A pelagic migratory fish inhabiting coastal waters at depths between 15-200 m; sometimes entering turbid estuarine waters; usually found in small schools (Ref. 9684). Feeds mainly on small schooling fishes (especially sardines and anchovies), squids and crustaceans (Ref. 9684). Fishing peaks in the months of November and December in Eastern Thailand, late Dec and January in the northern part of the Gulf and January to March in its western part. Caught with midwater trawls, purse seines, bamboo stake traps, and by trolling (Ref. 9684). Marketed mainly fresh; also dried-salted (Ref. 9684), smoked and frozen (Ref. 9987). Small quantities of frozen product are exported to Europe and North America (Ref. 9987).
