	<dc:description>Occur in large lowland rivers with backwaters and also in eutrophic lowland lakes.  Feed mainly on zooplankton in open water of backwaters and other still water bodies.  Spawn along shores of rivers or in backwaters on submerged vegetation and also on gravel in moderate current.  Migrate upriver in long distances to suitable spawning sites.  Juveniles stay in backwaters and flooded zones along rivers.  Enter freshened parts of seas to forage.  Life span reaches more than 10 years.  Locally threatened by habitat alterations along river banks (Ref. 59043).</dc:description>
