When I keep a fish I put them on a stringer and when I leave the fishin spot put them in tha car and then in the fridge when I get home. So I put one(2lb channel) in the fridge Saturday at around 7:00pm and Sunday around 8:00pm the fish was still alive. First I just find it amazing the length of time cats can hold their breath. Second how do you guys handle your keepers? What's a more humane way to handle them? I find it easiest to skin with the head and I'm not sure how to kill the fish quickly to avoid torturing them. Thanks for you input.
