Annual changes of immune enzymes in coelome fluid of sea cucumber, Apostichopus japonicus
刺参体腔液几种免疫指标的周年变化

In view of eco-immunology, immune enzymes in coelome fluid of sea cucumber, Apostichopus japonicus, were investigated from July in 2006 to June in 2007. The data showed that turing points of enzyme changes were in September, October, January, February, April and May. The results showed that immune characters in coelomic fluid of A. japonicus might not solely be attributed to temperature and salinity. These data were complex and interesting. Considering the life characters of A. japonicus, the significant changes of enzymes activity might be associated with growth, reproduction, aestivation, and environment.
