Western Australian Salmon
(Arripis truttaceus)

Western Australian Salmon (Arripis truttaceus) (hereafter referred to as ‘Salmon’) comprises a migratory biological stock that extends from southern Western Australia to the east coast of Tasmania, with each State jurisdiction harvesting different life-history stages. Western Australian Salmon intermix with Eastern Australian Salmon (A. trutta) in eastern Victorian waters and around Tasmania. The Western Australian fishery typically targets adult fish that aggregate around the south-western coastline, whereas the South Australian, Victorian and Tasmanian fisheries predominantly harvest juveniles and sub-adults in coastal waters as they migrate along the southern coast of Australia.

Salmon form large spawning schools in coastal waters between Cape Leeuwin and Busselton, Western Australia, during late autumn and early winter when the eastward flow of the Leeuwin Current is strongest. Developing larvae settle along the entire southern coastline of Australia, with the main nursery grounds located along the south-eastern coast. Juveniles remain in coastal nursery areas for approximately three years where they feed on epibenthic crustaceans and small fish associated with seagrass beds. As they mature and begin to migrate back to the spawning grounds, their diet shifts to small pelagic fish, predominantly Australian Sardines and Australian anchovies. Salmon attain a maximum age of ~12 years and can reach a maximum size of 850 mm FL.
