A commercial fishery is a sector of the fishing industry focused on catching fish and other seafood for sale and profit. This type of fishery often involves large-scale operations, including fishing boats, nets, and equipment designed to harvest significant quantities of fish. Common species targeted in commercial fisheries include tuna, cod, and shrimp. Commercial fisheries can be found in both marine and freshwater environments, and they play a crucial role in the global economy. They provide jobs, support local communities, and contribute to food supply. However, sustainable practices are essential to prevent overfishing and protect marine ecosystems.
