Thanks guys: I read lots of stuff about g.shad: they are fragile, like die from quick change in temperature. I have buried many that wash up here and there on the shore line, it is always the g. shad, not the other fish.

There were some articles like "Nutrient Recycyling by fish supports more primary production as lake productivity increases"
they like turbid water which we have since 04.

The conclusion was that this fish is really contributing to the nutrient load by stirring up the bottom, and creating its own waste, and hurting the other fish by eating all the zooplankton,
would you agree with that theory?
