| | INTEGRATED FISH FARMING IN CHINA |
 | | Silver carp, bighead, grass carp, fl carp, and common carp, with their larger size and speedy growth, are the dominant cultured species for polyculture in integrated fish farms. |
 | | Crucian carp, wuchang fish, and mud carp, however, owing to their smaller size and slower growth, are usually regarded as secondary species for polyculture. |
 | | Common carp and crucian carp spawn from the end of March to early April in central and central eastern part of China, from April to May in northern China, and in June in northeastern China; however, spawning begins as early as late December in the Pearl River basin. |
