The black-browed albatross, also known as the black-browed mollymawk, is a large seabird of the albatross family Diomedeidae; it is the most widespread and common member of its family.
Bycatch, in the fishing industry, is a fish or other marine species that is caught unintentionally while fishing for specific species or sizes of wildlife. Bycatch is either the wrong species, the wrong sex, or is undersized or juveniles of the target species. The term "bycatch" is also sometimes used for untargeted catch in other forms of animal harvesting or collecting. Non-marine species that are caught but regarded as generally "undesirable" are referred to as rough fish or coarse fish.
The Antarctic toothfish, also known as the Antarctic cod, is a large, black or brown fish found in very cold (subzero) waters of the Southern Ocean near Antarctica. It is the largest fish in the Southern Ocean, feeding on shrimp and smaller fish, and preyed on by whales, orcas, and seals. It is caught for food and marketed as Chilean sea bass together with its sister species, the more northerly Patagonian toothfish. Often mistakenly called "Antarctic cod", the Antarctic toothfish belongs to the notothen family (Nototheniidae), a group of fish species abundant near Antarctica.
The Patagonian toothfish, also known as Chilean sea bass, mero, icefish, and Antarctic cod, is a species of notothen found in cold waters between depths of 45 and 3,850 m in the southern Atlantic, Pacific, and Indian Oceans and Southern Ocean on seamounts and continental shelves around most Subantarctic islands.
The yellowfin tuna is a species of tuna found in pelagic waters of tropical and subtropical oceans worldwide.
Gillnetting is a fishing method that uses gillnets: vertical panels of netting that hang from a line with regularly spaced floaters that hold the line on the surface of the water. The floats are sometimes called "corks" and the line with corks is generally referred to as a "cork line." The line along the bottom of the panels is generally weighted. Traditionally this line has been weighted with lead and may be referred to as "lead line." A gillnet is normally set in a straight line. Gillnets can be characterized by mesh size, as well as colour and type of filament from which they are made. Fish may be caught by gillnets in three ways:
- Wedged – held by the mesh around the body.
- Gilled – held by mesh slipping behind the opercula.
- Tangled – held by teeth, spines, maxillaries, or other protrusions without the body penetrating the mesh.
Commercial fishing is the activity of catching fish and other seafood for commercial profit, mostly from wild fisheries. It provides a large quantity of food to many countries around the world, but those who practice it as an industry must often pursue fish far into the ocean under adverse conditions. Large-scale commercial fishing is called industrial fishing.
Cetacean bycatch is the accidental capture of non-target cetacean species such as dolphins, porpoises, and whales by fisheries. Bycatch can be caused by entanglement in fishing nets and lines, or direct capture by hooks or in trawl nets.
The billfish are a group of saltwater predatory fish characterised by prominent pointed bills (rostra), and by their large size; some are longer than 4 m (13 ft). Extant billfish include sailfish and marlin, which make up the family Istiophoridae; and swordfish, sole member of the family Xiphiidae. They are often apex predators which feed on a wide variety of smaller fish, crustaceans and cephalopods. These two families are sometimes classified as belonging to the order Istiophoriformes, a group which originated around 71 million years ago in the Late Cretaceous, with the two families diverging around 15 million years ago in the Late Miocene. However, they are also classified as being closely related to the mackerels and tuna within the suborder Scombroidei of the order Perciformes. However, the 5th edition of the Fishes of the World does recognise the Istiophoriformes as a valid order, albeit including the Sphyraenidae, the barracudas.
In fishing, incidental catch refers to the portion of the catch that was unintentionally caught but retained. It can be distinguished from discards, which are the unintended catch that is caught and then returned to the sea, and bycatch, which includes all non-targeted species caught alongside the targeted species.
The South East Atlantic Fisheries Organisation (SEAFO) is an organization that maintains controls over fishing and fishing related acts in the Southeastern Atlantic Ocean.
A mammals and birds excluder device or MBED is a device added to fishing gear that avoids the killing of marine mammals and seabirds during commercial fishing. This device was designed mainly for the interactions with toothed whales: sperm and killer whales.

As with other countries, the 200 nautical miles (370 km) exclusive economic zone (EEZ) off the coast of the United States gives its fishing industry special fishing rights. It covers 11.4 million square kilometres, which is the second largest zone in the world, exceeding the land area of the United States.
Mahi-mahi are swift and acrobatic game fish with striking colours. These colours darken when the fish dies The current IGFA all tackle record is 39.91 kilograms (88lb), caught in 1998 in Exuma, Bahamas by Chris Johnson of Lake Mary, Florida. Catches average 7 to 13 kilograms, and any mahi-mahi over 18 kilograms (40 lb) is exceptional. Males are often larger than females.
The Republic of the Marshall Islands has a commercial fishery that targets bigeye and yellowfin tuna using pelagic longline fishing gear. There were 55 longline vessels licensed to fish in the Republic of the Marshall Islands Exclusive Economic Zone (EEZ) in 2011, of which 4 were Marshall Islands-flagged and 51 were foreign-licensed vessels, including 22 Chinese-flagged, 16 Japanese-flagged, 11 Federated States of Micronesia-flagged, and 2 Taiwan-flagged. The Japanese-flagged longliners land their catch in Japan; the other 39 vessels were domestically-based. In 2011, the Marshall Islands longline fleet had reported landings of principal market species of 259 mt of bigeye tuna, 99 mt of yellowfin tuna, 37 mt of blue marlin, 7 mt of black marlin, 4 mt of albacore tuna, and 3 mt of broadbill swordfish. Fresh chilled bigeye and yellowfin tuna is exported primarily to markets in the U.S., China and Canada, and frozen tuna and incidental market species are exported to China and marketed locally.
The Western Pacific Regional Fishery Management Council (WPRFMC) is one of eight regional councils established under the Magnuson-Stevens Fishery Conservation and Management Act (MSA) in 1976 to manage offshore fisheries. The WPRFMC's jurisdiction includes the US exclusive economic zone (EEZ) waters around the State of Hawaii; US Territories of American Samoa and Guam; the Commonwealth of the Northern Mariana Islands (CNMI); and the US Pacific remote island areas of Johnston, Midway, Palmyra and Wake Atolls; Baker, Howland and Jarvis Islands; and Kingman Reef. This area of nearly 1.5 million square miles is the size of the continental United States and constitutes about half of the entire US EEZ. It spans both sides of the equator and both sides of the dateline. The WPRFMC also manages domestic fisheries based in the US Pacific Islands that operate on the high seas.
The Hawaii longline fishery is managed under Western Pacific Regional Fishery Management Council’s (WPRFMC's) Pelagics Fisheries Ecosystem Plan. Through this plan, the WPRFMC has introduced logbooks, observers, vessel monitoring systems, fishing gear modifications and spatial management for the Hawaii longline fishery. Until relatively recently, the main driver for management of the Hawaii longline fishery has been bycatch and not fishery resources.
Of the twelve species of billfish, there are six species of Billfish in the Indian Ocean.
