My 5 year old son caught a nice 18 inch rainbow trout today and we are debating if we want to get it mounted. What size do most people want the fish to be to get it mounted? Do most trout run about $11 an inch? I know some people wouldn't want anything mounted that is stocked, and I understand that. But this was a special moment. I asked my son what he wanted. One minute he says he wants it on his wall, the next minute he says he can't wait to eat it. We took some good pictures so I think we are just leaning toward getting an 8x10 photo for his wall and having the fish for dinner tomorrow.
