AnAge entry for Oncorhynchus tshawytscha

Classification (HAGRID: 04096)

Taxonomy: Kingdom: Animalia
    Phylum: Chordata
        Class: Teleostei
            Order: Salmoniformes
                Family: Salmonidae
                    Genus: Oncorhynchus
Species: Oncorhynchus tshawytscha
Common name: Chinook salmon

Maximum longevity: 9 years (wild)
Source: ref. 1
Sample size: Medium
Data quality: Acceptable
Observations: As in other species of salmon, these animals normally age and die shortly after spawning. It is not considered ageing but rather sudden death. Although normally semelparous, the chinook salmon has alternative iteroparous life histories. Male jacks and parr mature early and parr can survive reproduction and mate again [0819].
