Freshwater Whitefish
The freshwater whitefish are fishes of the subfamily Coregoninae, which contains whitefishes (both freshwater and anadromous) and ciscoes, and is one of three subfamilies in the salmon family Salmonidae. Apart from the subfamily Coregoninae, the family Salmonidae includes the salmon, trout, and char species of the subfamily Salmoninae, and grayling species of the subfamily Thymallinae. Freshwater whitefish are distributed mainly in relatively cool waters throughout the northern parts of the Northern Hemisphere. The Coregoninae subfamily consists of three nominal genera: *''Coregonus'' Linnaeus, 1758 – whitefishes and ciscoes, which according to some authors number more than 60 species. There are differing opinions on the classification of some species within the genus and the overall number of species. Some species in Arctic regions of Asia and North America forage in marine waters. *''Prosopium'' Jordan, 1878 – round whitefishes, which includes six species, three of which ...

Coregonus Albula
''Coregonus albula'', known as the vendace or as the European cisco, is a species of freshwater whitefish in the family Salmonidae. It is found in lakes in northern Europe, especially Finland, Latvia, Lithuania, Sweden, Russia and Estonia, and in some lakes of Norway, the United Kingdom, northern Germany, and Poland. It is also found in diluted brackish water in the Gulfs of Finland and Bothnia, both of which are in the Baltic Sea. The length of an adult is normally about . The maximum age is about ten years. The vendace is traditionally the most important target of freshwater fisheries in parts of Fennoscandia and Russia. Vendace roe is considered a delicacy, which has been granted a PDO status in the Swedish Bothnian Bay archipelago (Kalix löjrom). Description The vendace is a slim, streamlined fish with an adipose fin - an additional small fin on the back between the dorsal fin and the tail (caudal fin), as is typical of the salmon family. Its lower jaw is longer than the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coregonus Vandesius
''Coregonus vandesius'', the vendace , is a freshwater whitefish found in the United Kingdom. Population surveys since the 1960s have revealed a steady decline and the fish is no longer present in some of its previous haunts but is still present in Bassenthwaite Lake and Derwent Water. The main threats it faces are eutrophication and the introduction of alien species of fish which eat its eggs and fry. The International Union for Conservation of Nature has rated its conservation status as "endangered". Taxonomy Most authorities now consider ''Coregonus vandesius'' to be a subjective synonym of ''Coregonus albula'', which is a more widespread North European freshwater whitefish species. Both taxa are also known by the common name vendace. The status however remains controversial, and FishBase still lists ''C. vandesius'' as a separate species, reflecting the recent treatment of the European freshwater fish fauna by Kottelat & Freyhof (2007). Another synonym of British ''C. vandes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Vendace (SS-430)
The ''Balao'' class was a successful design of United States Navy submarine used during World War II, and with 120 boats completed, the largest class of submarines in the United States Navy. An improvement on the earlier , the boats had slight internal differences. The most significant improvement was the use of thicker, higher yield strength steel in the pressure hull skins and frames, which increased their test depth to . ''Tang'' actually achieved a depth of during a test dive, and exceeded that test depth when taking on water in the forward torpedo room while evading a destroyer. Design The ''Balao''s were similar to the ''Gato''s, except they were modified to increase test depth from to . In late 1941, two of the Navy's leading submarine designers, Captain Andrew McKee and Commander Armand Morgan, met to explore increasing diving depth in a redesigned ''Gato''. A switch to a new High-Tensile Steel (HTS) alloy, combined with an increase in hull thickness from to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
