Rainbow Trout

Oncorhynchus mykiss

Sea Life Introduced IUCN: Not Evaluated

About

Variable in colour - fish in lakes are mostly greenish or steely-blue above, with a silvery-white belly, usually a prominent rosy-pink stripe along the sides and small black spots on the body and fins. Individual fish in lakes may be silvery without a pink stripe. Juveniles often have dark blotches along the sides that disappear with growth.
Native to western coastal drainages of North America, Rainbow trout were first introduced to Australia from New Zealand in 1894. Although an extremely popular freshwater gamefish, the introduction of Rainbow Trout into our freshwaters has severely impacted native fish populations.
