Body shape (shape guide): elongated.
Inhabit deep water offshore on sandy mud bottom for most of the year, but also gathers in large shoals in deltas of rivers to feed during monsoons (Ref. 9987, 11230). Spawn 6 batches of broods per year (Ref. 43449). An aggressive predator (Ref. 9987). Primarily caught along Maharashtra with the bag-net, better known as 'dol' net. Operation of this gear is timed to a strong tidal current. The bag with the mouth set against the current strains the fish which is being retained therein by the strength of the current. The net is thus retrieved before the tide turns. Very phosphorescent. Excellent food fish. Marketed fresh and dried or salted; consumed pan-fried (Ref. 9987).
