Environment
Freshwater; benthopelagic; potamodromous (Ref. 51243); depth range 5 - ? m
Climate / Range
Temperate; 4°C - 26°C (Ref. 37797), preferred ?; 64°N - 18°S
Distribution
Asia: China. Introduced to numerous countries and has achieved a near global distribution. However, its breeding requirements are very specialized and stocks are maintained by artificial reproduction or continuous importation. Several countries report adverse ecological impact after introduction (Ref. 1739). Often confused with Hypophthalmichthys molitrix (Ref. 59043).
