( 1972 ) 5 Acrosin Activity of Spermatozoa in Spermathecae of Scylla serrata GUAN Weibing, WANG Guizhong, LI Shaojing, CHEN Jingmin ( Department of Oceangraphy, Institute of Subtropical Oceanography, Key Laboratory for Marine Environmental Science of the Ministry of Education, Xiamen University, Xiamen 31005, Fujian, China ) AbstractAcrosin, a sperm-specific arosomal proteinase, has an essential role in the fertilization process and is thought to be important in the acrosome reaction, sperm-zona binding and zona penetration. The spermatozoa acrosin activity of Scylla serrata is measured with a simplified clinical assay of total sperm acrosin activity. This method is based on the measurement of amidase activity of sperm suspensions. The acrosin activity assay has been used in many animals. Results of these studies indicated that use of this assay method could provide valuable information concerning semen quality. The spermatozoa acrosin activity of Scylla serrata is about 3.5µIU/10 and 4.248µIU/10. The acrosin activity is lower than some mammals such as boars, human beings and horses. It shows that the significant difference between acrosin activity of different kinds of species and also reflect the spermatozoa of Scylla serrata may survive with the restraining state in spermathecae. This result indicates that the clinical assay of acrosin activity can be used for crab spermatozoa to evaluate the quality of crab semen. KeywordsScylla serrta; acrosin; spermatozoa; spermathecae
