I honestly don't think the feed situation will be a problem in pymy. The alewife population is unreal. I don't ever remember going out and seeing the bait-balls like are out there now. You go out there on a decent sunny day and there are 1000's of alewives in groups all over the place. One day last summer I had 20 different schools around me with easily 10,000+ fish in it (and that was all I could see right around me). The other thing is the perch population. When you catch 75 perch while drifting and the largest is 10", that just means food for the walleye. The lake could easily sustain a large population of big walleye.
I agree it is nice to go out there and catch 30+ walleye again, but this lake can easily produce trophy sized fish. When every fish that hits 15" is kept, then of coarse trophy fish will be few and far between. I know this lake is a put and take fishery, however, with the alewife and perch populations, the walleye are growing quicker then before.
As an added note, I would also like to see them reduce the limit to 3 or 4.
