chinook salmon

Whats the procedure for storing chinook salmon while camping/fishing for a few days?

We want to camp for a few days and fish for salmon. We'll have our motorhome and want to freeze what we catch the first couple days. What needs to be done to the fish to make it legally stored so we can show the fish & game officer if they ask. Do you just have to keep the head & tail on? Or ? Thank you very much for your time!!

Question on 2 pole permits in Idaho

Every year I purchase a 2 pole permit in Idaho for salmon, trout, and steelhead fishing. The question I have is very specific and pertains to getting close to limiting out on your daily limit.If an angler is 1 fish away from the daily limit, be is salmon, trout or steelhead can that angler still use 2 poles to catch the last fish. I have looked through the regulations and could not find any specific information on this. I was told by another angler over the weekend that if you are 1 fish away from your limit that you can only fish with one pole until you catch that fish.
