Benthopelagic or pelagic in estuaries and coastal waters. Feeds on a wide variety of small fishes and crustaceans chiefly on prawns, young clupeoids, Harpodon nehereus and Trichiurus spp. in Hooghly estuaries, India. Caught mainly with bag nets in estuaries, with shore seines and boat seines in inshore waters, and with trawls in off-shore waters. Marketed fresh as well as dried salted.
