Fry and fingerling sized fish rarely show up in lake assessments due to the fact that the gear used to sample the fish (usually trap and gill nets)does not sample such small fish very well. Because of this, managers typically exclude these small fish from their assessments so they do not skew their calculations. They do have other means to measure the amount of young-of-year in a fishery, but it does not sound like that was the type of sample they took from your statement.
As for the cormorants, while there is no doubt they do eat some walleye fingerlings, I would bet they are a fairly small part of their diet. I don’t really understand your statement about how, according to my statement, it would stand to reason most of that pound a day would be walleye. When I first stated that fish this size represent the largest population density and would not even be at a harvestable size for at least another three years, I meant the largest poplulation density of the walleye population, not the entire biomass of the fishery. There are countless numbers more baitfish and young-of-year fingerlings of other game fish species that will far outnumber the fry or fingerlings of just the walleye. I would bet that the cormorants are eating much more other fish, such as small ciscoes/whitefish, perch, shiners and other minnows, and panfish that the numbers of walleyes eaten even with the 60,000 sampled is still a minuscule amount of fish.
A separate question that goes along with my opinion that the general public (to a point) should stay out of fisheries management (the public is an important source for tools such as creel surveys). While I don’t personally know the mayor of Walker, what a mayor of a small town know about stocking? It is much more complicated than just “dumping” a bunch of fish in the water and doing so would screw up the managers models.
I agree 100% about not going into politics that affects the DNR. Like you said, way too much going on to want to write or read about.
All of those lakes you mentioned have many other issues going on (a lot of it politics that we agreed not to get into) that affected the walleye fishing. Although, I don’t see a problem with the walleye fishing on any of those lakes currently. Red is probably the best walleye lake in the state right now (anyone who has been up there for crappies is well aware of that), Winnie is still an excellent walleye lake, Leech may have a problem but that is what they (managers) are trying to figure out, Tonka walleyes are very abundant but you may have to look in different areas, and Mille Lacs is still a excellent lake you just may not be able to keep everything you catch.
Most of the time lack of fishing success can be blamed on increased fishing pressure/harvest and/or habitat changes within the fishery that causes the walleyes to move from “typical” structure.
One of the reasons the Alex area lakes are stocked so heavily is that those prairie pothole lakes typically don’t have the best natural reproduction (when compared to the fishing pressure those lakes receive) but they do respond to stocking very well. The stocking efforts get the best results in those areas so those areas get the most attention. Plus, there are A LOT of lakes in that area of the state so if you add up all the stocking that takes place, it is a lot compared to the rest of the state.
If it means that walleye fishing in Leech Lake will be better in ten years than it is now, then 60,000 fingerlings is a small price to pay. If the DNR finds that stocking is working on Leech by looking at these fingerlings, it will not take but a year or two for them to put WAY more fingerlings back into the lake than they will take out. If they find that stocking is not working, they for one, will look at other means to improve the walleye fishing and two, concentrate their stocking efforts to other lakes and other areas of the state.
