The Indian threadfin (Leptomelanosoma indicum) is a species of marine ray-finned fish from the family Polynemidae, the threadfins. It is a coastal species from south-east Asia which has been recorded in Papua New Guinea.
The Indian threadfin has been confirmed as occurring in the coastal waters of southern Asia from Pakistan to Borneo. In Papua New Guinea there is a single record of a specimen taken in Kerema Bay in the Gulf of Papua. Records from Africa are unconfirmed and not now regarded to be of this species.
The Indian threadfin is found over shallow muddy and sandy substrates on the continental shelf, especially in the vicinity of estuaries and it is known to enter rivers. It is carnivorous and the largest part of its diet is small benthic crustaceans, such as prawns and crabs, and small fishes. The amount of fishes taken increases as the fishes grow larger. It has been taken from as deep as 100 metres (330 ft) but rarely below 55 metres (180 ft). In a sample taken off India 40% of the fish caught were hermaphrodites, 19.3% were males and 41% were females. They spawn in two main periods, April to June and October to November, with the main breeding season being April to June. However, in southern India spawning was in October and November.
