Collapse Of The Atlantic Northwest Cod Fishery
In 1992, Atlantic cod, Northern cod biomass (ecology), populations fell to 1% of historical levels, in large part from decades of overfishing. The Canadian Minister of Fisheries and Oceans (Canada), Federal Minister of Fisheries and Oceans, John Crosbie, declared a moratorium (law), moratorium on the Northern Cod Cod fishery, fishery, which had primarily shaped the lives and communities of Canada's eastern coast for 500 years. A significant factor contributing to the depletion of the cod stocks off Newfoundland (island), Newfoundland's shores was the introduction of equipment and technology that increased landed fish volume. From the 1950s onwards, new technology allowed fishers to trawl a larger area more deeply and for longer, with the catches peaking in the 1970s and 1980s. Cod stocks were depleted at a faster rate than could be replenished. The trawlers also caught enormous amounts of non-commercial fish, which were economically unimportant but Keystone species, very importan ...

Capelin
The capelin or caplin (''Mallotus villosus'') is a small forage fish of the smelt family found in the North Atlantic, North Pacific and Arctic oceans. In summer, it grazes on dense swarms of plankton at the edge of the ice shelf. Larger capelin also eat a great deal of krill and other crustaceans. Among others, whales, seals, Atlantic cod, Atlantic mackerel, squid and seabirds prey on capelin, in particular during the spawning season while the capelin migrate south. Capelin spawn on sand and gravel bottoms or sandy beaches at the age of two to six years. When spawning on beaches, capelin have an extremely high post-spawning mortality rate which, for males, is close to 100%. Males reach in length, while females are up to long. They are olive-coloured dorsally, shading to silver on sides. Males have a translucent ridge on both sides of their bodies. The ventral aspects of the males iridesce reddish at the time of spawn. The closest relative of the capelin appears to have be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fisheries-induced Evolution
Fisheries-induced evolution (FIE) is the microevolution of an exploited aquatic organism's population, brought on through the artificial selection for biological traits by fishing practices (fishing techniques and fisheries management). Fishing, of any severity or effort, will impose an additional layer of mortality to the natural population equilibrium and will be selective to certain genetic traits within that organism's gene pool. This removal of selected traits fundamentally changes the population gene frequency, resulting in the artificially induced microevolution by the proxy of the survival of untargeted fish and their propagation of heritable biological characteristics. This artificial selection often counters natural life-history pattern for many species, such as causing early sexual maturation, diminished sizes for matured fish, and reduced fecundity in the form of smaller egg size, lower sperm counts and viability during reproductive events. These effects can have pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Total Allowable Catch
The Common Fisheries Policy (CFP) is the fisheries policy of the European Union (EU). It sets quotas for which member states are allowed to catch each type of fish, as well as encouraging the fishing industry by various market interventions. In 2004 it had a budget of €931 million, approximately 0.75% of the EU budget. When it came into force in 2009, the Treaty of Lisbon formally enshrined fisheries conservation policy as one of the handful of "exclusive competences" reserved for the European Union, to be decided by Qualified Majority Voting. However, general fisheries policy remains a "shared competence" of the Union and its member states. Decisions are now made by the Council of the European Union, and the European Parliament acting together under the co-decision procedure. The Common Fisheries Policy was created to manage fish stock for the European Union as a whole. Article 38 of the 1957 Treaty of Rome, which created the European Communities (now European Union ...

Ecological Applications
The Ecological Society of America (ESA) is a professional organization of ecological scientists. Based in the United States and founded in 1915, ESA publications include peer-reviewed journals, newsletters, fact sheets, and teaching resources. It holds an annual meeting at different locations in the USA and Canada. In addition to its publications and annual meeting, ESA is engaged in public policy, science, education, and diversity issues. ESA's 9,000 members are researchers, educators, natural resource managers, and students in over 90 countries. Members work on a wide range of topics, from agroecology to marine diversity, and explore the relationships between organisms and their past, present, and future environments. the society has 32 topical sections, six regional chapters, and ten committees. History The first discussions on the formation of the society took place in 1914 in the lobby of the Hotel Walton in Philadelphia, Pennsylvania, at a meeting of animal and plant e ...

UNCLOS
The United Nations Convention on the Law of the Sea (UNCLOS), also called the Law of the Sea Convention or the Law of the Sea Treaty, is an international treaty that establishes a legal framework for all marine and maritime activities. , 169 sovereign states and the European Union are parties, including all major powers except the United States. The convention resulted from the third United Nations Conference on the Law of the Sea (UNCLOS III), which took place between 1973 and 1982. UNCLOS replaced the four treaties of the 1958 Convention on the High Seas. UNCLOS came into force in 1994, a year after Guyana became the 60th nation to ratify the treaty. In 2023, agreement was reached on a High Seas Treaty to be added as an instrument of the convention, to protect ocean life in international waters. This would provide measures including Marine Protected Areas and environmental impact assessments. While the secretary-general of the United Nations receives instruments of ratificat ...

Exclusive Economic Zone
An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has exclusive rights regarding the exploration and use of marine natural resource, resources, including energy production from water and wind. It stretches from the outer limit of the territorial sea (22.224 kilometres or 12 nautical miles from the baseline) out 370.4 kilometres (or 200 nautical miles) from the coast of the state in question. It is also referred to as a maritime continental margin and, in colloquial usage, may include the continental shelf. The term does not include either the Territorial waters#Territorial sea, territorial sea or the continental shelf beyond the 200 nautical mile limit. The difference between the territorial sea and the exclusive economic zone is that the first confers full sovereignty over the waters, whereas the second is merely a "sovereign right" which refers to the coastal state's righ ...

Fishing Trawlers
A fishing trawler is a commercial fishing vessel designed to operate Trawling, fishing trawls. Trawling is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers. Trawls are fishing nets that are pulled along the bottom of the sea or in midwater at a specified depth. A trawler may also operate two or more trawl nets simultaneously (double-rig and multi-rig). There are many variants of trawling gear. They vary according to local traditions, bottom conditions, and how large and powerful the trawling boats are. A trawling boat can be a small open boat with only 30 horsepower (22 kW) or a large factory ship with 10,000 horsepower (7457 kW). Trawl variants include beam trawls, large-opening midwater trawls, and large bottom trawls, such as "rock hoppers" that are rigged with heavy rubber wheels that let the net crawl over rocky bottom. History The 17th century saw the development of an early type of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Newfoundland Act
The Newfoundland Act was an act of the Parliament of the United Kingdom that confirmed and gave effect to the Terms of Union agreed to between the then-separate Dominions of Canada and Newfoundland on 23 March 1949. It was originally titled the British North America Act 1949, but was renamed in Canada on the patriation of the Canadian Constitution from the United Kingdom in 1982. In exchange for Newfoundland becoming a province, the Canadian government took over the Newfoundland Railway, Newfoundland Airport (now Gander International Airport), public broadcasting, telegraph services and other services that fell under federal control. The federal government assumed responsibility for Newfoundland's debt.Dominion Delegation, ''St. John's Telegram'', 11 December 2005 Newfoundland was also given statutory subsidies, a special subsidy of $1.1 million, the right to enter into tax rental agreements with the federal government and an additional transitional grant of $3.5 million, di ...

Atlantic Canada
Atlantic Canada, also called the Atlantic provinces (), is the list of regions of Canada, region of Eastern Canada comprising four provinces: New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island. As of 2021, the landmass of the four Atlantic provinces was approximately , and had a population of over 2.4 million people. The term ''Atlantic Canada'' was popularized following the admission of Newfoundland as a Canadian province in 1949. The province of Newfoundland and Labrador is not included in the Maritimes, another significant regional term, but ''is'' included in Atlantic Canada. History The Atlantic Provinces are the historical territories of the Mi'kmaq, Naskapi, Beothuk and Nunatsiavut peoples. The people of Nunatsiavut are the Labrador Inuit (Labradormiut), who are descended from the Thule people. Exploration and settlement Leif Erikson and other members of his family began exploring the North American coast in 986 CE. Leif landed in three pla ...
