake Erie when they discovered 19 illegally undersized gill nets on the Mummery Bros. The legal minimum size of 57 millimetres (2¼ inches) is used to selectively harvest yellow perch of marketable size which have spawned at least once. Minimum mesh size and quotas help maintain healthy yellow perch stocks on Lake Erie. Justice of the Peace Calvin Hurst heard the case in the Ontario Court of Justice, Chatham, on January 31, 2008. The Ministry of Natural Resources monitors the commercial and sport fishing industry to protect Lake Erie’s fishery resources which are managed through an international partnership with the U.S. Great Lakes states. To report a natural resource violation, call 1-877-TIPS-MNR (847-7667) toll-free any time or contact your local ministry office during regular business hours. You can also call Crime Stoppers anonymously at 1-800-222-TIPS (8477).

It's always good to have a second option if the lakers are off. I've always wanted to take a winter trip up that way and Superior whities would be high on my target list.
