Fishing is the activity of trying to catch fish using various techniques like nets, angling, or traps. Different countries have unique fishing methods - some use boats and nets to catch schools of tuna and sardines offshore, while others stand on stilts in shallow waters in places like Sri Lanka. Many people rely on fishing for their livelihoods and income, working for companies that trade and sell fish. While fishing provides food and economic benefits, it is important to preserve natural resources to ensure their sustainability.
