Common Seal
The harbor (or harbour) seal (''Phoca vitulina''), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere. The most widely distributed species of pinnipeds, pinniped (walruses, eared seals, and true seals), they are found in coastal waters of the northern Atlantic Ocean, Atlantic, Pacific Oceans, Baltic Sea, Baltic and North Seas. Harbor seals are brown, silvery white, tan, or gray, with distinctive V-shaped nostrils. An adult can attain a length of 1.85 m (6.1 ft) and a mass of up to . Blubber under the seal's skin helps to maintain body temperature. Females outlive males (30–35 years versus 20–25 years). Harbor seals stick to familiar resting spots or haulout sites, generally rocky areas (although ice, sand, and mud may also be used) where they are protected from adverse weather conditions and predation, near a foraging area. Males may fight over mates under water and on land. Females bear a sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lismore, Scotland
Lismore ( gd, Lios Mòr, possibly meaning "great enclosure" or "garden") is an island of some in the Inner Hebrides of Scotland. The climate is damp and mild, with over of rain recorded annually. This fertile, low-lying island was once a major centre of Celtic Christianity, with a 6th-century monastery associated with Saint Moluag, and later became the seat of the medieval Bishop of Argyll. There are numerous ruined structures including a broch and two 13th-century castles. During the 19th century various new industries were introduced, including lime quarrying. During the early decades of the 20th century the population exceeded 1,000; but this was followed by a lengthy decline. Although resident numbers are now less than 200, there was a small increase from 2001 to 2011. About a third of the population were recorded as Gaelic-speaking at the former date. The modern economy is largely based on farming, fishing and tourism and the largest settlement is Achnacroish. Various sh ...

Phoca Vitulina Skeleton
''Phoca'' ( ) is a genus of the earless seals, within the family Phocidae, source of the French name for seal, 'phoque'. It now contains just two species, the common seal (or harbour seal) and the spotted seal (or largha seal). Several species formerly listed under this genus have been split into the genera ''Pusa'', '' Pagophilus'', and ''Histriophoca''. Until recently, ''Phoca largha'' has been considered a subspecies of ''Phoca vitulina'' but now is considered its own species. For this reason, the fossil history of the genus is unclear, and it has formerly been used as wastebasket taxon for a number of fossils of uncertain affinity. Species Currently there are two members: Former members of ''Phoca'': * ''Histriophoca fasciata'' (ribbon seal) * ''Pusa caspica'' (Caspian seal) * ''Pusa hispida'' (ringed seal) * ''Pusa sibirica'' (nerpa or Baikal seal) * ''Pagophilus groenlandica'' (harp seal) Mating ecology Both harbour and spotted seals are aquatically mating pinnipeds.

Marine Mammal Protection Act Of 1972
The Marine Mammal Protection Act (MMPA) was the first act of the United States Congress to call specifically for an ecosystem approach to wildlife management. Authority MMPA was signed into law on October 21, 1972, by President Richard Nixon and took effect 60 days later on December 21, 1972. It prohibits the "taking" of marine mammals, and enacts a moratorium on the import, export, and sale of any marine mammal, along with any marine mammal part or product within the United States. The Act defines "take" as "the act of hunting, killing, capture, and/or harassment of any marine mammal; or, the attempt at such." The MMPA defines harassment as "any act of pursuit, torment or annoyance which has the potential to either: a. injure a marine mammal in the wild, or b. disturb a marine mammal by causing disruption of behavioral patterns, which includes, but is not limited to, migration, breathing, nursing, breeding, feeding, or sheltering." The MMPA provides for enforcement of its pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conservation Of Seals Act 1970
The Conservation of Seals Act 1970 (c. 30) is an Act of the Parliament of the United Kingdom. It received royal assent on 29 May 1970. Criticism In 2007 there has been a call for better seal protection by Animal Concern and the Marine Conservation Society. The animal groups claim thousands seals are killed by fishing, fish farming and salmon angling industries. Animal welfare and conservation groups have called for new legislation to protect seals in Scottish waters. The Scottish Seals Forum is being asked to back calls to the Scottish Government for a comprehensive review of the Conservation of Seals Act 1970 after severe declines in common seal populations. See also * Animal welfare in the United Kingdom Animal welfare in the United Kingdom relates to the treatment of animals in fields such as agriculture, hunting, medical testing and the domestic ownership of animals. It is distinct from animal conservation. Laws The Animal Welfare Act 2006 i ... References Exter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bycatch
Bycatch (or by-catch), 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 (freshwater fish not saltwater fish) that are caught (either intentionally or unintentionally) but regarded as generally "undesirable" are referred to as "rough fish" (mainly US) and " coarse fish" (mainly UK). In 1997, the Organisation for Economic Co-operation and Development (OECD) defined bycatch as "total fishing mortality, excluding that accounted directly by the retained catch of target species". Bycatch contributes to fishery decline and is a mechanism of overfishing for unintentional catch. The average annual bycatch rate of pinnipeds and cetaceans in the US from 199 ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Fishery
Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life; or more commonly, the site where such enterprise takes place ( a.k.a. fishing ground). Commercial fisheries include wild fisheries and fish farms, both in freshwater waterbodies (about 10% of all catch) and the oceans (about 90%). About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem — causing declines in some populations. Because of their economic and social importance, fisheries are governed by complex fisheries management practices and legal regimes that vary widely across countries. Historically, fisheries were treated with a " first-come, first-served " approach, but recent threats by human overfishing and environmental issues have required increased regulation of fisheries to prevent conflict and increase profitable economic activity on the fishery.

Human
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedalism and exceptional cognitive skills due to a large and complex brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus ''Homo'', in common usage, it generally refers to ''Homo sapiens'', the only extant member. Anatomically moder ...

Phocine Distemper Virus
''Phocine morbillivirus'', formerly ''phocine distemper virus'' (PDV), is a paramyxovirus of the genus ''Morbillivirus'' that is pathogenic for pinniped species, particularly seals. Clinical signs include laboured breathing, fever and nervous symptoms. PDV was first identified in 1988 as the cause of death of 18,000 harbor seals (''Phoca vitulina'') and 300 grey seals (''Halichoerus grypus'') along the northern European coast. In 2002, an epizootic of PDV along the North Sea coast resulted in the deaths of 21,700 seals, estimated to be 51% of the population. Antibodies to PDV have been found in a number of carnivorous mammal species in the Western North Atlantic, including polar bears, and the Atlantic walrus. The suddenness of the emergence of PDV and related viruses in aquatic mammals has implicated environmental changes as the cause. Pollutants have been posited as contributors by interfering with the ability of animals to mount a defense against infection. Alternatively ...

Hokkaidō
is Japan's second largest island and comprises the largest and northernmost prefecture, making up its own region. The Tsugaru Strait separates Hokkaidō from Honshu; the two islands are connected by the undersea railway Seikan Tunnel. The largest city on Hokkaidō is its capital, Sapporo, which is also its only ordinance-designated city. Sakhalin lies about 43 kilometers (26 mi) to the north of Hokkaidō, and to the east and northeast are the Kuril Islands, which are administered by Russia, though the four most southerly are claimed by Japan. Hokkaidō was formerly known as ''Ezo'', ''Yezo'', ''Yeso'', or ''Yesso''. Nussbaum, Louis-Frédéric. (2005). "Hokkaidō" in Although there were Japanese settlers who ruled the southern tip of the island since the 16th century, Hokkaido was considered foreign territory that was inhabited by the indigenous people of the island, known as the Ainu people.
