Theodore Gill
Theodore Nicholas Gill (March 21, 1837 – September 25, 1914) was an American ichthyologist, mammalogist, malacologist and librarian. Career Born and educated in New York City under private tutors, Gill early showed interest in natural history. He was associated with J. Carson Brevoort in the arrangement of the latter's entomological and ichthyological collections before going to Washington D.C. in 1863 to work at the Smithsonian Institution. He catalogued mammals, fishes and mollusks most particularly although maintaining proficiency in other orders of animals. He was librarian at the Smithsonian and also senior assistant to the Library of Congress. He was elected as a member of the American Philosophical Society in 1867. Gill was professor of zoology at George Washington University. He was also a member of the Megatherium Club at the Smithsonian Institution in Washington, D.C. Fellow members frequently mocked him for his vanity. He was president of the American Associati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gadidae
The Gadidae are a family of marine fish, included in the order Gadiformes, known as the cods, codfishes, or true cods. It contains several commercially important fishes, including the cod, haddock, whiting, and pollock. Most gadid species are found in temperate waters of the Northern Hemisphere, but several range into subtropical, subarctic, and Arctic oceans, and a single (southern blue whiting) is found in the Southern Hemisphere. They are generally medium-sized fish, and are distinguished by the presence of three dorsal fins on the back and two anal fins on the underside. Most species have barbels on their chins, which they use while browsing on the sea floor. Gadids are carnivorous, feeding on smaller fish and crustaceans. Gadids are highly prolific, producing several million eggs at each spawning. This contributes to their high population numbers, which, in turn, makes commercial fishing relatively easy. Concepts differ about the contents of the family Gadidae. The syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microgadus Proximus
''Microgadus proximus'', also commonly known as Pacific tomcod, is a type of cod fish found in North American coastal waters from the southeastern Bering Sea to central California California is a U.S. state, state in the Western United States, located along the West Coast of the United States, Pacific Coast.

Their diet of the Pacific tomcod includes anchovies, shrimp, worms, and other small marine invertebrates. Pacific tomcod are occasionally taken by recreational anglers. This is usually incidental to fishing for other species of fish as they are relatively small in size.

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 Confederate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microgadus Tomcod
''Microgadus tomcod'', also commonly known as frostfish, Atlantic tomcod or winter cod, is a type of cod found in North American coastal waters from the Gulf of St. Lawrence, St. Lawrence River and northern Newfoundland, south to Virginia. The fishing season of the tomcod varies by location—one known example is the Sainte-Anne River in Quebec, where its season is from late-December to mid-February. A bimonitoring program tracked hormone levels of Atlantic tomcod caught near Miramichi and Kouchibouguac in 1993 and 1994, demonstrating that the preparatory period for spawning began in September with maximal steroid levels in November, and spawning took place from late December to January. The town of Sainte-Anne-de-la-Pérade is notable for its fishing village built on the frozen waters of the Ste-Anne, playing host to the scores of fishermen visiting the town to fish for the species. After General Electric dumped polychlorinated biphenyls (PCBs) in the Hudson River from 1947 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Julius Walbaum
Johann Julius Walbaum (30 June 1724 – 21 August 1799) was a German physician, naturalist and fauna taxonomist. Works As an ichthyologist, he was the first to describe many previously unknown fish species from remote parts of the globe, such as the Great Barracuda (''Sphyraena barracuda''), the Chum salmon (''Oncorhynchus keta'') from the Kamchatka River in Siberia, and the curimatá-pacú (''Prochilodus marggravii'') from the São Francisco River in Brazil. He was also the first to observe gloves as a preventative against infection in medical surgery. In 1758, the gloves he observed were made from the cecum of the sheep, rather than rubber, which had not yet been discovered. Legacy The Natural History Museum in Lübeck, opened in 1893, was based on Walbaum's extensive scientific collection, which was lost during the Second World War World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945.
