Bob :

When ML started thinking about this several mths. ago I started looking at studies again to add to what I thought I knew. There are a lot of studies out there ( I would guess at least 100) and they cover many angles , questions and factors with much uncertainty remaining. Just a list or bibliography of the studies and there main points would be quite an undertaking and would help with questions that arise. After reading until my eyes were about to fall out I can safely say that crappie are an enigma within a conundrum. Keep us posted on what is to come.
