| 摘 要： | 2001—11-2002—05的鄱阳湖候鸟保护区淡水壳菜对双壳类的感染情况调查显示，淡水壳菜对双壳类的感染具有普遍性，扭蚌、背瘤丽蚌、洞穴丽蚌、猪耳丽蚌等种类的感染率较高，所有个体的平均感染率为35．3％；不同的个体间，感染强度的变化比较大，所有被感染个体的平均感染强度为6．6；感染强度≥10的个体仅占被感染个体的18．4％；淡水壳菜主要寄生在双壳类的壳顶和进、出水管附近。

| Abstract: | Incidence of zebra mussel, Limnoperna lacustris, on the bivalve mussels, was investigated in Poyang lake area, from November, 2001 to May 2002. The adverse effects of zebra mussel on bivalves were also evaluated by comparing the infected and uninfected mussels. The investigations revealed that the infestation of zebra mussel on bivalves was prevalent, the infestation percentage of Arconaia lanceolata?Larnprotula leai,Larnprotula caveata and Larnprotula rochechouarti were much higher, average infestation percentage for all individuals was 35.3%; The infection intensity changed significantly among different individuals, which of only a few individuals (18.4%) was in excess of ten, average infection intensity for all individuals was about 6.6. The results also suggested that bivalve mussels were infected by Limnoperna lacustris mainly on apex or incurrent and excurrent siphon. |
