Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-West Pacific: African southeast coast from Cape of Good Hope to southern Mozambique; northern Indian Ocean off Pakistan and northwest coast of India; northern Pacific from southern Korea and Japan, along the Chinese coast to Hong Kong; in Australia along the entire southern seaboard from North West Cape (north of Shark Bay) in Western Australia to the Burnett River (north of Brisbane) in Queensland.

Biology     Glossary (e.g. epibenthic)

Adult fish found mainly near shore beyond the surf zone, occasionally going inshore. Juveniles exclusively found inshore. Juveniles recruit to estuaries at about 30 cm TL. An important food fish (Ref. 11025).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00536 - 0.01702), b=3.07 (2.92 - 3.22), based on LWR estimates for species & (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.5   ±0.6 se; Based on diet studies.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (tm=6; tmax=40; K=0.03-0.24; Fec=900,000-1 million).
Vulnerability (Ref. 59153):  Very high vulnerability (77 of 100) .
Price category (Ref. 80766):   Medium.
