Fishes Of Yellowstone National Park
The fish of Yellowstone National Park, in Idaho, Montana and Wyoming (U.S.), include 13 native fish species and six introduced or non-native species. Angling for trout has been a pastime in the park since its creation and trout species dominate the fish inhabiting the park. When Yellowstone National Park was created in 1872, 40% of the park's waters were barren of fish, including most alpine lakes and rivers above major waterfalls. Only 17 of 150 lakes held fish. In 1889 the U.S. Bureau of Fisheries began a 60-year program of stocking and hatchery operations that significantly altered the ranges of native and non-native species within the park. By 1955, all stocking and hatchery operations in the park had been stopped. Several introduced species never established viable populations, and at least one introduced species was successfully eradicated from the park. Native species The following fish are native to the park, although their original ranges may have been severely reduc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longnose Sucker
The longnose sucker (''Catostomus catostomus'') is a species of cypriniform freshwater fish in the family Catostomidae. It is native to North America from the northern United States to the top of the continent. It is also found in Russia in rivers of eastern Siberia, and thus one of only two species of sucker native to Asia (the other is the Chinese '' Myxocyprinus asiaticus''). Description The body of the longnose sucker is long and round with dark olive or grey sides and top and a light underside. They are up to in total length and weigh up to . Longnose suckers are easily confused with white suckers (''Catostomus commersoni''), which appear very similar. However, longnose suckers can be distinguished by their comparatively finer scales. Distribution and ecology The longnose sucker inhabits cold, clear waters, including lakes, pools, rivers and streams, and occasionally also brackish waters. In North America, it ranges north from the Columbia, Delaware, Missouri and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continental Divide
A continental divide is a drainage divide on a continent such that the drainage basin on one side of the divide feeds into one ocean or sea, and the basin on the other side either feeds into a different ocean or sea, or else is endorheic, not connected to the open sea. Every continent on earth except Antarctica (which has no known significant, definable free-flowing surface rivers) has at least one continental drainage divide; islands, even small ones like Killiniq Island on the Labrador Sea in Canada, may also host part of a continental divide or have their own island-spanning divide. The endpoints of a continental divide may be coastlines of gulfs, seas or oceans, the boundary of an endorheic basin, or another continental divide. One case, the Great Basin Divide, is a closed loop around an endoreic basin. The endpoints where a continental divide meets the coast are not always definite since the exact border between adjacent bodies of water is usually not clearly defined. The In ...

Speckled Dace
The speckled dace (''Rhinichthys osculus''), also known as the spotted dace and the carpita pinta, is a member of the minnow family. It is found in temperate freshwater in North America, from Sonora, Mexico to British Columbia, Canada. Canada is the northern limit of the speckled dace's distribution, and there it is found only in isolated parts of the Kettle and Granby Rivers. It is possible that, along with the Salish sucker (''Catostomus'' sp.), the speckled dace was one of the first fish to recolonize the rivers of British Columbia following the Ice Age. It is believed that spawning in Canada occurs once a year during the summer in fish older than two years. During breeding, many males often accompany a single female who broadcasts adhesive eggs over the gravelly stream bed. Each female produces between 200 and 500 eggs. Speckled dace are omnivorous, feeding upon filamentous algae and other plant material, bottom-dwelling aquatic insects and zooplankton. The speckled dac ...

Yellowstone Lake
Yellowstone Lake is the largest body of water in Yellowstone National Park. The lake is above sea level and covers with of shoreline. While the average depth of the lake is , its greatest depth is at least . Yellowstone Lake is the largest freshwater lake above in North America. In winter, ice nearly thick covers much of the lake except where shallow water covers hot springs. The lake freezes over by early December and can remain frozen until late May or early June. History The forest and valleys surrounding Yellowstone Lake had been populated with Native Americans since pre-historic times. Archeologists have found evidence of human presence in the park long before 1872. They found that Native Americans hunted bison and bighorn sheep, fished for Cutthroat Fish, and gathered bitterroot and camas bulbs for at least 11,000 years. Also 26 tribes claim cultural association with Yellowstone today. The first human of European descent to see the lake was trapper John Colter in the ...

Longnose Dace
The longnose dace (''Rhinichthys cataractae'') is a freshwater minnow native to North America. ''Rhinicthys'' means snout fish (reference to the long snout) and ''cataractae'' means of the cataract (first taken from Niagara Falls). Longnose dace are small, typically less than 100 mm and characterized by their fleshy snout that protrudes past the mouth. They are well adapted for living on the bottom of fast-flowing streams among stones. Longnose dace eat algae and aquatic insects and are important forage minnows for larger predatory fish. Description Longnose dace can be mistaken for suckers because of their subterminal "sucker-like" mouth. However, longnose dace (like all members of the family cyprinidae) lack small fleshy projections, called papillae, on their mouths. Juveniles have a black lateral line that extends from the beginning of the eye to the caudal fin that fades as the fish matures. The lateral line in juveniles is not present in all populations. In adults, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snake River
The Snake River is a major river of the greater Pacific Northwest region in the United States. At long, it is the largest tributary of the Columbia River, in turn, the largest North American river that empties into the Pacific Ocean. The Snake River rises in western Wyoming, then flows through the Snake River Plain of southern Idaho, the rugged Hells Canyon on the Oregon–Idaho border and the rolling Palouse Hills of Washington, emptying into the Columbia River at the Tri-Cities in the Columbia Basin of Eastern Washington. The Snake River drainage basin encompasses parts of six U.S. states (Idaho, Washington, Oregon, Utah, Nevada, and Wyoming) and is known for its varied geologic history. The Snake River Plain was created by a volcanic hotspot which now lies underneath the Snake River headwaters in Yellowstone National Park. Gigantic glacial-retreat flooding episodes during the previous Ice Age carved out canyons, cliffs, and waterfalls along the middle and lower Snake Riv ...

Heart River (Wyoming)
The Heart River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed May 4, 2011 river in the U.S. state of Wyoming, tributary to the Snake River. Its entire course is contained inside Yellowstone National Park. The river rises on the Continental Divide, in the Rocky Mountains, a few miles southeast of Yellowstone Lake. Its headwater streams flow into Heart Lake, from whose southeastern end the main Heart River issues, receiving two tributary streams from the northeast and flowing southwest into a short but steep gorge. It then continues generally south for roughly before emptying into the Snake near the boundary with the Teton National Forest.

Heart Lake (Wyoming)
Heart Lake el. is a large backcountry lake, nestled at the base of Mount Sheridan in Yellowstone National Park. Heart Lake is in the Snake River drainage and is drained by the Heart River. History Heart Lake was apparently named sometime prior to 1871 for a local 1840s hunter, Hart Hunney, a fact that was later verified by Hiram Chittenden. In 1871, Captain John W. Barlow thought the name was ''Heart Lake'' because of it shape and the name became its official name. During the Arnold Hague Geologic Surveys, Chittenden petitioned Hague to change the name back to ''Hart'', but Hague thought that ''Heart Lake'' was named because of the lake's shape and refused to change it. In 1870 a member of the Washburn-Langford-Doane Expedition, the solitary explorer Truman C. Everts, who had become separated from the rest of his party, probably camped on the shores of Heart Lake and named it Bessie Lake after his daughter.

Utah Sucker
The Utah sucker (''Catostomus ardens'') is a species of freshwater fish in the family (biology), family Catostomidae found in the upper Snake River and the Lake Bonneville areas of western North America where it lives in a wide range of habitats. It is a large sucker growing up to long. It is generally blackish above, vaguely streaked and blotched, with a white belly. A narrow rosy lateral band extends backwards from the head. The mouth has thick lips and is on the underside of the head. Some populations are in decline because of anthropogenic factors but overall this fish is not threatened. Description This is a large fish that can grow up to 25.5" (65 cm) in length. Relatively elongate for a Catostomidae, sucker, the Dorsum (anatomy), back area between the head and dorsal fin is somewhat elevated. The mouth is entirely under the snout, with thick lips, of which the upper lip has eight rows of coarse wiktionary:Papilla, papillae, the second and third rows from the inside be ...

Mountain Sucker
The mountain sucker (''Catostomus platyrhynchus'') is a sucker found throughout western North America, on both sides of the Rocky Mountains, including the upper Missouri River, Columbia River, Sacramento River, and Colorado River. It is not limited to higher altitudes but is known from locations as high as . It is a slender, streamlined fish typically under in length. It is generally olive green or brown above, with pale underparts, and breeding males have a lateral red-orange band and fins suffused with the same color. It is mainly herbivorous, feeding on algae and diatoms. Breeding takes place in late spring and early summer in gravelly riffles in small streams. Description This is a slender and streamlined sucker, generally olive green to brown above and on the sides, and white to yellowish underneath. There may be a pattern of darker blotches along the sides. Adult males will also have a dark red-orange band over a dark green band on each side, and during breeding season t ...

Gardner River
The Gardner River (also known as the Gardiner River) is a tributary of the Yellowstone River, approximately long, in northwestern Wyoming and south central Montana in the United States. The entire river is located within Yellowstone National Park. It rises on the slope of Joseph Peak, Gallatin Range in the northwestern part of the park, and winds southeast through Gardner's Hole, a broad subalpine basin which is a popular trout fishing location. The Gardner falls within the Native Trout Conservation Area and anglers are allowed to take an unlimited number of brown and rainbow trout. Mountain whitefish and Yellowstone cutthroat trout must be released. Angling on the Gardner is governed by Yellowstone National Park fishing regulations. After merging with Panther Creek, Indian Creek and Obsidian Creek, it then turns north and flows through a steep canyon where it cuts through a basaltic flow from approximately 500,000 years ago known as Sheepeater Cliffs.
