Eleutheronema tetradactylum, also known as fourfinger threadfin, Indian salmon, blue threadfin, or Rawas, is a threadfin fish of the Polynemidae family.[1] This is a commercially valuable species, known for uses in aquaculture.[1] It occurs mainly over shallow muddy bottoms in coastal waters,[2] often forming loose schools.[3] Adults of this species enter rivers during winter.[3] Adults feed on prawns, fish, and occasionally polychaetes,[4] while juveniles feed on prawns, shrimps, and mysids.[4] This species is vulnerable to overfishing.[5]
