合浦珠母贝(Pinctada fucata G.)在养殖过程中,无论是母贝养殖期或育珠期,都有大量死亡,有的死亡率高达90％左右。其原因,前几年主要是由多毛类的凿贝才女虫(Polydora ciliata)凿穿贝壳的继发性脓疡(俗称“黑心肝病”)所引起的,现已基本得到控制。近年来附着物对合浦珠母贝的危害是造成贝体生长不良和死亡的重要原因之一。 Pinctada fucata G. has a large number of deaths during the breeding process, both during the breeding period and during the fertilization period. Some death rates are as high as 90%. The reason, a few years ago mainly caused by the polychaete Polydora ciliata scalded shellfish secondary abscess (commonly known as “black heart and liver disease”) has been basically controlled. In recent years, the attachment of Hepu pinball harm is one of the important reasons for poor growth and death of shellfish.
