Ring nets are a type of fishing gear designed to catch fish efficiently. They consist of a large net with a circular shape that is often used in commercial fishing. The net is deployed in the water and can be drawn in to trap fish, making it effective for targeting schools of fish. These nets are typically made from durable materials to withstand the rigors of ocean conditions. They are often used in conjunction with boats and other fishing equipment, allowing fishermen to capture a variety of species, including tuna and mackerel, in a sustainable manner.
