The net used for trawling is called a trawl.

Fishing net (or fishnet) is one of the oldest tools for fishing. It is a net woven from thin fibers to resemble a grid. First nets were made from natural materials like grass, flax, tree fibers, and cotton while today, most of fishing nets are made of nylon (although there are still nets made of wool or silk).

Gill Nets, Drift Nets and Tangle Nets: These type of nets hang in the sea like a wall and catch fish that swim into them. Gill nets are so called because fish get caught by the gills, while tangle nets unsurprisingly see the fish become tangled in the netting.

Network for Fish Quality Management and Sustainable Fishing (NETFISH) is a society formed in 2006 under the aegis of Marine Products Export Development Authority (MPEDA), Kochi. The Society is registered under the Travancore–Cochin Literary, Scientific and Charitable Societies Registration Act, 1955.

The fisherman wades into deep water and submerges the net, holding it upright with the central pole. When a fish swims into the net the fisherman tilts the pole backwards to scoop the net upwards, thereby trapping the fish.

Eight million metric tonnes of plastic leak into our oceans each year. These nets continue to trap everything in their path, presenting a major problem for the health of our oceans and marine life. Ghost nets don’t only catch fish; they also entangle sea turtles, dolphins and porpoises, birds, sharks, seals, and more.

The water can become toxic, and it—along with antibiotics, pesticides, parasites, and feces—is spread to surrounding areas, contaminating our oceans. Wild fish populations can get sick and die when parasites and chemicals are spread to them from these farms through the water.

After death, their rotting carcasses draw in still more victims and the cycle goes on and on, basically forever. This is not hyperbole. The plastics that make up most of the nets in the oceans today take around 600 years to break apart.

Net losses may be in the form of fragments or pieces of netting, or larger quantities when fishing vessels need to cut gear adrift for safety reasons (often in very bad weather conditions) or when they have snagged an underwater obstruction and are unable to free the gear.

Ghost fishing is a term that describes what happens when derelict fishing gear ‘continues to fish’. a cost-free solution is provided to fishermen to dispose of old, derelict or unusable fishing gear and to reduce the amount of derelict fishing gear in and around coastal waterways.
