Gary, I certainly will not get into an argument with a guy with 43 years of experience. But please help me understand why our large, most productive lakes in MN have all been converted to 4(ish) or less limit?
Common themes have been population declines, do too overharvest, poor reproduction, lake chemistry changes, or imbalance of size structure. Now if this can happen on our 40-100+ thousand acres lakes, what is happening on our smaller walleye lakes? It takes a lot less harvest on a 800 acre lake to have an impact than on a 40,0000 acres. at 1 walleye per acre a of 4 person, 6 fish limits, is a harvest of 3% (.03) of the population(800 ac) vs 6/1000th of a 1% (.ooo6)(40,000 ac). Of course angler effort is different, I dont want to venture a guess on hrs/per acre angler effort. But simply, the majority of our walleye lakes are smaller in size and may be more prone to overharvest.
Stocked lakes that are essentially put and take lakes due to no natural reproduction, are a different bird. The DNR fisheries probably have most of those lake figured out on what stocking numbers need to be to sustain a long-term fishable population, that is with a 6 fish limit. is there possibly concern that with how effective anglers are today that those stocking levels will need to increase to make up for the increase in harvest? That will cost more money that we all know is in short supply for our DNR programs.
