They occur in groups, especially during pre-reproduction migration (Ref. 59043). A long-lived species which also inhabits water bodies on low plains (Ref. 26100). Adults feed on invertebrates, plants and detritus (Ref. 59043). Spawning takes place in April. Threatened due to pollution and the introduction of other species (Ref. 26100).
