Biology     Glossary (e.g. epibenthic)

Adults prefer clear oceanic waters around islands to neritic waters (Ref. 5217). Occasionally in turbid waters (Ref. 9283). Pelagic (Ref. 58302). Individuals travel in compact groups of hundreds of thousands of fish. Mainly nocturnal in habit, they disperse at night to feed on small shrimps, benthic invertebrates, and forams when inshore, and zooplankton and fish larvae when offshore (Ref. 9283, 90102). Marketed fresh and salted or dried (Ref. 9283). Reported to reach 70 cm TL (Ref. 48635).

IUCN Red List Status (Ref. 115185)

Threat to humans
