Scientific Name
Arripis truttacea

Common Name
Western Australian salmon

Biology
Inhabit continental shelf waters including estuaries, bays and inlets. They school in shallow, open coastal waters, and can move over reefs in depths just sufficient to cover their bodies. Juveniles are found over soft substrates in shallow and sheltered coastal waters. They are often found over seagrass beds and in mangrove-lined creeks. Larger fish move into exposed, coastal waters, such as around rocky headlands, near reefs and the surf zone. Feeds on fishes. Minimum depth reported taken from Ref. 57178.
