rainbow trout

Copy fishing licence

Can I make a copy of my fishing licence and keep one in my tackle box and one in my wallet so if I forget my wallet I can use the copy thats in my tackle box or if my wallet gets stolen I can still fish? Will it be valid, or is the illegal for some reason? If so why? thx, Isaac

When I bring home trout I tend to fillet them leaving some waste. Can I use the head or any other part as catfish bait?

I know in some states, using any part of a game fish as bait is illegal. I also know that trout must be killed when removed from the water where they were harvested. I just hate wasting the head and tails of trout carcasses if I could be using them to catch catfish. Thank you.
