There are three major types of marine finfish farming systems in China: indoor
culture, pond culture and cage culture, and the culture techniques used in these systems
are being refined continuously. The indoor culture of marine finfish is found mainly
in Shandong and Liaoning provinces around the Yellow and Bohai seas in northern
China. The major species groups cultured are flatfishes, breams and puffer.
