There is nothing wrong with keeping the fish as long as they eat them. Whats so different then eating a burger. The thing they put the cows threw is a 100 times worse then that. I agree it is more humane to have a live well but you have to remeber 90% of the people they clean the fish do it while they are still alive atleast they were probably dead before that. And besides it sounds like you do it for a sport anyway not to eat. And i find it hard to believe that keeping 4 fish to eat will hurt the population. And i promise your state keeps an eye on things like this there are regs for a reason.
