It's a money fish, so people hold there spots pretty territorially! 20-25 crappies can make you up to 80 bucks! I've never done that many myself in a day but I think many people on the VT forum have! Good reason to keep it on the down low!
Yup, it's legal. There was talk last spring of reclassifying them to "sportfish" which would have made it illegal, but it didn't happen.
Last summer by the sandbar I went out every day for a week. I was bass fishing but saw the same 2 guys camping out on the culverts pounding the piss out of crappies for money. I spoke with them for insight and they were nice guys but damn....2 pails of fish a day. This isn't the ocean I'm not gonna get into the selling of fish debate but I will tell you that wiping spots dry changes the ecology of an area overnight.
