Habitat and Ecology
Common in streams where the flow is somewhat moderate. Streams typically have a substrate of boulders. Predominantly inhabits freshwater, migrating up to torrential streams. Probably breeds in freshwater (Menon 1999). Also known from estuaries and brackish waters (Talwar and Jhingaran 1991, Bijukumar and Sushama 2000).

Migration

Learn more about this article

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Justification

Sicyopterus griseus is assessed as Least Concern in view of its wide distribution, presumed large overall population, it occurs in some protected areas, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Major Threats
Since S. griseus is known to occur in low and midland areas of most rivers in Kerala, as well as some estuaries, which are undergoing decline in their habitats due to pollution, sand mining, destructive fishing and construction of barrages and check dams, there is ever reason to believe that this species may be affected.
