Northern Brook Lamprey

Features: The Northern Brook Lamprey (Ichthyomyzon fossor) has the characteristic features of lampreys -- a round mouth and teeth arranged in a circle -- but this species is non- parasitic and the larvae feed on diatoms and protozoans. This species is small (9-16 cm long) and is easily confused with other native lampreys. As indicated by its common name, this species lives in small rivers. Adults spawn in gravelly riffles and then die. Individuals can lay over 1,000 eggs. When the larvae (called ammocoetes) hatch they make burrows in soft mud and spend six years growing. Then they metamorphose into an immature adult stage which lasts over winter (about 8 months) and then they develop sexual maturity quickly, emerge from the mud and disperse as adults to the spawning grounds. Adults never feed and live for about a year before dying.

 

Status: Special Concern Provincially and Nationally

 

Range: The Northern Brook Lamprey lives in the eastern United States in the upper Mississippi and southern Hudson Bay drainages, ranging from Manitoba and the Great Lakes region south to Missouri, east to the St. Lawrence River. In Ontario, it lives in rivers draining into Lakes Superior, Huron and Erie, and in the Ottawa and St. Lawrence Rivers.

 

Threats: The Northern Brook Lamprey prefers warm water and it may never have been common here. Ontario populations have declined because of the application of non-selective chemicals in streams to control the introduced Sea Lamprey, which is a parasitic species and a threat to Great Lakes fisheries. The species persists in untreated streams, above barriers and in backwater areas, which are not affected by the treatments. Water drawdowns and siltation are also potential threats.

 

read enough to know what constitutes being a parasite...

 

Good ol Andy.LOL

They are parasitic and feed by sucking fluids out of trout and salmon by attaching to them with their sucker mouth and rows of teeth. They almost decimated the fisheries in the great lakes many years back. Much money has ben and will be spent to control their numbers.

Speaking of lampreys, wanna have some fun, those things spawn after trout in may/june in shallow rocky streams, they line up in pairs males and females, you try to sneak up behind them and with the white cotton gloves you use to tail steelhead, you reach down and try to catch them before they see you. the best creeks to do this on are also the best ones for trout. Honest its really exiting, plus your doing the trout a big favour, they will thankyou with many memorable days of double digit steelhead. By the way that sure is a biggun

Many years ago fishing from shore in Lake Erie with a neighbor and his dad in Cleveland his dad caught a sheephead. It had a lamprey attached to it on the soft flesh under the gill plate, also seem catfish with marks on them from lamprey usually right where the head ends.

 

We killed that one, I have no feelings of guilt over it. Never had an issue with killing a gobie, though bait would have been a better plan if legal

 

Got to watch the history, plenty of blame to spread around on why some species are no longer common sights in the great lakes and elsewhere, most of it human activities.

 

Dad used to tell m of sturgeon being thrown on shore and left for dead when he was young, people thought they were ugly.

 

Commercial netters here in Ohio would never take any responsibility for diminished walleye populations. Always claimed that they weren`t taking enough to harm the population, blamed it all on pollution. But within a few years of their licenses being bought by the state and commercial walleye netting being banned Lake Erie was full of them.

 

Also heard stories of lamprey being the cause of lake trout disappearing, but after seeing some of the fishery abuses and the blame game played who knows for sure. Still don`t like them, not a big fan of sheephead and carp either.

have a major dislike for these damn things. two friends and i went on a mission of destruction many years ago back in good ole new brunswick's hammond river. 181 of these life suckers in two days removed from a geat fishery. for about 3 weeks every year these nasty's took over a river comparable in size to the credit.
