Population genetic structure and phylogentic analysis for Morone americana in Delaware Bay of United States [PDF]
, 2016 美洲狼鲈(Moroneamericana，Gmelin，1789)隶属于鲈形目(Perciformes)，狼鲈科(Moronidae)，狼鲈属(Morone)，别名美洲白鲈、白石鮨。美洲狼鲈是在美国东海岸浅海区域十分常见的一种溯河洄游鱼类，每逢春末夏初，生活于近海和河口区域的美洲狼鲈便溯河洄游至河流中上游产卵繁衍。美洲狼鲈也经常被用作海区污染程度的指示种。鉴于美洲狼鲈广泛的分布范围以及巨大的种群数量，其十分适合作为近岸洄游性鱼类群体研究的模式种类。同时，其在检测环境污染方面也具有主要作用 ...

, 2010 为认识我国淡水鱼类烂鳃病的病原以及柱形病在我国的发生情况,实验从发生烂鳃病的病鱼中分离细菌性病原,经过生理生化特性分析以及是否在含托普霉素的Shieh培养基中生长并形成黄色假根状菌落,是否产生降解明胶和硫酸软骨素的酶类等特性的鉴定,并结合16SrDNA序列分析,证实柱状黄杆菌(Flavobacterium columnare)是所分离的烂鳃病的病原。同时,研究也证实20世纪曾经命名为烂鳃(Gill-rot)病病原的鱼害黏球菌(Myxococcus piscicola Lu,Nie & Ko,1975 ...
