Dorosoma Anale
''Dorosoma'' is a genus that contains five species of shads, within the family Dorosomatidae. The five species are native to the North and/or Central America, and are mostly known from fresh water, though some may reside in the waters of estuaries and bays. The American gizzard shad is important to the food web in America due to being a source of game fish food. They also have a long history of stock introductions that can lead to disruptions to the food web.

Dorosoma Cepedianum
The American gizzard shad (''Dorosoma cepedianum''), also known as the mud shad, is a member of the herring family of fish and is native to large swaths of fresh and brackish waters in the United States of America, as well as portions of Quebec, Canada, and Mexico. The adult has a deep body, with a silvery-green coloration above fading to plain silver below. The gizzard shad commonly resides in freshwater lakes, reservoirs, rivers, and streams but can also reside in brackish waters, as it does on the Atlantic coast of the United States. Their range is across most of the continental United States, although they typically go no further north than New York and no further west than New Mexico. They are a large part of many of the ecosystems they inhabit and can drive changes in phyto- and zooplankton, thereby indirectly affecting other planktivorous fishes. The gizzard shad has been widely used as a food source for game fish, with varied success in management and effectiveness. Et ...

Dorosoma Petenense
The threadfin shad (''Dorosoma petenense'') is a small pelagic freshwater forage fish common in lakes, large streams and reservoirs of the Southeastern United States. Like the American gizzard shad, the threadfin shad has an elongated dorsal fin, but unlike the gizzard shad, its mouth is more terminal without a projecting upper jaw. The fins of threadfin shad often have a yellowish color, especially the caudal fin. The back is grey to blue with a dark spot on the shoulder. ''D. petenense'' is more often found in moving water, and is rarely found deep in the water column. It occurs in large schools, sometimes with gizzard shad, and can be seen on the surface at dawn and dusk. The threadfin shad may reach lengths of , but only rarely. This fish is very sensitive to changes in temperature and dissolved oxygen, and die-offs are frequent in late summer and fall, especially when water temperature drops to 42 °F. The threadfin shad is a favorite food for many game fishes, includin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of North America
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish w ...

He was born in Colorado Springs, earned his bachelor's degree at University of California, Berkeley in 1938, a master's degree at the University of Michigan in 1943, and a doctorate, Ph.D. at the University of Michigan in 1944. He received tenure at the University of Michigan in 1954. Together with W. L. Minckley, he discovered a new species of platyfish, ''Xiphophorus gordoni'', that they named in honor of Dr Myron Gordon (biologist), Myron Gordon.

Carl Leavitt Hubbs
Carl Leavitt Hubbs (October 19, 1894 – June 30, 1979) was an American ichthyologist. Biography Early life Carl Leavitt Hubbs was born in Williams, Arizona, to Charles Leavitt and Elizabeth () Hubbs. His father had a wide variety of jobs (farmer, iron mine owner, newspaper owner). The family moved several times before settling in San Diego where he got his first taste of natural history. After his parents divorced in 1907, he lived with his mother, who opened a private school in Redondo Beach, California. His maternal grandmother Jane Goble Goss, one of the first female doctors, showed Hubbs how to harvest shellfish and other sea creatures. One of his teachers, impressed by Hubbs's abilities in science, recommended that he study chemistry at the University of Berkeley. The family moved once more to Los Angeles. In Los Angeles, George Bliss Culver, one of the many volunteers of David Starr Jordan, encouraged Hubbs to abandon his study of birds and instead to study fish, part ...

Albert Günther
Albert Karl Ludwig Gotthilf Günther , also Albert Charles Lewis Gotthilf Günther (3October 18301February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described. Early life and career Günther was born in Esslingen in Swabia ( Württemberg). His father was a ''Stiftungs-Commissar'' in Esslingen and his mother was Eleonora Nagel. He initially schooled at the Stuttgart Gymnasium. His family wished him to train for the ministry of the Lutheran Church for which he moved to the University of Tübingen. A brother shifted from theology to medicine, and he, too, turned to science and medicine at Tübingen in 1852. His first work was "''Ueber den Puppenzustand eines Distoma''" (On the pupal state of ''Distoma'').

Constantine Samuel Rafinesque
Constantine Samuel Rafinesque-Schmaltz (; 22 October 178318 September 1840) was a French early 19th-century polymath born near Constantinople in the Ottoman Empire and self-educated in France. He traveled as a young man in the United States, ultimately settling in Ohio in 1815, where he made notable contributions to botany, zoology, and the study of Mound Builders, prehistoric earthworks in North America. He also contributed to the study of ancient Mesoamerican languages, Mesoamerican linguistics, in addition to work he had already completed in Europe. Rafinesque was an eccentric and erratic genius. He was an autodidact, who excelled in various fields of knowledge, as a zoologist, botanist, writer and Polyglot (person), polyglot. He wrote prolifically on such diverse topics as anthropology, biology, geology, and linguistics, but was honored in none of these fields during his lifetime. Indeed, he was an outcast in the American scientific community and his submissions were automati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Alexandre Lesueur (; 1 January 1778 in Le Havre – 12 December 1846 in Le Havre) was a French Natural history, naturalist, artist, and explorer. He was a prolific natural-history collector, gathering many type specimens in Australia, Southeast Asia, and North America, and was also responsible for describing numerous species, including the spiny softshell turtle (''Apalone spinifera''), smooth softshell turtle (''Apalone mutica, A. mutica''), and common map turtle (''Graptemys geographica'').

Seth Eugene Meek
Seth Eugene Meek (April 1, 1859, Hicksville, Ohio – July 6, 1914, Chicago) was an American ichthyologist at the Field Museum of Natural History in Chicago. He was the first compiler of a book on Mexican freshwater fishes. Together with his assistant, Samuel F. Hildebrand, he produced the first book on the freshwater fishes of Panama. He often collaborated with Charles H. Gilbert, and in 1884 on a collecting trip through the Ozarks, they discovered a new species, '' Etheostoma nianguae'', which only lives in the Osage River basin. Also with them on that excursion was David Starr Jordan, considered the father of modern ichthyology. After the Ozarks trip, Meek accepted the post of professor of biology and geology at Arkansas Industrial University (now the University of Arkansas). Taxon named after him *The American halfbeak was named in his honor ''Hyporhamphus meeki'', as were: *the Mezquital pupfish (''Cyprinodon meeki'') *The firemouth cichlid (''Thorichthys meeki'') * ...
