Arripis truttaceus
Western australian salmon
Distribution
Temperate Australasia
Description
Fish spawn along the southern Western Australia coast during autumn, after which most of the juvenile fish population moves eastwards with the prevailing current during the first year. The Victorian and Tasmanian population grows more slowly than the western population and migrates westward for spawning after four to six years, at about 500 mm in length.

Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Infrequent (5.9% of sites)
Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed
Abundance: Large aggregations (144 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
