Again, this is State-based data on large Res/lakes. I called head of region 1 to get the numbers from last years data.
723 CC sampled from 11 impoundments. Stomach contents were 73% empty, 11% plant or algae material, 9% invertebrate, 5% fish/bones/scales/plates, 2% unidentifiable.
Situation was specific to NON fed CC.
