On multiple day trips I've always either let my fish freeze whole, or cleaned & vac sealed so that they can be counted per the regs if a warden stops by. If you clean your fish, you can't store them out on the lake. Leaving a truck at the access solves this problem. fish in cooler, cooler in truck, truck on shore. 1 individual piece of meat is considered a fillet, and 2 fillets is considered a fish per the regs. so if you're not the best at cleaning fish, and tend to do them in pieces, maybe just freeze/store them whole and clean them when you get to your residence. I'm no warden, but I've never had issues when checked and had fish from a previous day in possession. the warden's numbers are listed in the fishing regulations if you have questions, best to chat with one from the area your fishing to see what method he prefers.
