Biological Characteristics and Chemical Composition of Crayfish (Procambarus clarkii) Reared in Two Different Culture Modes in Cold Regions of China

In this study, we aimed to explore the biological characteristics and quality of crayfish (Procambarus clarkii) reared in different modes and fill in the research gap regarding assess- ments of Procambarus clarkii quality in the cold regions of China. To achieve this, typical rice–crayfish coculture (RCCC) and pond culture (PC) modes were established in Northeast China to evaluate the chelae proportion (CP), hepatosomatic index (HSI), abdominal meat yield (MY), proximate composition, fatty...
