摘　　要：选用了罗非鱼、黄颡鱼和鳙鱼作为圆背角无齿蚌的寄生鱼,并对寄生效果进行了分析,结果表明:罗非鱼的平均寄生量达2045只/尾,黄颡鱼287只/尾,花鲢为220只/尾;在寄生过程中,罗非鱼成活率高达100%,黄颡鱼为60%,花鲢仅为30%;圆背角无齿蚌钩介幼虫在水温为(19±1)℃的条件下,变态期为11￣19d。罗非鱼为圆背角无齿蚌的最佳寄主。本研究结果将用于指导圆背角无齿蚌规模性的人工繁殖生产。Oreochromis nilotica, Pseudobagrus fulvidraco and Aristichthys nobilis were selected as host fish for A nodonta woodiana pacifica in this study.The effect of infestation resulted that average infesting juveniles 2045 individuals/tilapia,287 individuals/Yellow headed catfish and 220 individuals/Bighead carp. The survival rate of hosts reached 100 % （tilapia）, 60 % （Yellow headed catfish） and 30 % （Bighead carp） respectively. Glochidia metamorphous period varied from 11 days to 19 days with water temperature （19＋1） %, Results indicate that Tilapia is the best host for Anodonta woodiana pacifica compare to others,which can be applied to the large-scale propagetion production of A nodonta woodiana pacifica in the large-scale production.
