摘要: We report the effect of transport stress on the immune responses of the sea cucumber Apostichopus japonicus. The total coelomocytes counts, phagocytosis activity, reactive oxygen species production, acid phosphatase activity, phenoloxidase activity and catecholamine levels were measured in A. japonicus following both damp and water transportation methods. With both transport methods, stress resulted in significant elevation of catecholamine levels. Total coelomocytes counts increased following transportation, whereas phagocytic activity and reactive oxygen species production decreased. Damp transport significantly depressed acid phosphatase and phenoloxidase activity in A. japonicus. However, there were no significant differences in acid phosphatase and phenoloxidase activity after water transportation. These results show that transport stress induces modifications in the immune system of A. japonicus and that damp transport elicited more severe stress than water transport. This study increased understanding of the mechanism of transport stress inducing neuroendocrine responses and immune modification in A. japonicus. The information obtained should be helpful to optimize transport process in sea cucumber culture.
