Sebastes Babcocki
The redbanded rockfish (''Sebastes babcocki''), also known as the bandit, barber pole, flag rockfish, Spanish flag, Hollywood, convict, and canary, is a species of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae. It is found in the northern Pacific Ocean. Taxonomy The redbanded rockfish was first formally described as ''Sebastodes babcocki'' in 1915 by the American ichthyologist William Francis Thompson with the type locality given as Middleton Island, Alaska. Some authorities place this species in the subgenus ''Rosicola''. The specific name honours John Pease Babcock who was the first Commissioner of Fisheries for British Columbia, the organisation which published Francis' description. Description The redbanded rockfish reaches up to 64 centimeters in length. Its maximum recorded weight is 4.4 kilograms, and the mean weight is roughly 1.3 kilograms.Haigh, R. and P. Starr.

William Francis Thompson
William Francis Thompson (born St. Cloud, Minnesota 1888, died 7 November 1965) was an American ichthyologist and fisheries scientist. He researched the exploitation and management of the stocks of Pacific halibut for the fisheries department in British Columbia in the early 20th century, as well as the restoration Fraser River sockeye salmon run in the mid twentieth century. Thompson attended Stanford Univeristy for his doctoral research. His dissertation was titled, ''The biology of the halibut, with particular reference to marking experiments''. He completed the research for his dissertation in 1930 at the Hopkins Marine Station in Pacific Grove, California. Thompson was the director of the School of Fisheries at the University of Washington from 1934, and between 1937 and 1943 he was the director of the international Pacific Salmon Commission working in Canada and Alaska Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: '' ...

Aleutian Islands
The Aleutian Islands (; ; ale, Unangam Tanangin,”Land of the Aleuts", possibly from Chukchi language, Chukchi ''aliat'', "island"), also called the Aleut Islands or Aleutic Islands and known before 1867 as the Catherine Archipelago, are a chain of 14 large volcanic islands and 55 smaller islands. Most of the Aleutian Islands belong to the U.S. state of Alaska, but some belong to the Russian Federal subjects of Russia, federal subject of Kamchatka Krai. They form part of the Aleutian Arc in the Northern Pacific Ocean, occupying a land area of 6,821 sq mi (17,666 km2) and extending about westward from the Alaska Peninsula toward the Kamchatka Peninsula in Russia, and act as a border between the Bering Sea to the north and the Pacific Ocean to the south. Crossing 180th meridian, longitude 180°, at which point east and west longitude end, the archipelago contains both the westernmost part of the United States by longitude (Amatignak Island) and the easternmost by longitude ( ...

Commercial Fishing
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 also known as industrial fishing. The major fishing industries are not only owned by major corporations but by small families as well. In order to adapt to declining fish populations and increased demand, many commercial fishing operations have reduced the sustainability of their harvest by fishing further down the food chain. This raises concern for fishery managers and researchers, who highlight how further they say that for those reasons, the sustainability of the marine ecosystems could be in danger of collapsing. Commercial fishermen harvest a wide variety of animals. However, a very small number of species support the majority of the world ...

Peniculus Asinus
Panniculus, often incorrectly referred to as pannus, is a medical term describing a dense layer of fatty tissue, consisting of excess subcutaneous fat within the lower abdominal region. Panniculi can form after rapid weight loss, as seen with strict exercise plans—in this case, the abdominal fat is successfully reduced, but excess skin is left behind which hangs loosely over the area. It can be a result of obesity and can be mistaken for a tumor or hernia. Abdominal panniculus can be removed during abdominal panniculectomy, a type of abdominoplasty. A panniculus can also be the result of loose tissues after pregnancy or massive weight loss. See also * Intertrigo * Panniculus adiposus * Panniculus carnosus * Weber–Christian disease Weber–Christian disease, is a cutaneous condition characterized by recurrent subcutaneous nodules that heal with depression of the overlying skin. It is a type of panniculitis. It is a rare disease seen in females 30–60 years of age. It is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Copepod
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat (ecology), habitat. Some species are planktonic (inhabiting sea waters), some are benthos, benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as Ecological indicator, biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a Crustacean larvae#Nauplius, nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasitism
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), Disease vector, vector-transmitted paras ...
