Highighted items on the list are where Pagrus auratus may be found.
Remarks Found on the continental shelf (Ref. 75154). Juvenile snapper leave the midwater zone to inhabit reefs or rocky outcrops when they are 12 months of age and about 6 cm long (Ref. 6390). They are most abundant in seagrass beds and are also associated with reef and gravel areas (Ref. 30572). As they grow, they move into deeper water and aggregate on near inshore reefs (Ref. 30572). In New Zealand, juvenile snapper (less than 25 cm FL) are caught in water 0-25 m deep (Ref. 30575). In southern Australia, juvniles and post-flexion larvae enter estuaries at floodtides (Ref. 30576). In New South Wales, Victoria and South Australia, the older juveniles and young adults progressively move to coastal and offshore waters and some individuals also migrate substantial distances along the coastline (Ref. 6390).
