Size:

Maturity: Lm unknown. Range unknown. Max Length: 210cm TL. Commonly to 100cm TL. 


Habitat and Ecology:

Pelagic, inhabiting open waters, but also approaches the coast (depth 0-85m, usually 5-10m). Forms schools. Follows ships and forms small concentrations below floating objects and prone to FAD fishing techniques. Feed on almost all forms of fish and zooplankton; also takes crustaceans and squid. Spawn in the open sea and probably approximate to the coast when water temperature rises. Eggs and larvae are pelagic. In East African waters, spawning season may last from March to early June and spawning occurs inshore. In tropical regions spawning likely occurs year round.


Fishery Status:

This species is not protected or subject to fishery regulations. It is caught primarily by trolling. It is a regular but not numerous component of the catch.
