I am kinda like Bigbaddad where I keep enough to get me at least 6 months of fish and then I typically switch to other species to catch. Usually by the time I get through the spring run I have enough to keep my family stocked along with my father and mom. I do like to hit the crappie under the lights during the summer to keep my stock up, then I usually hit the bass and stripers and later hit the Lake Michigan trout and salmon run in late summer. I wish I had the problem all the time to worry about but the 2 pounders are few and far between but I think I would throw them back regardless of genetics or not, I think we all agree they do produce a lot of eggs meaning more crappie for the future. No matter what your opinion or what you do, I hope we all run into this situation a lot on deciding to throw back or put the knife to them and I would never blink to see anyone fileting a three pounder except wondering why they didn't put it on the wall.
