Effects of cold stress-induced dormancy methods on life characteristics and nutritional quality indexes of Patinopecten yessoensis during anhydrous living-preservation

Exploring the best method to induce the dormancy of scallops（Patinopecten yessoensis） before live transport can provide a theoretical basis for their survival and circulation.

Summary:Exploring the best method to induce the dormancy of scallops（Patinopecten yessoensis） before live transport can provide a theoretical basis for their survival and circulation. Referring to the actual industrial circulation, we treated the samples by three methods of natural cooling of crush ice, acute continuous cooling and gradient cooling, so as to explore the effects of different cooling and dormancy methods on the survival rate, life characteristics and nutritional quality of scallops during anhydrous living-preservation. The results show that the survival rate of the gradient cooling group was 93.33% after 3 d of keeping alive at 4 ℃, significantly higher than that of the acute and natural cooling groups. In the process of cooling dormancy, regular electrocardiogram could not be detected in the natural and acute cooling groups due to the sudden temperature change, and the heart rate in the gradient cooling group showed a regular slow decline. During the live transport, the heart rate in each group showed
