随着电子商务的发展，消费者对少量活梭子蟹的需求不断增加。然而，在捕获后保持三疣梭子蟹存活具有挑战性。本研究采用一个装有氧气和海水（24 ppt）的运输袋，研究了三疣梭子蟹在运输过程中的存活和代谢变化。结果表明，80%以上的三疣梭子蟹在运输袋中能存活24 h以上。蟹类的生存能力可能归因于适应性代谢，如从有氧到厌氧的能量产生途径的转换以及氨基酸代谢、核酸代谢和代谢调节的下降所表明的。研究结果表明，运输袋能有效延长三疣梭子蟹捕获后的存活时间。代谢适应-特别是能量平衡-对螃蟹在运输过程中的生存至关重要。本研究为三疣梭子蟹活体运输提供了一种可行的方法。
Demand from consumers for small quantities of live swimming crab Portunus trituberculatus is rising with the development of e-commerce. However, it is challenging to keep P. trituberculatus alive post-capture. In this study, a transport bag containing oxygen and seawater (24 ppt) was used to investigate the survival and metabolic changes of P. trituberculatus during transport. The results showed that more than 80% P. trituberculatus could survive at least 24 h in the transport bag. The ability of the crabs to survive may be attributed to adaptive metabolism, as suggested by the switch from an aerobic to an anaerobic pathway for energy generation and a decline in amino acid metabolism, nucleic acid metabolism, and osmoregulation. Our findings suggest that the transport bag could effectively extend the post-capture survival time of P. trituberculatus. Metabolic adaptation – especially energy homeostasis – is crucial for crab survival during transport. Our study provides a promising method for the transport of live P. trituberculatus.
