Prosopium
''Prosopium'' is a genus of freshwater whitefishes found in North America and parts of eastern Russia. It contains three fairly widespread species: the round whitefish, the pygmy whitefish, and the mountain whitefish.

Prosopium Williamsoni
The mountain whitefish (''Prosopium williamsoni'') is one of the most widely distributed salmonid fish of western North America. It is found from the Mackenzie River drainage in Northwest Territories, Canada south through western Canada and the northwestern USA in the Pacific, Hudson Bay and upper Missouri River basins to the Truckee River drainage in Nevada and Sevier River drainage in Utah. Description The body shape is superficially similar to the cyprinids, although it is distinguished by having the adipose fin of salmonids. The body is slender and nearly cylindrical in cross section, generally silver with a dusky olive-green shade dorsally. The scales possess pigmented borders, which are especially defined on the posterior end. Mountain Whitefish possess a forked homocercal tail. The short head has a small mouth underneath the snout. The short dorsal fin has 12–13 rays, with 11–13 for the anal fin, 10–12 for the pelvic fins, and 14–18 for the pectoral fins. Siz ...

Prosopium Coulterii
The pygmy whitefish (''Prosopium coulterii'') is a freshwater whitefish of the genus ''Prosopium'' in the family Salmonidae. Found in the mountain streams and lakes in western North America, it also has isolated populations in Lake Superior and in Ekityki Lake, Chukchi Peninsula. Description The pygmy whitefish is a small herring-like fish with a long and cylindrical body by comparison to other whitefishes. Silvery in colour, it has a brownish back, and a whitish belly.Becker, 1983, pp. 369–371 Black spots on the side called "parr marks", which are present on young trout or "parrs", are present on the young of this species, and on adults in some Alaskan populations. Commonly ranging from in length, it is typically long, and reaches a maximum length of .Froese and Pauly, 2010 It is identified by its small size, and its large eye, which has a greater length than its blunt snout.Page and Burr, 1991, pp. 45–46 Its dorsal fin and pectoral fin are usually clear, and its tail is ...

Prosopium Cylindraceum
The round whitefish (''Prosopium cylindraceum'') is a freshwater species of fish that is found in lakes from Alaska to New England, including the Great Lakes. It has an olive-brown back with light silvery sides and underside and its length is generally between . They are bottom feeders, feeding mostly on invertebrates, such as crustaceans, insect larvae, and fish eggs. Some other fish species, like white sucker in turn eat their eggs. Lake trout, northern pike and burbot are natural predators. Other common names of the round whitefish are Menominee, pilot fish, frost fish, round-fish, and Menominee whitefish. The common name "round whitefish" is also sometimes used to describe ''Coregonus huntsmani'', a salmonid more commonly known as the Atlantic whitefish. While it was once common, numbers have been decreasing in the last century due to a number of possible causes. The round whitefish is now protected in some states, such as New York, under the Endangered Species Act f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosopium Spilonotus
The Bonneville whitefish (''Prosopium spilonotus'') is a salmonid fish endemic to Bear Lake on the Utah-Idaho border. It is one of three species of ''Prosopium'' endemic to Bear Lake, the other two being the Bear Lake whitefish and the Bonneville cisco. The species is listed as a ''Wildlife Species of Concern'' by the Utah Division of Wildlife Resources. In appearance, it is very similar to the closely related Bear Lake whitefish ''P. abyssicola''. Generally whitish in color, its nose is more tapered than that of the Bear Lake whitefish, and its scales are smaller. Younger fish, up to 10 inches (25 cm) long, have a pattern of spots which then fades. They have been reported to reach a length of 22 inches (56 cm) and an age of eight years. It generally inhabits mid-levels of the lake, where it primarily feeds on chironomid larvae and pupae, along with a variety of insects. The fish may also move into shallower waters, particularly during the winter months. Older fish also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosopium Abyssicola
The Bear Lake whitefish ''Prosopium abyssicola'' is a salmonid fish endemic to Bear Lake on the Utah-Idaho border. It is one of three species of Prosopium endemic to Bear Lake, the other two being the Bonneville whitefish and the Bonneville cisco. The species is listed as a ''Wildlife Species of Concern'' by the Utah Division of Wildlife Resources. Currently, Sheena Byrne, one of America's top Whitefish specialists, is specializing a research program to promote and protect the species, especially during their migratory season. In appearance it is very similar to the closely related Bonneville whitefish ''P. spilonotus''. Generally whitish in color, it has more of a "Roman nose" than the Bonneville whitefish, and larger scales. It never has spots, while young Bonneville whitefish (up to 10 inches) have a pattern of spots. The Bear Lake whitefish tends to be smaller as well, rarely longer than 9 inches, and with a maximum known length of 11 inches. It is primari ...

The species is listed as a ''Wildlife Species of Concern'' by the Utah Division of Wildlife Resources The Utah Division of Wildlife Resources is part of the Utah Department of Natural Resources for the state of Utah in the United States.

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 whi ...

Rosa Smith Eigenmann
Rosa Smith Eigenmann (October 7, 1858 – January 12, 1947) was an American ichthyologist (the branch of zoology devoted to the study of fish), as well as a writer, editor, former curator at the California Academy of Sciences, and the first librarian of the San Diego Society of Natural History. She "is considered the first woman ichthyologist in the United States." Eigenmann was also the first woman to become president of Indiana University's chapter of Sigma Xi, an honorary science society. She authored twelve published papers of her own between 1880 and 1893, and collaborated with her husband, Carl H. Eigenmann, as "Eigenmann & Eigenmann" on twenty-five additional works between 1888 and 1893. Together, they are credited with describing about 150 species of fishes. Early life and education Rosa Smith was born on October 7, 1858, in Monmouth, Illinois, the youngest of Lucretia (Gray) and Charles Kendall Smith's nine children. Smith's parents, originally from Vermont, had moved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Frédéric Girard
Charles Frédéric Girard (8 March 1822 – 29 January 1895) was a French biologist specializing in ichthyology and herpetology. Born in Mulhouse, France, he studied at the College of Neuchâtel, Switzerland, as a student of Louis Agassiz. In 1847, he accompanied Agassiz as his assistant to Harvard University. Three years later, Spencer Fullerton Baird called him to the Smithsonian Institution to work on its growing collection of North American reptiles, amphibians and fishes. He worked at the museum for the next ten years and published numerous papers, many in collaboration with Baird. In 1854, he was naturalized as a U.S. citizen. Besides his work at the Smithsonian, he managed to earn an M.D. from Georgetown University in Washington, D.C. in 1856. In 1859 he returned to France and was awarded the Cuvier Prize by the Institute of France for his work on the North American reptiles and fishes two years later. When the American Civil War broke out, he joined the Confeder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
