📖 Overview

Coastal pelagic . Presumably schooling, inshore and entering estuaries. More precise data needed, based on correct identifications. If this is the species being referred to in Ref. 6841, then the principal food of the young would be prawns and copepods, supplemented by polychaetes and amphipods. Minimum depth range from Ref. 137633.
