Biology     Glossary (e.g. epibenthic)

Adults demersal on the continental shelf and upper slope (Ref. 9563) to depths of 450 m (Ref. 33616). Juveniles tend to live near shallow reefs (Ref. 6390). Postlarvae inhabit offshore waters and are found in surface waters at night (Ref. 9072). Average weight is 1800 g. Feed on polychaete worms, crustaceans, mollusks and echinoderms (Ref. 28626). Flesh is quite good eating. Often sold as tiki fillets.

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01620 (0.01205 - 0.02178), b=3.04 (2.95 - 3.13), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.42 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.1-0.28; tm=3-6; Fec=100,000; tmax=50).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100) .
Price category (Ref. 80766):   High.
