摘  要:
采用银染色方法对广西地区奥尼罗非鱼鱼苗体表寄生的车轮虫进行抽样检测,运用国际通用的方法"统一定位法"和"齿体定位描述法"对检测的车轮虫进行形态学描述,发现寄生于广西奥尼罗非鱼幼鱼体表的车轮虫有两种:异齿车轮虫(Trichodina heterodentata Duncan 1977)与紧密车轮虫(Trichodina compacta Van As&Basson,1989),其中紧密车轮虫为国内首次报道,而罗非鱼是国内发现异齿车轮虫的新寄主。

摘  要:
The morphometric characteristics of trichodinians stained by the dry silver impregnation technique were described in the samples collected from tilapia(Oreochromis niloticus×O. aureus)juveniles infected by parasite trichodiniasis in Guangxi province by the uniform specific characteristic system proposed by Lom(1985)and the detailed description of the denticles proposed by Van As and Basson(1989)to study the pathogenic characteristics. Two species of trichodinid ectoparasites(Ciliophora:Perichicha)identified from tilapia juveniles in Guangxi, China are Trichodina heterodentata Duncan 1977 and Trichodina compacta Van As & Basson, 1989.Trichodina compacta Van As & Basson, 1989 is a new species found in China and Trichodina heterodentata Duncan 1977 is the first report on infecting tilapia in China.
