I never heard any of the TD's say anything about a no cull rule last year. Even though it is a lake wide rule during the summer. And they were all 5 fish limit tourneys last year.
As far as dead fish, I just dont get how people just let them die. I fished a ton of summer stuff last year and almost everyone of my fish were in 30-50ft of water and i never had any die on me. Ice the livewell in the morning with rejuvenade, keep the same water all day on recirc. Fizz the fish, I put weighted cull balls on them so they stay upright. I saw a lot of dead fish at weigh ins last summer, but happy to say mine swam off like rockets. Benefit tournaments were by far the worst for dead fish. The fish def. dont benefit one bit from it
