My son and daughter were in a local fishing derby over the weekend and the question got raised as to the already caught fish. My daughter caught her fish after the offical scales had closed for the night. My question is once caught, killed and put in the fridge, how long do we have before the meat spoils? I know with my limited experience hunting big game, feild dressing is done ASAP. Is there a suggested or required cleaning time limit for fish(lake trout) that anyone can help us with for next time?
