Bill thank you for the great info on crappie.My thought was to keep the crappie offspring to a minimum by putting in some big rainbow trout or big bass that all are sterile,i know i can get rainbows like that,not sure about bass. I want to eat alot of the crappie, is there a fish that taste better then a crappie? i thought i read about some fresh water perch that actually is better then a crappie, i find that hard to believe but am open minded and will raise them instead of crappie if necessary. I really love crappie, there some much fun to caught and to eat.Bill how about the ice cold spring run off that fills the lake, will it be to cold for warm water fish like crappie or big perch? The lake also freezes over solid ea. year. I am going to install an aerator soon so that doesn't happen.The water is really cold up in Idaho hope that won't be a problem. Thanks Bill
