The Antarctic is a polar region around Earth's South Pole, opposite the Arctic region around the North Pole.
Antarctic krill is a species of krill found in the Antarctic waters of the Southern Ocean. It is a small, swimming crustacean that lives in large schools, called swarms, sometimes reaching densities of 10,000–30,000 individual animals per cubic metre. It feeds directly on minute phytoplankton, thereby using the primary production energy that the phytoplankton originally derived from the sun in order to sustain their pelagic life cycle. It grows to a length of 6 centimetres (2.4 in), weighs up to 2 grams (0.071 oz), and can live for up to six years. It is a key species in the Antarctic ecosystem and in terms of biomass, is one of the most abundant animal species on the planet – approximately 500 million metric tons.
The Ross Sea is a deep bay of the Southern Ocean in Antarctica, between Victoria Land and Marie Byrd Land and within the Ross Embayment, and is the southernmost sea on Earth. It derives its name from the British explorer James Clark Ross who visited this area in 1841. To the west of the sea lies Ross Island and Victoria Land, to the east Roosevelt Island and Edward VII Peninsula in Marie Byrd Land, while the southernmost part is covered by the Ross Ice Shelf, and is about 200 miles (320 km) from the South Pole. Its boundaries and area have been defined by the New Zealand National Institute of Water and Atmospheric Research as having an area of 637,000 square kilometres (246,000 sq mi).
Krill are small and exclusively marine crustaceans of the order Euphausiacea, found in all the world's oceans. The name "krill" comes from the Norwegian word krill, meaning "small fry of fish", which is also often attributed to species of fish.
The Agreed Measures for the Conservation of Antarctic Fauna and Flora is a set of environmental protection measures which were accepted at the third Antarctic Treaty Consultative Meeting in Brussels in 1964. The Agreed Measures were formally in force as part of the Antarctic Treaty System from 1982 to 2011, when they were withdrawn as the principles were now entirely superseded by later agreements such as the 1991 Protocol on Environmental Protection to the Antarctic Treaty. The Agreed Measures were adopted in order to further international collaboration within the administration of the Antarctic Treaty System and promote the protection of natural Antarctic ecological systems while enabling scientific study and exploration.
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 Channel Islands National Marine Sanctuary is a sanctuary off the coast of Santa Barbara and Ventura counties in Southern California 350 miles south of San Francisco and 95 miles north of Los Angeles. It was designated in 1980 by the National Oceanic and Atmospheric Administration.
The Antarctic fur seal, is one of eight seals in the genus Arctocephalus, and one of nine fur seals in the subfamily Arctocephalinae. Despite what its name suggests, the Antarctic fur seal is mostly distributed in Subantarctic islands and its scientific name is thought to have come from the German vessel SMS Gazelle, which was the first to collect specimens of this species from Kerguelen Islands.
Marine protected areas (MPA) are protected areas of seas, oceans, estuaries or in the US, the Great Lakes. These marine areas can come in many forms ranging from wildlife refuges to research facilities. MPAs restrict human activity for a conservation purpose, typically to protect natural or cultural resources. Such marine resources are protected by local, state, territorial, native, regional, national, or international authorities and differ substantially among and between nations. This variation includes different limitations on development, fishing practices, fishing seasons and catch limits, moorings and bans on removing or disrupting marine life. In some situations, MPAs also provide revenue for countries, potentially equal to the income that they would have if they were to grant companies permissions to fish. The value of MPA to mobile species is unknown.
The krill fishery is the commercial fishery of krill, small shrimp-like marine animals that live in the oceans world-wide. The present estimate for the biomass of Antarctic krill is 379 million tonnes. The total global harvest of krill from all fisheries amounts to 150–200,000 tonnes annually, mainly Antarctic krill and North Pacific krill.
The South East Atlantic Fisheries Organisation (SEAFO) is an organization that maintains controls over fishing and fishing related acts in the Southeastern Atlantic Ocean.
Aker BioMarine is a Norwegian fishing and biotech company providing krill products through a fully documented and secured catch and process chain. Based in Oslo, Aker BioMarine is part of the Aker Group and the company also created Eco-Harvesting.
The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the world ocean, generally taken to be south of 60° S latitude and encircling Antarctica. With a size of 20,327,000 km2 (7,848,000 sq mi), it is regarded as the second-smallest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian oceans but larger than the Arctic Ocean. Since the 1980s, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem.
Dissostichus, the toothfish, is a genus of marine ray-finned fish belonging to the family Nototheniidae, the notothens or cod icefish. These fish are found in the Southern Hemisphere. Toothfish are marketed in the United States as Chilean sea bass or less frequently as white cod. "Chilean sea bass" is a marketing name coined in 1977 by Lee Lantz, a fish wholesaler who wanted a more attractive name for selling the Patagonian toothfish to Americans. In 1994, the U.S. Food and Drug Administration (FDA) accepted "Chilean sea bass" as an "alternative market name" for Patagonian toothfish. The toothfish was remarkably successful in the United States, Europe and Asia, and earned the nickname "white gold" within the market. Toothfish are vital to the ecological structure of Southern Ocean ecosystems. For this reason, on 4 September a national day is dedicated to the toothfish in South Georgia.
Barbara Wienecke is a senior research scientist with the Australian Antarctic Division. She is a seabird ecologist who uses satellite tracking to investigate seabird population dynamics and ecology. Wienecke has played a key role in enhancing the quality of, and overseeing the implementation of, a number of Antarctic Specially Protected Area management plans for wildlife concentrations in East Antarctica.
High seas fisheries management refers to the governance and regulation of fishing activities in areas beyond national jurisdiction, often referred to as the 'high seas'. The 1982 United Nations Convention on the Law of the Sea (UNCLOS) and the 1995 United Nations Fish Stock Agreement (UNFSA) provide the international legal framework for the regulation of fishing activities in areas beyond national jurisdiction. The United Nations Fish Stock Agreement delegates responsibility for conservation and management of fish stocks to regional fisheries management organizations (RFMOs) each governing a geographical area of the high seas.
Southern Indian Ocean Fisheries Agreement (SIOFA) is an international fisheries agreement between several nations signed in Rome on 7 July 2006 and entered into force on 21 June 2012. The purpose of the agreement is to ensure and promote the long-term conservation and sustainable use of the fishery resources in the area through cooperation among the member states.
The marine protected areas of South Africa are in an area of coastline or ocean within the exclusive economic zone (EEZ) of the Republic of South Africa that is protected in terms of specific legislation for the benefit of the environment and the people who live in and use it. An MPA is a place where marine life can thrive under less pressure than unprotected areas. They are like underwater parks, and this healthy environment can benefit neighbouring areas.
Denzil George Miller was a marine scientist and expert on Antarctic conservation, fisheries, policy and governance.
