| Biology: |
The fisheries have grown exponentially in the last 30 years, with resulting declines in population and area closures. The species has been included on appendix 2 of CITES (Convention on the International Trade of Endangered Species). International trade is allowed only from nations in which the populations of the species are not under threat from commercial fishing (Ref. 355). Maximum weight from Ref. 97674 cited in Ref. 105296. This species is found intertidal and offshore, on coral reefs, particularly on algae, coral sand, and seagrass habitats (Refs. 355, 83934). Adults prefer sandy algal flats; also found on gravel, coral rubble, smooth hard coral and beach rock bottoms. Rarely on soft bottoms of mud and/or silt. Benthic grazer. Feeds on diatoms, seagrass detritus, and various algae and epiphytes. Nocturnal (Refs. 105087, 127891) (Ref. 355). |
