or around islands where reefs are well developed. Eggs and larvae are pelagic for two to three weeks. Spawning occurs not more than 30km from shore. Older larvae migrate
inshore to settle in coastal wetlands (mangroves and estuaries). Sub-adults return to sea to mature. Larvae eat zooplankton. Juveniles and adults eat cyanobacteria, soft
algae, small benthic invertebrates, and pelagic fish eggs and larvae.
Fishery Status:
This species is not protected or subject to fishery regulations. It is bycatch in the net fishery, but is a relatively uncommon component of the catch. It is considered a
poor quality fish on the local market.
