Oncorhynchus mykiss NatureServe Explorer Species Reports — NatureServe Explorer is a source for authoritative conservation information on more than 50,000 plants, animals and ecological communtities of the U.S and Canada. NatureServe Explorer provides in-depth information on rare and endangered species, but includes common plants and animals too. NatureServe Explorer is a product of NatureServe in collaboration with the Natural Heritage Network.

ITIS Reports — Oncorhynchus mykiss ITIS (the Integrated Taxonomic Information System) is a source for authoritative taxonomic information on plants, animals, fungi, and microbes of North America and the world. Class: Actinopterygii. Summary of Invasiveness. Oncorhynchus mykiss is a competitive trout species which can displace native trout species when introduced into new environments; the fisheries management literature is replete with papers that document.  For many years the O. mykiss native to North America ( Salmo gairdneri) was thought to be a different species from the trout native to Kamchatka ( Salmo mykiss ), but they are now considered to be the same species.

FWS Digital Media Library — The U.S. Fish and Wildlife Service’s National Digital Library is a searchable collection of selected images, historical artifacts, audio clips, publications, and video. Prior to 1989, O. mykiss were classified as part of the trout genus, having the scientific name Salmo gairdneri, but they were reclassified as Oncorhynchus mykiss in 1989, and are thus more closely related to Pacific salmon than to other trout species ( Smith and Stearley, 1989 ). Oncorhynchus mykiss has a streamlined body with adipose fin. They are deep-bodied and sideways compressed. Average length of Oncorhynchus mykiss is 30-45 cm and the anadromous form steelhead 50-75 cm. Extremely large sea-run individuals can be more than 120 cm in length and above 25 kg in mass. The general body shape is typical for a trout, with a moderately large head.
