Biology     Glossary (e.g. epibenthic)

Adults are found in the shore and open oceanic waters, in schools. They feed mainly on fish larvae and small crustaceans. Marketed fresh (Ref. 9283). Utilized canned for human consumption and also made into fishmeal (Ref. 9988). The species is often found in Juan Fernández Is. as an incidental catch of Pseudocaranx chilensis (Guichenot, 1848) fisheries (Ref. 89357).
