Okay kiddo, have you ever gone fishing with a rod and reel? Remember when you caught a fish and you had to take it off the hook? Well, sometimes when people catch really big fish, they need a little extra help to bring the fish on board. That's where a fishing gaff comes in.
A fishing gaff is a long stick with a sharp hook on the end. It's kind of like a giant fishing hook. When a fisherman catches a big fish, they use the gaff to stick the hook into the fish and lift it out of the water. The gaff helps the fisherman get a better grip on the fish so they can bring it on board the boat without it slipping away.
It's really important for fishermen to be careful when using a gaff because it can hurt the fish if it's not done correctly. That's why they usually use a gaff for catching big fish that they plan to release back into the water later. It's to make sure they don't hurt the fish too much when they bring it on board.
So there you have it, a fishing gaff is like a giant fishing hook that helps fishermen catch and bring big fish onto the boat safely.
