AnAge entry for Oncorhynchus mykiss

Classification (HAGRID: 04094)

Taxonomy: Kingdom: Animalia
    Phylum: Chordata
        Class: Teleostei
            Order: Salmoniformes
                Family: Salmonidae
                    Genus: Oncorhynchus
Species: Oncorhynchus mykiss
Common name: Steelhead
Synonyms: Salmo mykiss, Onchorynchus mykiss, Salmo gibbsii, Oncorhynchus mykiss gibbsi

Maximum longevity: 11 years (wild)
Source: ref. 454
Sample size: Medium
Data quality: Acceptable
Observations: Some evidence suggests that the steelhead has very slow ageing if it can return to the ocean after spawning [0014]. Otherwise it will age and die just like it occurs with the salmon. Telomerase activity has been detected in these animals [0017]. High mortality in streams in older fishes has also been reported [0442].
