Description

The kawakawa or mackerel tuna is a tuna-like fish of the mackerel family (Scombridae) from the Indo-Pacific. The species grows to about one metre and has a streamlined, torpedo-shaped body with a blue-green back with a pattern of oblique, broken stripes and a few dark spots below the pectoral fin. It occurs in open coastal waters but always stays close to the shoreline; juveniles enter bays. As a fast, powerful predator it hunts small fishes, squid and crustaceans in schools. The kawakawa is an important commercial and sport fish and is harmless to humans.
