Inhabits coastal waters and often comes near the surface at night. Feeds on a variety of small fishes and crustaceans (chiefly on prawns and species of Setippina, Anchoviella, Harpodon, Trichiurus etc. in Hooghly estuaries in India). Caught mainly with shore seines, bagnets and coastal bottom trawls in Asian countries. Marketed fresh and iced as well as dried salted.
