Survival and Metabolic Modulation of Swimming Crab Portunus trituberculatus During Live Transport

Demand from consumers for small quantities of live swimming crab Portunus trituberculatus is rising with the development e-commerce. However, it challenging to keep P. alive post-capture. In this study, a transport bag containing oxygen and seawater (24 ppt) was used investigate survival metabolic changes during transport. The results showed that more than 80% could survive at least 24 h in bag. ability crabs may be attributed adaptive metabolism, as suggested by switch an aerobic anaerobic pathway energy generation decline amino acid nucleic osmoregulation. Our findings suggest effectively extend post-capture time . Metabolic adaptation – especially homeostasis crucial study provides promising method
