Little Kern Golden Trout
The Little Kern golden trout (''Oncorhynchus mykiss whitei'') is a brightly colored subspecies of rainbow trout native to the main stem and tributaries of the Little Kern River in Tulare County, California. Together with the California golden trout (the state fish of California) and the Kern River rainbow trout, the Little Kern golden trout forms what is sometimes referred to as the "golden trout complex" of the Kern River basin. Taxonomic history The evolutionary relationships between salmonoids is a matter of ongoing discovery, and there are different opinions about how specific populations should be grouped and named. The same can be said for the Little Kern golden trout, which has experienced several classification revisions since its first formal description. The Little Kern golden trout was first described as ''Salmo Whitei'' in 1906 by the biologist Barton Warren Evermann in his book ''...The Golden Trout of the Southern High Sierras''. Everman had been sent to the Ke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barton Warren Evermann
Barton Warren Evermann (October 24, 1853 – September 27, 1932) was an American ichthyologist. Early life and education Evermann was born in Monroe County, Iowa in 1853. His family moved to Indiana while he was still a child and it was there that he grew up, completed his education, and married. Evermann graduated from Indiana University in 1886. Career For 10 years, he served as teacher and superintendent of schools in Indiana and California. While teaching in Carroll County, Indiana Evermann met fellow teacher Meadie Hawkins.

California Department Of Fish And Game
The California Department of Fish and Wildlife (CDFW), formerly known as the California Department of Fish and Game (CDFG), is a state agency under the California Natural Resources Agency. The Department of Fish and Wildlife manages and protects the state's wildlife, wildflowers, trees, mushrooms, algae (kelp) and native habitats (ecosystems). The department is responsible for regulatory enforcement and management of related recreational, commercial, scientific, and educational uses. The department also prevents illegal poaching. History The Game Act was passed in 1852 by the California State Legislature and signed into law by Governor John Bigler. The Game Act closed seasons in 12 counties for quail, partridge, mallard and wood ducks, elk, deer, and antelope. A second legislative action enacted the same year protected salmon runs. In 1854, the Legislature extended the act to include all counties of California. In 1860, protection controls were extended for trout. Lake Merrit ...

Endangered Fauna Of California
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Fish
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 643 endangered fish species. 4.2% of all evaluated fish species are listed as endangered. The IUCN also lists ten fish subspecies as endangered. Of the subpopulations of fishes evaluated by the IUCN, 24 species subpopulations have been assessed as endangered. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by ''critically endangered'' species, which meet the quantitative criteria for endangered species. Critically endangered fishes are listed separately. There are 1098 fish species which are endangered or critically endangered. Additionally 3191 fish species (21% of those evaluated) are listed as ''data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have smal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Natural History Of Tulare County, California
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Soc ...

Freshwater Fish Of The United States
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh wa ...

Fish Of The Western United States
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. Most f ...

Fauna Of The Sierra Nevada (United States)
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of California
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broodstock
Broodstock, or broodfish, are a group of mature individuals used in aquaculture for breeding purposes. Broodstock can be a population of animals maintained in captivity as a source of replacement for, or enhancement of, seed and fry numbers.Waples, R.S., and C. Do. 1994. Genetic risk associated with supplementation of Pacific salmonids: Captive broodstock programs. Canadian Journal of Fisheries and Aquatic Science,51(1), 310–329. These are generally kept in ponds or tanks in which environmental conditions such as photoperiod, temperature and pH are controlled. Such populations often undergo conditioning to ensure maximum fry output. Broodstock can also be sourced from wild populations where they are harvested and held in maturation tanks before their seed is collected for grow-out to market sizeFast, A. W. (1994).

Kernville, California
Kernville is a census-designated place (CDP) in the southern Sierra Nevada, in Kern County, California, United States. Kernville is located northeast of Bakersfield, at an elevation of . The population was 1,395 at the 2010 census, down from 1,736 at the 2000 census. History The Kern River was named after artist and topographer Edward Kern, who accompanied John C. Fremont on his 1845 expedition. They camped at what was a fork of two rivers, now the middle of Lake Isabella. An 1858 gold rush led to the formation of a town briefly called Rogersville, then Williamsburg, which was in 1863 renamed Whiskey Flat after a bar opened. In 1864, the town was renamed Kernville. After decades of planning, the Isabella Dam project began in 1948. As a result, Kernville was relocated upstream to its present location at the tip of the northeast fork of the man-made lake, along with certain historic buildings. Downtown visibly retains Kernville's gold rush and Old West roots, attracting tourist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
