As trout are predatory fish, lure fishing (which use replica baits called lures to imitate live prey) is the predominant form of sport fishing involving trout, although traditional bait fishing techniques using floats and/or sinkers (particularly with moving live baits such as baitfish, crayfish or aquatic insects) are also successful ...
The rainbow trout (Oncorhynchus mykiss) is a species of trout native to cold-water tributaries of the Pacific Ocean in North America and Asia. The steelhead (sometimes called steelhead trout) is an anadromous (sea-run) form of the coastal rainbow trout (O. m. irideus) or Columbia River redband trout (O. m. gairdneri) that usually returns to freshwater to spawn after living two to three years ...
The Eagle Lake trout has a pink horizontal band, white rimmed fins, and irregular spots across its body which become less prolific towards the belly. Large square-shaped tales, large eyes, and a large body give the fish a predatory advantage in the lake.
However, once they return to freshwater, they quickly take on the normal coloration of resident brown trout in preparation for spawning. Sea trout kelts (post spawn) return to their silvery stage as they migrate back to saltwater. [9] Adult brown trout are between 35 and 60 cm (14 and 24 in) long, and can weigh from 0.5 to 2.4 kg (1.1 to 5.3 lb).
Steelhead in 1924 illustration using the original taxonomic name, Salmo gairdneri The freshwater form of the steelhead is the rainbow trout (Oncorhynchus mykiss).The difference between these forms of the species is that steelhead migrate to the ocean and return to freshwater tributaries to spawn, whereas non-anadromous rainbow trout do not leave freshwater.
Some coastal rainbow trout (Oncorhynchus mykiss irideus) and Columbia River redband trout (O. m. gairdneri) populations also display reddish or pink throat markings. [ 23 ] At maturity, different populations and subspecies of cutthroat trout can range from 6 to 40 inches (15 to 102 cm) in length, depending on habitat and food availability.
The pectoral, pelvic, anal, and the lower aspect of caudal fins are trimmed in snow white or cream leading edges. Many members of this genus are popular sport fish, and a few, such as lake trout ( S. namaycush ) and arctic char ( S. alpinus ) are objects of commercial fisheries and/or aquaculture .
The brown trout (Salmo trutta) is a species of salmonid ray-finned fish and the most widely distributed species of the genus Salmo, endemic to most of Europe, West Asia and parts of North Africa, and has been widely introduced globally as a game fish, even becoming one of the world's worst invasive species outside of its native range.
