Sport fishing is when people catch fish for fun! It's like a game where the goal is to catch the biggest or most interesting fish possible. People use special tools like fishing rods, bait, and hooks to catch the fish. Once they catch a fish, they usually take a picture or measure it before they release it back into the water. Sport fishing is usually done in places where there are a lot of fish, like in lakes, rivers, or oceans. It's important to follow the rules and regulations to make sure everyone is safe and the fish populations stay healthy.
