I put 40 3 inch Walleye in my 1/2 acre pond that at the time was over run with crayfish and young bluegill. Fast forward 3 years and I can't catch a crayfish or a young bluegill. My walleye are around 14 inches long and shaped like a cigar. My bluegill are big and fat. The only feeding I do is hand feeding on the occasional calm evening.
