Maturity: Lm ?  range ? - ? cm Max length : 45.0 cm SHL male/unsexed; (Ref. 348); common length : 15.0 cm SHL male/unsexed; (Ref. 348)

Biology     Glossary (e.g. epibenthic)

A major commercial species. Introduced for aquaculture in many countries. However experimental plantings in tropical western Pacific Islands often failed, apparently because of the sustained high temperature of the water (Ref. 348).

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (K=0.01-2.69).
Prior r = 0.57, 95% CL = 0.37 - 0.85, Based on 3 stock assessments.
Vulnerability (Ref. 71543): Low to moderate vulnerability (35 of 100).
Price category (Ref. 80766): High.
