A cast net is a type of fishing net designed to catch fish by being thrown over them. It is typically made of mesh material and has weights around the edges to help it sink quickly. When thrown, the net spreads out in a circular shape, trapping fish as it lands. Cast nets are commonly used in shallow waters, such as estuaries and coastal areas, where fish are abundant. Using a cast net requires skill and practice to ensure it opens properly upon landing. Fishermen often target species like shrimp and baitfish with this method. Cast nets come in various sizes and mesh openings, allowing users to select the right one for their specific fishing needs.
