I always try to clean them when I get home as well but as long as they are packed in ice, they will last a couple days. I'm not saying that this should be the norm but if it happens, pack em in ice and don't let them go to waste.
BTW, my experience is with Perch, some cold water species might not fare as well. I've had Steelhead meat change color rather quickly before when the fish was left in the livewell for awhile during the summer. Still seemed to taste OK but I did notice some loss of color in the meat.
