I love Cutties

 Hi All

Borrowed from Wikipedia

The cutthroat trout (Oncorhynchus clarkii) is a species of freshwater fish in the salmon family oforder Salmoniformes. It is one of the many fish species colloquially known as trout. All subspecies of cutthroat trout are sought after gamefish, especially among anglers who enjoy fly fishing.

Range and habitat

Cutthroat trout are native to western North America. The cutthroat species has evolved throughgeographic isolation into many subspecies, each native to a different major drainage basin. Native cutthroat species are found along the Pacific Northwest coast, in the Cascade Range, the Great Basin, and throughout the Rocky Mountains. Some coastal populations are anadromous, living primarily in the Pacific Ocean as adults and returning to fresh water from fall through early spring to feed on insects and spawn. Most populations, however, stay in freshwater throughout their lives and are known as non-migratory, stream-resident or riverine populations. Anadromous fish may reach weights of 20 pounds (9 kg), but those fish which remain permanently in freshwater may only reach a weight of 2 pounds (1 kg). At least three subspecies are confined to isolated basins in the Great Basin and can tolerate saline or alkaline water.

[edit]Description

Throughout their native and introduced range, cutthroat trout vary widely in size, coloration, and habitat selection. Though their coloration can range from golden to gray to green on the back, depending on subspecies strain and habitat, all populations universally feature distinctive red, pink, or orange marks on the underside of the lower jaw or below the gill plates; usually the easiest diagnostic of the species for the casual observer. These markings are responsible for the formation of the typical name "cutthroat". At maturity, different populations and subspecies of cutthroat can range from 6–40 inches (15–100 cm) in length, depending on habitat and food availability, making size an ineffective indicator as to species identity. Cutthroat are typically prized as a sportfish, particularly by fly anglers, as their propensity to inhabit remote waters and dimunitive streams appeals to the sense of adventure present in many outdoor enthusiasts. In addition, their tendency to exhibit significant activity and resistance to anglers in conjunction with this species' affinity for terrestrial or mature insects serves to increase popularity of the cutthroat as a angler's quarry. Finally, the cutthroat participates in a unique predator-prey relationship with the bull trout that is key to ecosystem integrity across much of its natural range.

Cutthroat will readily interbreed with the closely related rainbow trout, producing fertile hybrids commonly called "cutbow". As this species generally bears similar coloration and overall appearance to the cutthroat, retaining the characteristic orange-red slash, these hybrids often pose a taxonomical difficulty. In addition, Cutthroat will also hybridize with the O. gilae subspecies, the Gila trout and Apache trout in regions where their ranges overlap.  

Trivia

The cutthroat trout is the state fish of Idaho and Wyoming, while particular subspecies of cutthroat are the state fish of Colorado, Montana, Nevada, New Mexico, and Utah.

I learn something every day...Guess I am not as old as I feel.  

Very Nice dave was sweet little viedo and nice looking fish  very pretty

Thanks Guy's . You all should google the Cut  in the spawn  I am looking for a picture to post. They are bright orange-red amazing color. Just plain beautiful.  Thanks for the explanation Stephen .
