Pysht River
The Pysht River ( ) is a stream in the U.S. state of Washington. It originates near Ellis Mountain in the northern Olympic Mountains on the Olympic Peninsula and flows generally north, emptying into the Strait of Juan de Fuca. The Pysht and nearby Hoko River are the two largest streams flowing into the southwestern portion of the Strait of Juan de Fuca. The watershed of the Pysht River drains a region of industrial forest lands; 98% of the watershed is zoned commercial forestry and the remainder rural. Nearly all of the forests have been logged at least once and most trees are less than thirty years old. The upper portions of the watershed, which feature steep gradients, are owned by the United States Forest Service. The lower reaches, with low gradients, are largely owned by two industrial forest owners. The name of the Pysht River comes from the Clallam (Salishan) ''pəšc't'', perhaps meaning "against the wind or current". Course The Pysht River originates near Ellis Mountain ...

Tannin Stained Water
A blackwater river is a type of river with a slow-moving channel flowing through forested swamps or wetlands. As vegetation decays, tannins leach into the water, making a transparent, acidic water that is darkly stained, resembling black tea. Most major blackwater rivers are in the Amazon Basin and the Southern United States. The term is used in fluvial studies, geology, geography, ecology, and biology. Not all dark rivers are blackwater in that technical sense. Some rivers in temperate regions, which drain or flow through areas of dark black loam, are simply black due to the color of the soil; these rivers are ''black mud rivers''. There are also black mud estuaries. Blackwater rivers are lower in nutrients than whitewater rivers and have ionic concentrations higher than rainwater. The unique conditions lead to flora and fauna that differ from both whitewater and clearwater rivers. The classification of Amazonian rivers into black, clear, and whitewater was first proposed b ...

Starry Flounder
The starry flounder (''Platichthys stellatus''), also known as the grindstone, emery wheel and long-nosed flounder, is a common flatfish found around the margins of the North Pacific. The distinctive features of the starry flounder include the combination of black and white-to-orange bar on the dorsal fin, dorsal and anal fins, as well as the skin covered with Scale (zoology), scales modified into tiny star-shaped plates or tubercles (thus both the common name and species epithet), resulting in a rough feel. The eyed side is black to dark brown, while the lower side is white or cream-colored. Although classed as "righteye flounders," individuals may have their eyes on either the right or left side. They have been recorded at up to 91 cm and 9 kg. Starry flounders are inshore fish, ranging up estuary, estuaries well into the freshwater zone, to the first riffles, with young found as much as 120 km inland. In marine environments, they occur as deep as 375 m. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainbow Trout
The rainbow trout (''Oncorhynchus mykiss'') is a species of trout native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead (sometimes called "steelhead trout") is an anadromous (sea-run) form of the coastal rainbow trout or Columbia River redband trout that usually returns to freshwater to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead. Adult freshwater stream rainbow trout average between , while lake-dwelling and anadromous forms may reach . Coloration varies widely based on subspecies, forms, and habitat. Adult fish are distinguished by a broad reddish stripe along the lateral line, from gills to the tail, which is most vivid in breeding males. Wild-caught and hatchery-reared forms of the species have been transplanted and introduced for food or sport in at least 45 countries and every continent except ...

Coastal Cutthroat Trout
The coastal cutthroat trout (''Oncorhynchus clarkii clarkii''), also known as the sea-run cutthroat trout, blue-back trout or harvest trout, is one of the several subspecies of cutthroat trout found in Western North America. The coastal cutthroat trout occurs in four distinct forms. A semi-anadromous or sea-run form is the most well known. Freshwater forms occur in both large and small rivers and streams and lake environments. The native range of the coastal cutthroat trout extends south from the southern coastline of the Kenai Peninsula in Alaska to the Eel River in Northern California. Coastal cutthroat trout are resident in tributary streams and rivers of the Pacific basin and are rarely found more than from the ocean. Adults migrate from the ocean to spawn in fresh water. Juveniles migrate to the sea where they feed and become sexually mature before returning to fresh water to overwinter and spawn. Unlike steelhead and Pacific salmon, coastal cutthroat do not make lengthy m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chum Salmon
The chum salmon (''Oncorhynchus keta''), also known as dog salmon or keta salmon, is a species of anadromous salmonid fish from the genus '' Oncorhynchus'' (Pacific salmon) native to the coastal rivers of the North Pacific and the Beringian Arctic, and is often marketed under the trade name silverbrite salmon in North America. The English name "chum salmon" comes from the Chinook Jargon term ''tzum'', meaning "spotted" or "marked"; while ''keta'' in the scientific name comes from Russian, which in turn comes from the Evenki language of Eastern Siberia. In Japan, chum salmon is also known as the , or simply , while historically it was known in ''kun'yomi'' as up until the Meiji period. In Greater China, it is known academically as the " hook-snout salmon" ( zh, 钩吻鲑), but is more often called the ''damaha'' fish (), which is borrowed from ''dawa ịmaχa'', the Nanai name of the fish used by the Hezhe minority in northern Northeast China.

Coho Salmon
The coho salmon (''Oncorhynchus kisutch;'' Karuk: achvuun) is a species of anadromous fish in the salmon family and one of the five Pacific salmon species. Coho salmon are also known as silver salmon or "silvers". The scientific species name is based on the Russian common name ''kizhuch'' (кижуч). Description During their ocean phase, coho salmon have silver sides and dark-blue backs. During their spawning phase, their jaws and teeth become hooked. After entering fresh water, they develop bright-red sides, bluish-green heads and backs, dark bellies and dark spots on their backs. Sexually maturing fish develop a light-pink or rose shading along the belly, and the males may show a slight arching of the back. Mature adults have a pronounced red skin color with darker backs and average and , occasionally reaching up to . They also develop a large kype (hooked beak) during spawning. Mature females may be darker than males, with both showing a pronounced hook on the nose. Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinook Salmon
The Chinook salmon (''Oncorhynchus tshawytscha'') is the largest and most valuable species of Pacific salmon in North America, as well as the largest in the genus ''Oncorhynchus''. Its common name is derived from the Chinookan peoples. Other vernacular names for the species include king salmon, Quinnat salmon, Tsumen, spring salmon, chrome hog, Blackmouth, and Tyee salmon. The scientific species name is based on the Russian common name ''chavycha'' (чавыча). Chinook are anadromous fish native to the North Pacific Ocean and the river systems of western North America, ranging from California to Alaska, as well as Asian rivers ranging from northern Japan to the Palyavaam River in the Arctic northeast Siberia. They have been introduced to other parts of the world, including New Zealand, thriving in Lake Michigan Great Lakes of North America and Michigan's western rivers, and Patagonia. A large Chinook is a prized and sought-after catch for a sporting angler. The flesh of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cottus Asper
''Cottus asper'' is a species of fish in the sculpin family known by the common name prickly sculpin. It is native to the river drainages of the Pacific Slope of North America from Seward, Alaska south to the Ventura River of Southern California.

Cottus Aleuticus
The Coastrange sculpin (''Cottus aleuticus'') is a freshwater sculpin of the genus '' Cottus''. They are commonly found near the ocean in western North America, namely Canada and the United States. It is also known as the Aleutian sculpin. Taxonomy While the name ''Uranidea microstoma'' has been used since 1880, it is unclear whether or not it corresponds to the Coastrange sculpin. The species was first officially described by Charles Henry Gilbert in 1896 from specimens he collected in streams of Unalaska island the year before. ''Cottus protrusus'' was described in 1933, but it has since been found to be a synonym. Description The Coastrange sculpin can be distinguished from other species due to several unique traits. It only has one pore under its chin, no palatine teeth, and no distinct gap between the two dorsal fins. Adults can grow to be as long as 17 cm, although their average length is only 6 cm. Their maximum reported life span is 8 years. Breeding female Coa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cottus (fish)
''Cottus'' is a genus of the mainly freshwater ray-finned fishes belonging to the family Cottidae, the typical sculpins. They are often referred to as the "freshwater sculpins", as they are the principal genus of sculpins to be found in fresh water. They are native to the Palearctic and Nearctic. They are small fish, mostly less than in length, although a few species can reach twice that size. Taxonomy ''Cottus'' was first proposed as a genus by Carl Linnaeus in the 10th edition of the ''Systema Naturae'' when he described the European bullhead (''Cottus gobio'') and in 1850 this species was designated as the type species of the genus by the French ichthyologist Charles Frédéric Girard. The 5th edition of the ''Fishes of the World'' classifies this genus within the subfamily Cottinae of the family Cottidae. Other authorities have found that the Cottidae, as delimited in the 5th edition of Fishes of the World, is paraphyletic and that the monophyletic grouping is the freshwate ...
