Commercial fishing methods use live fish to catch fish. These are usually caught with a semi-automatic machine, which impales the live fish onto a hook. The fishing method causes a large amount of suffering to the fish, since it takes a long time to land and is often surrounded by predators. Many of these fish are dead upon landing. In addition, the live bait and capture long periods mean that they may be eaten by predators.
Another common commercial fishing method is long-lining. This involves putting out a line from a fishing boat, usually up to 80 miles long. The fishing line is supported with floats or flags, and branch lines are sunk to the ocean floor to catch fish. One hook may be attached to a long line, which can reach depths of about 55 meters. During the process, the fishermen may also land a shark or billfish.

Many people working in commercial fishing are self-employed, which means that some or all of their income is dependent on the sale of the fish. In the UK, these workers are known as a share fisherman. These people work without an employment contract but depend on their share of the boat’s profits and gross sales. As a result, the commercial fishing industry is a multi-billion dollar industry, which relies on the continued growth of the fishing industry to ensure its sustainability.Know more here about Multimedia Projector
While the fish caught through gillnetting are still used in some operations, more modern technology has also made a difference. For instance, a boat that specializes in fishing for crabs, also known as a ‘fish trap boat’, is equipped with automated windlasses and specialized entrapping aids to catch a crab. Another type of commercial fishing method is called a ‘drifter’.
