Fishing is when people catch fish from the water so that they can eat them or sell them.
There are lots of different ways to catch fish. One is using a fishing rod and some bait. The bait is something that the fish likes to eat, like a worm, and the fish will swim over to it and try to eat it. Then, the person will use their fishing rod to hook the fish and pull it out of the water.
Another way to catch fish is with a big net. A net is like a big bag that is thrown into the water with weights at the bottom and floats at the top. This way, the net sinks down and traps the fish inside. The net is then pulled up and the fish can be sorted out and kept.
Fishing is a big industry because people like to eat fish and it's also an important source of income. It's important to make sure that there are enough fish in the water for people to catch and eat, but not too many that they will die out. This is called sustainable fishing, and it's something that fishermen, scientists, and governments work together on to make sure that there will always be enough fish for people to eat.
