My father and I use to fish tournament years ago. Theses were small (10-20 boats total). It was fun and rarely had dead fish, Im sure there were a few that died as they swam away. Don't fish tournaments anymore its gotten to where a lot of these guys have heads swelled up like a watermelon. (Maybe they aren't getting taken care of at home). I think if your going to have these large tournaments things need to change possible having these fish weighed after catching them and immediately releasing them.Can't expect fish to stay alive in a livewell for 1-8 hours in 90-100 degree temps.
