Guadalupe Bass
The Guadalupe bass (''Micropterus treculii'') is a rare species of fish endemic to the U.S. state of Texas, where it also is the official state fish. It is restricted to creeks and rivers (including the Guadalupe River, hence the name Guadalupe bass), and is listed as near threatened. Today, most fly fishermen and anglers practice catch-and-release techniques to improve fish populations. The Guadalupe bass is often difficult to distinguish from the smallmouth bass or spotted bass, and the fish is known to hybridize. Description and range Guadalupe bass, like most black bass, are lime to olive green in color, this particular species being lighter in shade usually in river specimens. They have a lateral line covered in mostly separate diamond-shaped or circular spots, which with age fade from black to olive. Also, many smaller diamond marks are scattered on the back, which are less distinguished than the ones on the lateral line. They have a rectangular tooth patch on the tongue ...

Marie Firmin Bocourt
Marie Firmin Bocourt (19 April 1819 – 4 February 1904) was a French zoologist and artist. As a young man, he worked as a preparateur for the zoologist Gabriel Bibron (1805–1848), later serving as a museum artist. In 1861, he was sent to Thailand (then called Siam), where he explored the fauna and brought back an important collection of specimens. He collaborated with Auguste Duméril (1812–1870) on a series called ''Mission scientifique au Mexique et dans l'Amérique Centrale'', a result of Bocourt's scientific expedition to Mexico and Central America in 1864–1866, in one part during the French Intervention in Mexico led by Napoleon III. Auguste Duméril died in 1870, and the project was continued by Bocourt with assistance from Léon Vaillant (1834–1914), François Mocquard (1834–1917) and Fernand Angel (1881–1950). With Vaillant, he published a study on fishes, "''Études sur les poissons'' ", that was included in ''Mission scientifique au Mexique et dans l'Améri ...

Endemism
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 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Guadalupe River (Texas)
The Guadalupe River (), () runs from Kerr County, Texas, to San Antonio Bay on the Gulf of Mexico, with an average temperature of . It is a popular destination for rafting, fly fishing, and canoeing. Larger cities along it include Kerrville, New Braunfels, Seguin, Gonzales, Cuero, and Victoria. It has several dams along its length, the most notable of which, Canyon Dam, forms Canyon Lake northwest of New Braunfels. Course The upper part, in the Texas Hill Country, is a smaller, faster stream with limestone banks and shaded by pecan and bald cypress trees. It is formed by two main tributary forks, the North Fork and South Fork Guadalupe Rivers. It is popular as a tubing destination where recreational users often float down it on inflated tire inner tubes during the spring and summer months. East of Boerne, on the border of Kendall County and Comal County, it flows through Guadalupe River State Park, one of the more popular tubing areas along it. The lower part begins at ...

Near Threatened
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened. IUCN Categories and Criteria version 2.3 Before 2001, the IUCN used the version 2.3 Categories and Criteria ...

Spotted Bass
The spotted bass (''Micropterus punctulatus''), also called spotty, or spots in various fishing communities, is a species of North American freshwater fish belonging to the sunfish family (Centrarchidae) of the order Perciformes. It is noted for the rows of dark spots below the lateral line, which give it its common name. One of the black basses, it is native to the Mississippi River basin and across the Gulf states, from central Texas through the Florida panhandle. Its native range extends into the western Mid-Atlantic states and it has been introduced into western North Carolina and Virginia. It has also been introduced to southern Africa, where it has become established in some isolated waters as an invasive species. Spotted bass can reach an overall length of almost , and weights of up to . It can live to an age of at least seven years. Preferring cool and warm mountain streams and reservoirs with rocky bottoms, the spotted bass feeds on insects, crustaceans, frogs ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ...

IGFA
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 important ...

Lake Travis
Lake Travis is a reservoir on the Colorado River in central Texas in the United States. Serving principally as a flood-control reservoir, Lake Travis' historical minimum to maximum water height change is nearly 100 feet. In 2018 alone, it saw a 20-foot depth increase within a single 24-hour period of time. With 30 square miles of surface area, Lake Travis has the largest storage capacity of the seven reservoirs known as the Highland Lakes, and stretches 65 miles (105 km) upriver from western Travis County (near Lago Vista, Texas) in a highly serpentine course into southern Burnet County to Max Starcke Dam, southwest of the town of Marble Falls. Besides being used for flood control and as a water supply, the lake is also used for electrical power generation and recreation. The Pedernales River, a major tributary of the Colorado River, flows into the lake from southwestern Travis County. History Creation The reservoir was formed in 1942 by the construction of Man ...
