Biology: |
Requires standing or slow-flowing conditions such as in impoundments or the backwaters of large rivers. Feeds on phytoplankton and zooplankton (Ref. 30578, 10294). In its natural range, it migrates upstream to breed; egg and larva float downstream to floodplain zones. An active species well known for its habit of leaping clear of the water when disturbed (Ref. 7248). Swims just beneath the water surface (Ref. 5258). Utilized fresh for human consumption and also introduced to many countries where its ability to clean reservoirs and other waters of clogging algae is appreciated even more than its food value (Ref. 9987). It is among 3 or 4 species of cyprinids whose world production in aquaculture exceeds 1 million tons per year (Ref. 30578). Larvae and small juveniles feed on zooplankton; from 15mm SL only feeds on phytoplankton. Very sensitive to low temperature (below 5�C) and oxygen deficit. (Ref. 59043).
