Major fishing techniques. Bottom trawling is destructive. Commercial fishing uses many different methods to effectively catch a large variety of species including the use of pole and line, trolling with multiple lines, trawling with large nets such as seine-netting, and traps or pots. [6]
Longline fishing, or longlining, is a commercial fishing angling technique that uses a long main line with baited hooks attached at intervals via short branch lines called snoods or gangions. [1] A snood is attached to the main line using a clip or swivel, with the hook at the other end.
Mostly, recreational fishers use angling methods and commercial fishers use netting methods. There is an intricate link between various fishing techniques and knowledge about the fish and their behaviour including migration, foraging and habitat. The effective use of fishing techniques often depends on this additional knowledge. [1]
Angling is the principal method of recreational fishing, but commercial fisheries also use angling methods such as longlining, trotlining or trolling. In many parts of the world, a fishing licence is mandated for angling and size limits apply to certain species, meaning by law, fish below and/or above a certain size range must be released alive ...
Reef net fishing is considered one of the most sustainable fish-catching methods, resulting in minimal bycatch. On the reef net, any non-target fish are tossed back into the water, resulting in ...
Trawling is an industrial method of fishing that involves pulling a fishing net through the water behind one or more boats. The net used for trawling is called a trawl. This principle requires netting bags which are towed through water to catch different species of fishes or sometimes targeted species.
For example, in February 2020, fishing in the Dominican Republic was a 93.4 million USD industry, but illegal activity by both local and foreign fishers from Honduras, Nicaragua, and South Korea have caused a deficit in fish; as a result, the country is forced to import fish that could otherwise by caught or farmed within its sovereign borders.
Commercial fishing showing the abundance of fish species caught using a trawling method. Unsustainable fishing methods refers to the use of various fishing methods to capture or harvest fish at a rate that is unsustainable for fish populations. [1] These methods facilitate destructive fishing practices that damage ocean ecosystems, resulting in ...
