It's too long for me to read, frankly.

Of course, all we are doing is speculating on the original poster's anecdotal information. As such, it's hard to see how one can then make conclusions that seem to be presented as definitive information.

From what I can tell, the OP has strong case of overpopulation of Black Crappie, a lack of forage, and a lack of predators that can keep Black Crappie numbers down. Material changes have to be made to right the ship.
