Definition and description of Cast Net

Definition and description of Cast Net A cast net is constructed from a series of tailored netting sections joined together to produce a cone-shaped net with weights and a drawstring attached to the perimeter and cast by a fisher to catch fish. Netting at the funnel end may be arranged such that the net hangs in a series of sculpted pockets to aid in the retention of fish. More elaborate cast nets include brail lines that run from the lower edge and are held by the net thrower which are slowly drawn together and form large pockets in the net. The line attached to the apex of the cone is used to assist casting and retrieval‎ of the net allows the brail lines to be tightened. Fishing vessel and handling equipment  No vessels are required to operate a cast net, and no shore-side equipment is used to operate the gear. Fishing operations A cast net may be cast from the shore, a bridge or pier, or from a small boat. Special skill or practices are required to cast the net to result in a desired net shape and at a far distance from the shore. Once the lower edge of the net is in water, weights around the perimeter help the net to sink quickly to prevent fish from escaping from the side. The drawstring is pulled to closes the bottom to prevent fish from escaping downwards. As the net is retrieved fish bounded by the wall of netting become entrapped or enmeshed. The entire net is pulled to the shore to retrieve the fish. Target species   Cast nets often target small schooling species of fish and shrimp near the surface. Geographical area Cast nets are used in marine waters in coastal shorelines and in inland waters all over the world. They are usually used in small-scale recreational and substance fisheries. Environmental impact  Cast nets have hardly any negative environmental impacts since the expected catch is small. When small or juvenile fish or undesired species may be caught, they can be released alive with minimal impacts. Type of gear (active/passive)
