The golden trout is found in high altitude fresh bodies of water in the western area of the United States. Specifically, this species can be found in Wyoming, Idaho, Washington, and most abundantly in California, where it was first discovered.
Biogeographic Regions: nearctic (Native )
The diet of the golden trout consists mainly of surface water-dwelling insects, principally small ones such as caddisflies and midges. Small crustaceans such as tiny fresh water shrimp as well as some terrestrial insects contribute to the diet as well. However, small insects, either in larvae or fully developed form, floating on the surface compose most of the natural food of this species. To feed, the trout opens its gills and hinged mouth and inhales its prey whole in the water. The water is then pushed back out of the gills, acting much like a filter, leaving only the food in its mouth. The primary feeding season is from May through September, because there is a scarcity of insects found during the colder season.
The main benefit is that goldens attract fishers and are prime food fish, either pan sauted or smoked. It is of little interest to tourists unless the tourists are fishing fanatics eager to catch a rare golden while enjoying the beautiful area in which the trout occur.
The California Department of Fish and Games Committee on Threatened Trout has been active in working to protect and enhance the survival of the species. Attempts to widely stock the western states have been made but many populations do not last long. The population of golden trout in the South Fork Kern River was reduced by the presence of brown trout. Golden trout are now more abundant, however, than they have been in the past.
Perception Channels: tactile ; chemical
Originally, aguabonita trout were thought to be related to the Colorado River cutthroat trout, but were later recognized as a close relative of the rainbow trout. Another common name that has been used is the Volcano Creek golden trout, which refers to the place in which it was first recognized. A subspecies of golden trout that was given full species status in the early 1900s is Little Kern golden trout, Oncorhynchus aguabonita whitei. The record for the largest golden trout is 11 pounds, caught in Wyoming.
Golden trout occupy only high altitude fresh water lakes and rivers, usually in scenic mountain areas that are highly inaccessible and can only be reached by horseback riding or backpacking. These altitudes can range anywhere from 9000-12000 feet. The water in which the fish dwell is usually of very low temperatures and is of great beauty, hence, the name, aguabonita. The waters contain little weed growth.
Aquatic Biomes: lakes and ponds; rivers and streams
Golden trout are small sized members of the trout family with an overall golden color and orangish-red stripes along the side. The rear portion of the body right before the tail is often speckled with dark spots, and so is the dorsal fin. Small scales are also a distinguishing characteristic.
Range mass: 0.02 to 5 kg.
Other Physical Features: bilateral symmetry
The female golden trout's egg development starts early in their short growing season. The egg is almost completely ripe when lowering temperatures arrest development at the onset of winter. The fish are then ready to spawn the following spring. Provoked by the melting snow and thawing streams, the spawning routine, which starts anytime between March through July, begins its process, depending on weather conditions and elevation. Reproduction is sexual with external fertilization. The female lays her eggs in specific areas, and the males then come and fertilize them. The development of the egg, hatching, and early growth stages are virtually the same as in the other spring spawners.

Die Goldforelle (Oncorhynchus aguabonita) ist eine Art der Lachsfische (Salmonidae). Sie wurde zunächst als Unterart der Regenbogenforelle beschrieben, wird inzwischen aber größtenteils als eigenständige Art anerkannt. Das natürliche Verbreitungsgebiet liegt in Nordamerika.
Die Goldforelle kann bis zu 71 cm groß und fast fünf Kilogramm schwer werden (dies ist der bisherige Weltrekord von 1948[1]). Große Exemplare von über 30 Zentimeter Länge findet man vor allem, wenn sie in Seen oder Teichen ausgesetzt und gemästet werden. In der Regel erreicht diese Forelle aber höchstens 30 Zentimeter Länge. Ab 15 Zentimeter Länge sind die Fische erwachsen und geschlechtsreif. Die Körperform ist torpedoartig, seitlich leicht zusammengedrückt. Am Rücken ist die Goldforelle olivgrün, auf den Seiten und am Bauch gelbgold gefärbt, mit roten horizontalen Bändern entlang der Seitenlinie und mit etwa zehn dunklen, breiten, senkrechten, leicht ovalen Balken, die an die Jugendfärbung anderer Forellenarten erinnern. Rücken-, Brust- und Afterflossen besitzen weiße Ränder. Die Maxillare reicht bis leicht hinter das Auge, der Kopf ist verhältnismäßig lang, am Ende stumpf und etwa 3,75-mal in der Körperlänge enthalten. Die Schuppen (160 bis 180 in der Längsreihe, mit ca. 123 Poren in der Seitenlinie) sind sehr klein, rund und nicht dachziegelartig. Flossenformel: D 12; A 10[2].
Beschrieben[3] wurde die Art aus Kalifornien aus dem South Fork Kern River und dem nach ihr benannten Golden Trout Creek. Die Forelle aus dem Main River und Little Kern River[4] gilt verschiedentlich sogar als Unterart Oncorhynchus aguabonita gilberti (s. FishBase). Allerdings sind sich die Taxonomen ihrer Zuordnung nicht ganz einig, da sie gelegentlich auch als Unterart der Regenbogenforelle gilt.
Der Artname ist aus den spanischen Wörtern agua für Wasser und bonita für hübsch zusammengesetzt und bezieht sich auf den Namen eines Wasserfalls bei ihrem natürlichen Vorkommen.[5] Es gibt einen Unterschied zwischen der Goldforelle und der Goldenen Regenbogenforelle, die auch als Palominoforelle bekannt ist und eine Farbvariante der Regenbogenforelle darstellt.
Die Goldforelle wird derzeit nicht auf der Liste bedrohter Tierarten geführt, allerdings bewirkten Jahre der Überfischung, fischereiliches Missmanagement und Konflikte mit eingesetzten Fremdarten, dass diese Art beinahe als bedroht eingestuft wurde. Eingesetzte Bachsaiblinge machten ihr die Nahrung streitig, Bachforellen betätigten sich als Räuber und eingesetzte Regenbogenforellen hybridisierten mit ihr, wodurch der natürliche Genpool durch Introgression beschädigt wurde. Jahrzehntelang schrumpften die Bestände deshalb stetig. Schließlich schloss das California Department of Fish and Game im September 2004 einen Vertrag mit Bundesbehörden, um an Renaturierungsmaßnahmen zu arbeiten[6]. Naturschützer beabsichtigen auch, die Goldforelle in anderen Gewässern, wie etwa den Lake Mohave in Nevada und Arizona auszusetzen.

Ang ginintuang trutsa ay mayroong ginintuang biyas (apad o tagiliran) na may mga pahang pula at pahalang sa kahabaan ng mga guhit na pagilid sa bawat isang gilid at tinatayang 10 madirilim, patayo, at tabas-itlog na mga marka (tinatawag na mga "markang parr") sa bawat gilid. Ang mga palikpik sa palaypay ng likod, sa gilid, at sa puwitan ay may mapuputing mga pangunahing mga talim o bingit. Sa katutubo nilang mga tirahan, ang mga adulto ay humahangga magmula 6–12 pulgada (15–30 cm) ang haba. Ang mga isdang mahigit sa 10 pulgada (25 cm) ay itinuturing na malaki. Ang ginintuang trutsa na inilipat sa mga lawa ay naitalang nagkaroon ng umaabot sa 11 lb (5 kg) ang timbang. Ang rekord na pangmundo na ginintuang trutsa ay nahuli ni Charles S. Reed, noong Agosto 5, 1948, mula sa Lawang Cook sa Wind River Range, na may 28 pulgada (70 cm) ang haba at tumitimbang ng 11.25 lb (5.1 kg).[3] Ang tamang temperatura ng tubig para sa isdang ito ay 58–62 °F (14–17 °C).

The California golden trout (Oncorhynchus aguabonita or Oncorhynchus mykiss aguabonita), is a species of trout native to California. The golden trout is normally found in the Golden Trout Creek (tributary to the Kern River), Volcano Creek (tributary to Golden Trout Creek), and the South Fork Kern River. The Golden trout is the official freshwater state fish of California since 1947.[2]
The California golden trout is closely related to two rainbow trout subspecies. The Little Kern golden trout (O. m. whitei), found in the Little Kern River basin, and the Kern River rainbow trout (O. m. gilberti), found in the Kern River system. Together, these three trout form what is sometimes referred to as the "golden trout complex".[3]
Originally the golden trout was described as a subspecies of the salmon species, with a name Salmo mykiss agua-bonita,[4] and it is still often considered a subspecies (now called Oncorhynchus mykiss aguabonita) along with several other rainbow trout subspecies commonly known as redband trout.
FishBase and the Catalog of Fishes however now (2014) list O. aguabonita as an independent species rather than as subspecies of O. mykiss.[4][5] Likewise, while ITIS lists O. m. whitei and O. m. gilberti as subspecies of O. mykiss,[6] O. aguabonita instead is listed as a full species.[1][7]
The golden trout has golden flanks with red, horizontal bands along the lateral lines on each side and about 10 dark, vertical, oval marks (called "parr marks") on each side. Dorsal, lateral and anal fins have white leading edges. In their native habitat, adults range from 6 to 12 inches (15 to 30 cm) long. Fish over 12 inches (30 cm) are considered large. Golden trout that have been transplanted to lakes have been recorded up to 11 pounds (5.0 kg).
The golden trout should be distinguished from the similarly named golden rainbow trout, also known as the palomino trout. The golden rainbow is a color variant of the rainbow trout.[8]
The golden trout is commonly found at elevations from 6,890 feet (2,100 m) to 10,000 feet (3,000 m) above sea level, and is native to California's southern Sierra Nevada mountains. Outside of its native range in California, Golden trout are more often found in cirques and creeks in wilderness areas around 10,500–12,000"+, often beyond 12,500"+ passes that are not passable without crampons, ice axes, and ropes until after the Fourth of July.[9] Their preferred water temperature is 58 to 62 °F (14 to 17 °C) but they can tolerate temperatures in degraded streams on the Kern Plateau as high as 70 °F (21 °C) so long as those waters cool during the night.[9] The only other species of fish indigenous to the native range of California golden trout is the Sacramento sucker (Catostomus occidentalis occidentalis).[10]
The Wyoming Game & Fish Department state record golden trout measured 28 in (71 cm) and weighed 11.25 lb (5.10 kg), caught in Cooks Lake, Wyoming in 1948.[11] The IGFA "All-Tackle Length Record" for O. m. aguabonita measured 21 in (53 cm) caught in Golden Lake, Wyoming in 2012.[12]
O. m. aguabonita is native to the southern Sierra Nevada, including the upper reach and tributaries of the South Fork of the Kern River, and Golden Trout Creek and its tributaries.[13] It has been introduced in hundreds of lakes and streams outside the native range, though most of these populations did not last or hybridized with cutthroat trout and other subspecies of rainbow trout.[13]
In 1892, the California golden trout was originally described by David Starr Jordan, the first President of Stanford University, as Salmo mykiss agua-bonita. The fish was named after the Agua Bonita Waterfall where the first specimens were collected, at the mouth of Volcano Creek, at the creek's confluence with the Kern River.[14] A century later they were listed as Oncorhynchus mykiss aguabonita in Behnke's Native trout of western North America.[15]
In 1904, Stewart Edward White communicated to his friend President Theodore Roosevelt, that overfishing could lead to extinction of the golden trout. In White's novel The Mountains, he wrote about the threatened golden trout on California's Kern Plateau. Roosevelt shared White's concern and, through U.S. Fish Commissioner George M. Bowers, dispatched biologist Barton Warren Evermann of the U.S. Bureau of Fisheries to study the situation. In 1906 Evermann published The Golden Trout of the Southern High Sierras.[16] Based on morphology, Evermann accurately described four forms of this native fish: Salmo roosevelti from Golden Trout (Volcano) Creek, Salmo aguabonita from nearby South Fork of the Kern River, Salmo whitei (named in recognition of Stewart Edward White) from the Little Kern River, and Salmo gilberti, the Kern River rainbow.[10]
Genetic studies have since clarified three groups of trout native to the Kern River: California golden trout (O. m. aguabonita) native to the South Fork Kern River and Golden Trout Creek (tributary to the Kern River mainstem but the historic course of the South Fork Kern River and now only separated from it by a lava flow and ridge of sediment), Little Kern River golden trout (O. m. whitei), and Kern River rainbow trout (O. m. gilberti).[17]
Years of overexploitation, mismanagement and competition with exotic species have brought golden trout to the brink of being designated as "threatened". Introduced brook trout (Salvelinus fontinalis) outcompete them for food, introduced brown trout (Salmo trutta) prey on them and introduced rainbow trout (O. mykiss) hybridize with them, damaging the native gene pool through introgression. Populations have been in steady decline for decades.
In 1978, the Golden Trout Wilderness was established within Inyo National Forest and Sequoia National Forest, protecting the upper watersheds of the Kern River and South Fork Kern River.
In September 2004, the California Department of Fish and Game signed an agreement with federal agencies to work on restoring back-country habitat, heavily damaged by overgrazing from cattle and sheep, as part of a comprehensive conservation strategy.[9]
The US Endangered Species Act (USESA) designated the subspecies O. m. whitei as LT, or Listed Threatened, since 1978, under the name Oncorhynchus aguabonita whitei.[18]
NatureServe has designated the following NatureServe Conservation Status for the three subspecies:
The American Fisheries Society has designated all three subspecies as Threatened since August 2008.[13][18][19]
For sportfishing, the golden trout underwent many twentieth century translocations into multiple Western states and established populations survive in California, Idaho, Montana, Utah, Washington, Colorado, and Wyoming. Populations in the high-elevation lakes in the Ruby Mountains, Nevada, have died out.[20] The current status in other states where the California golden trout were planted (Arizona, New Mexico and Oregon) lacks documentation.
A self-sustaining introduced population also exists in the Rocky Mountains of Alberta, Canada; the province's golden trout population is managed by translocating fish between lakes to balance populations, but no new fish from other populations are introduced.[21]
When Colonel Chuck Yeager introduced one of his commanding officers, General Irving "Twig" Branch, to the Sierra Nevada populations of golden trout, Branch ordered Yeager and Bud Anderson to introduce the species to the mountain streams of New Mexico.[22] However, the New Mexico populations have also died out.[20]
In his second autobiography, Press On, Yeager details his annual fishing trips to catch golden trout which he extols as one of the best game fish and best eating fish to be found.

Oncorhynchus aguabonita
La Truite dorée (Oncorhynchus aguabonita, syn. Oncorhynchus mykiss aguabonita) est une espèce de poissons salmoniformes, originaire d'Amérique du Nord.
De goudforel (Oncorhynchus mykiss aguabonita, synoniem: Salmo aqua-bonita) is een ondersoort van de regenboogforel, die voorkomt in bergbeken van de Sierra Nevada. Het gewicht van een volwassen vis is ruim 5 kilogram.
De goudforel heeft een olijf-groene rug en heldere rood overgaand naar goudkleurige zijden en buik. In de paaitijd zijn de kleuren helderder. Het is de kleurigste van de forellen.
Het dier meet maximaal 70 cm en eet schaaldieren en insecten. De paaitijd valt in oktober en november. De biotoop van de goudforel was oorspronkelijk beperkt tot meren en stromen die op hoogten van meer dan 1500 m voorkwamen. Ze zijn later ook in lager gelegen meren geïntroduceerd, maar deze vissen lijken dan bleker te worden.

Cá hồi vàng hay cá hồi hoàng kim hay còn gọi là cá hồi vàng California (Danh pháp khoa học: Oncorhynchus mykiss aguabonita), là một phân loài của loài cá hồi vân có nguồn gốc từ California. Các con cá hồi vàng có nguồn gốc từ vùng Golden Trout Creek (nhánh sông Kern), Volcano Creek (nhánh Golden Trout Creek), và sông South Fork Kern. Các cá hồi vàng California có liên quan chặt chẽ với hai phân loài cá hồi cầu vồng khác tạo thành nhóm phức hợp cá hồi.
Phân loài Oncorhynchus mykiss whitei, được tìm thấy ở lưu vực nhỏ sông Kern, và cá hồi vân sông Kern (Oncorhynchus mykiss gilberti), được tìm thấy trong hệ thống sông Kern. Ban đầu cá hồi vàng đã được mô tả như là một phân loài của cá hồi cầu vồng, với một tên Salmo mykiss agua-bonita, và nó vẫn thường được coi là một phân loài (bây giờ gọi là Oncorhynchus mykiss aguabonita) cùng với một số phân loài cá hồi cầu vồng khác.
Cá hồi vàng (O. m. aguabonita) có nguồn gốc ở miền nam Sierra Nevada, bao gồm cả thượng và các nhánh của South Fork của sông Kern, và Golden Trout Creek và các nhánh của nó. Nó đã được du nhập trong hàng trăm hồ và suối bên ngoài phạm vi bản địa, mặc dù hầu hết các quần thể không kéo hoặc lai với cá hồi và phân loài khác của cá hồi vân, dữ liệu phân phối có thể không đầy đủ hoặc không chính xác bao gồm các tỉnh của Canada Alberta, và các tiểu bang Hoa Kỳ như Arizona, California, Colorado, Idaho, Montana, New Mexico, Nevada, Oregon, Utah, Washington và Wyoming.
Các cá hồi vàng có hai cánh vàng với màu đỏ, băng ngang dọc theo dòng bên mỗi bên và khoảng 10 sọc tối, dọc, dấu hình bầu dục trên mỗi bên. Vây lưng, vây bên và hậu môn có mép trắng. Trong môi trường sống tự nhiên của chúng, cá thể trưởng thành có chiều dài khoảng 6-12 inch (15-30 cm). Cá trên 12 inch (30 cm) được coi là cá lớn. Cá hồi vàng đã được cấy vào hồ đã được ghi nhận lên đến 11 pound (5,0 kg). Các cá hồi vàng nên được phân biệt với các tên tương tự như cá hồi vân vàng, còn được gọi là cá hồi Palomino. Các cầu vồng vàng là một biến thể màu sắc của cá hồi cầu vồng.
Các con cá hồi vàng thường được tìm thấy ở độ cao từ 6.890 feet (2.100 m) đến 10.000 feet (3.000 m) trên mực nước biển, và là nguồn gốc duy nhất phía nam dãy núi Sierra Nevada của California. Bên ngoài phạm vi nguồn gốc của nó ở California, chúng thường được tìm thấy trong cirques và lạch tại khu vực hoang dã khoảng 10.500-12.000"+, thường vượt quá 12.500 cho đến sau Thứ tư của tháng bảy, nhiệt độ nước ưa thích của chúng là 58-62 °F (14-17 °C), nhưng chúng có thể chịu được nhiệt độ trong dòng suy thoái trên Kern cao nguyên cao như 70 °F (21 °C), miễn là những nước mát trong đêm.
