Schooling in coastal waters and ascending rivers for as much as 1200 km (usually 50-100 km). Migration though is sometimes restricted by barrages. Hilsa far up the Ganges and other large rivers seem to be permanent river populations. Feeds on plankton, mainly by filtering, but apparently also by grubbing on muddy bottoms. Breeds mainly in rivers during the southwest monsoon (also from January to February to March). Artificial propagation has been partially successful in India (Ref. 4832). Known to be a fast swimmer, covering 71 km in one day (Ref. 12203). Marketed fresh or dried-salted.
Breeds mainly in rivers, upstream to about 50 km or even over 1000 km as in the Ganges (younger fishes may breed in the tidal zone of rivers). In some rivers the migration is restricted by barrages; there is some evidence that hilsa far up the Ganges and other large rivers, although migrating upstream to spawn, are permanent river populations that do not descend to the sea. The main breeding season is during the southwest monsoon, with a shorter season from January to February or March.
