A fish net is a type of netting used primarily for catching fish and other aquatic animals. It is typically made from strong, flexible materials like nylon or cotton, and comes in various shapes and sizes, including gill nets, seine nets, and cast nets. Fish nets are designed to trap fish while allowing water to flow through, making them effective for both commercial and recreational fishing. Fish nets can be used in various environments, such as rivers, lakes, and oceans. They are often employed by fishermen and aquaculture operations to harvest fish like salmon, tuna, and trout. Proper use and maintenance of fish nets are essential to ensure sustainability and minimize bycatch, which refers to the unintended capture of non-target species.
