In this study, we aimed to explore the biological characteristics and quality of crayfish () reared in different modes and fill in the research gap regarding assessments of 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 acids, free amino acids, and mineral elements of . Extremely significantly higher CP (32.50%) but lower HSI (6.22%) and MY (9.54%) were observed in reared in the RCCC compared with those reared in the PC. The RCCC contained higher levels of total lipids, ∑MUFA, ∑EFA, h/H, ∑EFAA, ∑FAA, ∑TUV, ∑TBV, and ∑TME but lower levels of crude protein, ∑SFA, DHA + EPA, DHA/EPA, AI, and ∑TSV in the hepatopancreas. In addition, the RCCC had higher levels of ∑SFA, ∑EFA, AI, TI, ∑EFAA, ∑FAA, ∑TUV, and ∑TBV but lower levels of ∑HUFA, ∑n-6 PUFA, DHA/EPA, h/H, ∑TSV, and ∑TME in muscle. In summary, the culture modes of reared in the cold regions of China have an influence on the biological characteristics and quality of this species.
在本研究中，我们旨在探究不同养殖模式下小龙虾的生物学特性和品质，并填补中国寒冷地区小龙虾品质评估方面的研究空白。为此，在中国东北地区建立了典型的稻虾共作（RCCC）和池塘养殖（PC）模式，以评估小龙虾的螯比例（CP）、肝体指数（HSI）、腹部肉产量（MY）、常规成分、脂肪酸、游离氨基酸和矿物质元素。与池塘养殖的小龙虾相比，稻虾共作模式下养殖的小龙虾螯比例显著更高（32.50%），但肝体指数（6.22%）和腹部肉产量（9.54%）更低。稻虾共作模式下养殖的小龙虾肝胰腺中总脂、∑MUFA、∑EFA、h/H、∑EFAA、∑FAA、∑TUV、∑TBV和∑TME含量较高，但粗蛋白、∑SFA、DHA + EPA、DHA/EPA、AI和∑TSV含量较低。此外，稻虾共作模式下养殖的小龙虾肌肉中∑SFA、∑EFA、AI、TI、∑EFAA、∑FAA、∑TUV和∑TBV含量较高，但∑HUFA、∑n-6 PUFA、DHA/EPA、h/H、∑TSV和∑TME含量较低。综上所述，中国寒冷地区小龙虾的养殖模式对该物种的生物学特性和品质有影响。
