Largescale Sucker
The largescale sucker (''Catostomus macrocheilus'') is a species of sucker, a type of freshwater fish, found in western North America. Description It has a rounded snout with a downturned mouth on its underside (as opposed to a mouth at end of the head like most fish). It has large scales and narrow tail base (caudal peduncle). Juveniles are under in length. Adults can reach a length of and in parts of their range. Juveniles are mottled brown or olive green with dark spots and white to yellow belly. Adults are bronze to orange on top with lighter undersides. Distribution and habitat The largescale sucker is native to the Pacific Northwest, occurring from British Columbia south to Oregon. It is widespread in the Columbia River system. It occurs in the slower-moving portions of rivers and streams, and in lakes. Biology Largescale suckers spawn in the spring in shallow water over sandy areas of streams or the sandy or small gravel shoals of lakes. Females may produce up to 2 ...

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] |
Benthic
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from ancient Greek, βένθος (bénthos), meaning "the depths." Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at the shore line ( intert ...

Fish Of North America
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. M ...

Kalispell, Montana
Kalispell (, Montana Salish: Ql̓ispé, Kutenai language: kqayaqawakⱡuʔnam) is a city in, and the county seat of, Flathead County, Montana, United States. The 2020 census put Kalispell's population at 24,558. In Montana's northwest region, it is the largest city, and the commercial center, of the Kalispell Micropolitan Statistical Area. The name Kalispell is a Salish word meaning "flat land above the lake". History Using his own capital, Charles Edward Conrad, a businessman and banker from Fort Benton, Montana, formed the Kalispell Townsite Company with three other men. The townsite was quickly platted and lots began selling by the spring of 1891. Conrad built a large mansion in Kalispell in 1895. Kalispell was officially incorporated as a city in 1892. Since that time, the city has continued to grow in population, reaching 19,927 in 2010. As the largest city in northwest Montana, Kalispell serves as the county seat and commercial center of Flathead County. The city is ...

International Game Fish Association
The International Game Fish Association (''IGFA'') is the leading authority on angling pursuits and the keeper of the most current World Record fishing catches by fish categories. Fishermen who are sport fishers are careful to follow their stringent rules for fair play and line requirements in order to receive the honor of being listed in their annual "World Record Game Fishes" publication. The publication also gives fishing tips, and has an extensive fish identification guide. The IGFA is also an ardent proponent of aquatic habitat conservation, and cooperates with biologists all over the world. It is considered the world’s governing body for sport fishing. IGFA is headquartered in Dania Beach, Florida. Philosophy IGFA's objectives are founded on the beliefs that game fish species, related food fish, and their habitats are economic, social, recreational, and aesthetic assets which must be maintained, wisely used and perpetuated; and that the sport of angling is an importan ...

Rough Fish
Rough fish (or the slang trash fish or dirt fish) is a term used by some United States state agencies and anglers to describe fish that are less desirable to sport anglers within a defined region. The term usually refers to larger game fish species that are not commonly eaten, are too rare to be commonly encountered, or are not favorably sought by anglers for sporting purposes. Many of these species are actually very important in the commercial fishing industry, where they make up the bulk of commercial food fish catches in inland freshwater bodies.Carlander HB (1954''A history of fish and fishing in the upper Mississippi River''Upper Mississippi River Conservation Committee, University of California. Etymology The first reference to the term "rough" as applied to fish species is in the historical work ''A History of Fish and Fishing on the Upper Mississippi River'' by Carlander. To summarize: In the mid-to-late 19th century, commercial fishermen in the Central United States, par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American River Otter
The North American river otter (''Lontra canadensis''), also known as the northern river otter and river otter, is a semiaquatic mammal that only lives on the North American continent, along its waterways and coasts. An adult North American river otter can weigh between . The river otter is protected and insulated by a thick, water-repellent coat of fur. The North American river otter, a member of the subfamily Lutrinae in the weasel family (Mustelidae), is equally versatile in the water and on land. It establishes a burrow close to the water's edge in river, lake, swamp, coastal shoreline, tidal flat, or estuary ecosystems. The den typically has many tunnel openings, one of which generally allows the otter to enter and exit the body of water. Female North American river otters give birth in these burrows, producing litters of one to six young. North American river otters, like most predators, prey upon the most readily accessible species. Fish is a favored food among the otte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osprey
The osprey (''Pandion haliaetus''), , also called sea hawk, river hawk, and fish hawk, is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor reaching more than in length and across the wings. It is brown on the upperparts and predominantly greyish on the head and underparts. The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica, although in South America it occurs only as a non-breeding migrant. As its other common names suggest, the osprey's diet consists almost exclusively of fish. It possesses specialised physical characteristics and exhibits unique behaviour to assist in hunting and catching prey. As a result of these unique characteristics, it has been given its own taxonomic genus, ''Pandion'', and family, Pandionidae. Taxonomy The osprey was described by Carl Linnaeus under the name ''Falco haliaeetus'' i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diatom
A diatom ( Neo-Latin ''diatoma''), "a cutting through, a severance", from el, διάτομος, diátomos, "cut in half, divided equally" from el, διατέμνω, diatémno, "to cut in twain". is any member of a large group comprising several genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth's biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Depression, which was once made up of a system of fr ...

Zooplankton
Zooplankton are the animal component of the planktonic community ("zoo" comes from the Greek word for ''animal''). Plankton are aquatic organisms that are unable to swim effectively against currents, and consequently drift or are carried along by currents in the ocean, or by currents in seas, lakes or rivers. Zooplankton can be contrasted with phytoplankton, which are the plant component of the plankton community ("phyto" comes from the Greek word for ''plant''). Zooplankton are heterotrophic (other-feeding), whereas phytoplankton are autotrophic (self-feeding). This means zooplankton cannot manufacture their own food but must eat other plants or animals instead — in particular they eat phytoplankton. Zooplankton are generally larger than phytoplankton, most are microscopic, but some (such as jellyfish) are macroscopic and can be seen with the naked eye. Many protozoans (single-celled protists that prey on other microscopic life) are zooplankton, including zooflagellates, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
