Carangid

The total catch in 1976 was probably about 3.5 million tons and was mainly composed of pelagic species such as sardines, mackerels and various carangids.

Carangids occur in a variety of habitats: coral and rocky reefs, in the surf along sandy beaches, and in estuaries.[…]Most carangids are swift predators, and the larger species are prized as sport fish and for their excellent eating qualities.

Carangids may use DMSP as a cue to locate productive areas for foraging. Carangids generally feed on smaller fish, shrimps, and other invertebrates (Böhlke and Chaplin 1993).
