In this article, the immune functions were discussed in three different groups of the abalone, Haliotis diversicolor supertexta, and the results showed that they had a clear difference both in cellular immunity and humoral immunity functions. The degrees of cellular immunity funct ions and humoral immunity funct ions of the rejuvenative abalones were higher obviously than that of the degenerative abalones. Comparing with the wild group of abalones, the rejuvenative abalones had some higher degrees in cellular immunity functions, and obviously lower degrees in humoral immunity funct ions. With phagocytosis the hemocytes of the abalones had a respiratory burst and then turned out reactive oxygen intermediate species ( ROIs) . The ROIs were much in relation to the physical state of the abalones themselves and the environmental temperatures and the quantities of the stimulant s. Both cellular immunity functions and humoral immunity functions had a signif icant decrease as the environmental temperature drop from 25bC to 18bC, while the ant ibacterial activities of the degenerative abalones only had a little difference under the two kinds of temperatures. There was some Phenoloxidase in the hemolymph of the abalone, but their activities were low and had little difference within different groups. It could not be conf irmed as a main humoral immune factor of the abalone.
