⭐ Core Definition: Pacific trout

Oncorhynchus, from Ancient Greek ὄγκος (ónkos), meaning "bend", and ῥύγχος (rhúnkhos), meaning "snout", is a genus of ray-finned fish in the subfamily Salmoninae of the family Salmonidae, native to coldwater tributaries of the North Pacific basin. The genus contains sixteen extant species, namely six species of Pacific salmon and ten species of Pacific trout, all of which are migratory (either anadromous or potamodromous) mid-level predatory fish that display natal homing and semelparity.

The name of the genus is derived from Ancient Greek ὄγκος (ónkos), meaning "bend", and ῥύγχος (rhúnkhos), meaning "snout", in reference to the hooked secondary sexual characteristic — known as the kype — that the males develop on the lower jaw tip during mating season.

Pacific trout in the context of Hucho

Hucho is a genus of large piscivorous salmonid fish known as taimens (from Finnish taimen, 'trout', through Russian: тайме́нь, romanized: taĭménʹ), and is closely related to Pacific trout and lenoks (all belonging to the same tribe in the subfamily Salmoninae). Native to the cold rivers and other freshwater habitats in Eurasia, they are threatened by overfishing and habitat loss.

The earliest fossil remains of this genus are known from the Late Oligocene to middle Miocene of the Vitim Plateau in Russia. Younger remains are also known from the Late Miocene of Ukraine and the Late Pleistocene of Germany. Fossil specimens of a Hucho-like salmonid have been recovered from the Clarkia fossil beds and other localities from the late Neogene of western North America, suggesting they may have potentially inhabited North America too.
