Some fisherman didn’t fight to release a snag on his line so just broke the line and left, ignoring the other end where a fish was later hooked! The fish still had some life in it but the hook had moved deep into its body fighting for a long time. I couldn’t do much about this poor little fish!
BTW...if you don't know what different species look like...you can wind up getting a ticket or two from a game warden. You owe it to yourself (and the fish), to know what they look like. And a warden will expect you to know.
