I have had many discussions regarding the merits of restocking. The greatest concern being the impact the commercial fishery would have on the stocked population. Below is the reader digest version of the Red Lake story from Minnesota. The Walleye fishery was destroyed by both fisheries. The conditions were so bad the black crappie population exploded. Keep in mind there is a gill net commercial fishery and sports fishery on that lake today. Restocking can work if all groups contribute.
There were three major stockings done for restoration purposes into the Red Lakes. The initial stocking in 1999 was approximately 42 million fry, with 31 million in 2001, and 32 million in 2003.
Eggs were obtained by MN DNR from the Pike River run from Lake Vermilion. Eggs were incubated, hatched, and marked at a DNR hatchery near Bemidji. The Red Lake DNR assisted with marking and distribution of fry to Red Lake.
Estimated costs for egg collection, hatchery and administrative costs were approximately $68,000 per stocking event. The Red Lake Band and the Bureau of Indian Affairs, reimbursed the MNDNR $40,000 per stocking event. All three of these stocking events were exceptionally successful. I am certain that the restoration cost to MN anglers will be very quickly recovered in angling opportunity and economic return from the incredible fishery that has developed.
In addition to the restoration stocking, there were two smaller evaluation stocking events in 2004 and 2005 using 4-7 million fry. Though full scale stocking was no longer necessary it was important to have some marked fry in the system to be able to estimate wild fry production and recovery progress. This proved valuable by documenting exceptional wild fry production from our restored brood stock in excess of our earlier stocking efforts.
Eggs for the evaluation stockings were collected directly from the Blackduck River tributary to the Red Lakes by the Red Lake DNR and incubated and marked in the MNDNR hatchery. Since the Band did the egg collection and the State did the incubation, no reimbursement was exchanged for these collaborative efforts.
It should be noted that besides the actual costs and monetary reimbursements there has been considerable collaboration on all aspects of this recovery effort, of which egg collection and fry stocking has been just one part of a much larger process.
Thank you for your interest and feel free to contact me with any further questions.
