fishing: the fish can take the bait or not and if I catch it I can always put it back into the water.
hunting: their is no bait, you just look for signs, get up into a tree and when something walks by you shoot it. It doesn't see you, there is no bait and it dies. No catch and release in hunting.
Here's me fishing: I catch the fish, take a picture of the big fish, and then puts it back.
