【摘要】 于 1997年 3月至 1998年 6月期间 ,在广东省珠海、深圳和廉江龙营围等地方的虾塘进行浮游动物种类的调查 .结果表明 :在虾塘浮游动物的优势种类有小长腹剑水蚤 (Oithonanana)、双齿许水蚤 (Schmackeriaduia)、小拟哲水蚤 (Paracalanuscrassirostris)、捷氏歪水(Tortanusderjugini)、琉球咸水剑水蚤 (Halicyclopsroyi)、刺尾纺锤水蚤 (Acartiaspinicauda)、海洋伪镖水蚤 (Pseudoiaptomusmarinus)、壶状臂尾轮虫 (Brachionusurceus)、多毛类幼体 (Polychaetalarva)、短尾类幼体 (Brachyuralarva)和各种桡足类的幼体 (Copepodalarva) .浮游动物的非优势种类有圆囊箭虫 (Sagittajabarensispathansalis)、肥胖箭虫 (Sagittaenflata)、模式有瓜猛水蚤(Onycholamptusmobammed)、孔雀唇角水蚤 (Labiadoceradubia)、驼背隆哲水蚤 (Acrocalausgibber)、短角异剑水蚤 (Apocyclopsroyi)和左突唇角水蚤 (Labidocerasinilobata)等种类 .属于甲壳类动物的猛水蚤例如模式有瓜猛水蚤 ,由于以虾塘动物尸体为食 ,则有可能因摄食患白斑病死亡的对虾而感染上白斑综合症病毒 (whitespotsyndromevirus ,WSSV) ,成为WSSV的自然宿主 .更多还原

【Abstract】 The results of investigations on species of zooplankton in the prawn pond show: The dominant species of zooplankton were Oithona nana,Schmackeria duia,Paracalanus, Tortanus derjugini,Halicyclops royi,Acartia spinicauda,Pseudoiaptomus marinus,Brachionus urceus,Polychaeta larva,Brachyura larva,Copepoda larva and the non dominant species of zooplankton were Sagitta jabarensis pathansalis,Sagitta enflata, Onycholamptus mobammed,Labiadocera dubia,Acrocalaus gibber, Apocylops royi,Labidocera sinilobata in the prawn pond of Zhuhai and Shenzhen and Lianjiang Longyingwei Because some species of zooplankton such as Onycholamptus mobammed, Ostracod and Cyclopoida are predators or scavengers, these species of zooplankton may be WSSV hosts更多还原
