- Remarks: Auxis thazard is a major fishery in the Maldives. It is third in importance in terms of catch after skipjack and yellowfin tuna. Caught mainly by pole and line, but also by trolling. It is not as a popular food fish as skipjack, perhaps because of its small size, boniness, and possible confusion with the poisonous “raagondi koli�? (see page 372).
