摘　　要：在实验室内进行了暖冬、海水温度和盐度对菲律宾蛤仔体内寄生帕金虫数量变化影响的实验,结果表明,在冬季高于自然海水温度的各实验组中菲律宾蛤仔体内的帕金虫含量要高于自然海水温度实验组,并且显示出菲律宾蛤仔体内过冬的帕金虫于春末和夏初当海水温度达到20℃左右时又出现明显增高趋势,导致菲律宾蛤仔的死亡率显著提高;盐度实验结果表明,在温度相同情况下,20~24的盐度是菲律宾蛤仔体内帕金虫的最适繁殖盐度。针对实验结果,提出了预防菲律宾蛤仔的帕金虫病害的一些生态养殖措施。The clam Ruditapes phillippinarum is a commercial product and one of the most important shellfishes in sand beaches and tidal flats along the coast of China.Endoparasite Perkinsus atlanticus was confirm to be one of harmful pathogen in the clams.The experiments of clam infected by perkinsus atlanticus were conducted in warm water at 2,4,8℃ over nature temperature for 7 months from winter to summer.The results showed that the clams Perkinsus atlanticus prevalence in all of warm water was significant higher t...
