CCGS W. E. Ricker
CCGS ''W.E. Ricker''CCGS stands for Canadian Coast Guard Ship was a Canadian Coast Guard offshore fisheries research vessel. The ship was originally constructed as the commercial fishing trawler ''Callistratus'', but was purchased by the Government of Canada in 1984 and converted to a fisheries research vessel and renamed ''W.E. Ricker''. The vessel entered service with the Department of Fisheries and Oceans in 1986 and was transferred to the Canadian Coast Guard in 1995 after the two fleets were amalgamated. The ship was assigned to the West Coast of Canada and was decommissioned on 14 March 2017. Design and description ''W.E. Ricker'' was of a commercial stern fishing trawler design and was long overall with a beam of and a draught of . The ship was propelled by one controllable pitch propeller driven by one Akasaka AH40 six-cylinder geared diesel engine, creating . ''W.E. Ricker'' also had one Perkins 2430 emergency generator. This gave the vessel a maximum speed of . Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina A marina (from Spanish , Portuguese and Italian : ''marina'', "coast" or "shore") is a dock or basin with moorings and supplies for yachts and small boats. A marina differs from a port in that a marina does not handle large passenger ships o ... berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research Vessels Of Canada
Research is "creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ships Of The Canadian Coast Guard
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were cont ...

Ship Breaking
Ship-breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships for either a source of parts Part, parts or PART may refer to: People *Armi Pärt (born 1991), Estonian handballer * Arvo Pärt (born 1935), Estonian classical composer *Brian Part (born 1962), American child actor *Dealtry Charles Part (1882–1961), sheriff (1926–1927) a ..., which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, Fatigue (material), metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycling, recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking i ...

Bill Ricker
William Edwin Ricker, (August 11, 1908 – September 8, 2001) is an important founder of fisheries science. He is best known for the Ricker model, which he developed in his studies of stock and recruitment in fisheries. The model can be used to predict the number of fish that will be present in a fishery. He also had an international standing as an entomologist and a scientific editor. He published 296 papers and books, 238 translations, and 148 scientific or literary manuscripts.Beamish et al. His 1958 publication, "Handbook of computation for biological statistics of fish populations" and later updates were the standard books on the subject for decades. Achievements Born in Waterdown, Ontario; Ricker was an authority in the taxonomy of stoneflies, and evolved an elegant classification which his fellow entomologists praised as "a thing of beauty and simplicity that made evolutionary sense". In fisheries, he researched issues centred on Canadian fisheries and how to manage t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rockfish
Rockfish is a common term for several species of fish, referring to their tendency to hide among rocks. The name rockfish is used for many kinds of fish used for food. This common name belongs to several groups that are not closely related, and can be arbitrary. Specific examples of fish termed rockfish include: *The family Sebastidae, marine fishes that inhabit oceans around the world. They may be included in the family Scorpaenidae. ** '' Sebastes'', Monterey Bay Aquarium. a commercially important genus of fish in the Sebastidae inhabiting mainly the North Pacific, but with a few species in the North Atlantic and southern oceans * '' Acanthoclinus'', a genus of fish from New Zealand * |
Turbot
The turbot (''Scophthalmus maximus'') is a relatively large species of flatfish in the family Scophthalmidae. It is a demersal fish native to marine or brackish waters of the Northeast Atlantic, Baltic Sea and the Mediterranean Sea. It is an important food fish. Turbot in the Black Sea have often been included in this species, but are now generally regarded as separate, the Black Sea turbot or kalkan (''S. maeoticus''). True turbot are not found in the Northwest Atlantic; the "turbot" of that region, which was involved in the so-called " Turbot War" between Canada and Spain, is the Greenland halibut or Greenland turbot (''Reinhardtius hippoglossoides''). Etymology The word comes from the Old French , which may be a derivative of the Latin ('spinning top') a possible reference to its shape. Another possible origin of the Old French word is from Old Swedish , from 'thorn' + 'stump, butt, flatfish', which may also be a reference to its shape (compare native English halibut). ...

North Pacific Hake
The North Pacific hake, Pacific hake, Pacific whiting, or jack salmon (''Merluccius productus'') is a ray-finned fish in the genus '' Merluccius'', found in the northeast Pacific Ocean from northern Vancouver Island to the northern part of the Gulf of California. It is a silver-gray fish with black speckling, growing to a length of . It is a migratory offshore fish and undergoes a daily vertical migration from the surface to the seabed at depths down to about . It is the object of an important commercial fishery off the West Coast of the United States, and annual quotas are used to prevent overfishing. Description Its length is about 3 ft (90 cm) and it can live up to 20 years. Its coloration is metallic silver-gray with black speckling and pure silvery white on the belly. The North Pacific hake has two dorsal fins and a truncated caudal fin. Its pectoral fin tips usually reach to or beyond the origin of its anal fin. The caudal fin is always concave. Reproduction ...

Diesel Fuel
Diesel fuel , also called diesel oil, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel. Therefore, diesel fuel needs good compression ignition characteristics. The most common type of diesel fuel is a specific fractional distillate of petroleum fuel oil, but alternatives that are not derived from petroleum, such as biodiesel, biomass to liquid (BTL) or gas to liquid (GTL) diesel are increasingly being developed and adopted. To distinguish these types, petroleum-derived diesel is sometimes called petrodiesel in some academic circles. In many countries, diesel fuel is standardised. For example, in the European Union, the standard for diesel fuel is EN 590. Diesel fuel has many colloquial names; most commonly, it is simply referred to as ''diesel''. In the United Kingdom, diesel fuel for on-road us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
