I figured Id post this here as it would be an interesting discussion:

When I keep fish, I usually examine what the were eating and Im sometimes surprised what I find. This year the crappie have had a mushy 'farina' like goo in their upper stomach. It is a lite tan/cream color with the texture of farina/cream of wheat. Any idea what that is? This is on large 11-14 inch fish.

I know when they are young they focus on zooplankton as a food source but as they get older they move onto larger food such as fry. Do they still feed heavily on plankton as adults when fry are getting scarce?

This is on late ice in NY
