利用常规核型分析、C-带、Ag-NORs、DAPI荧光染料染色以及几种重复序列（5SrDNA、18SrDNA和(TTAGGG)n）的荧光原位杂交技术对斜带石斑鱼E.coioides、青石斑鱼E.awara、拟青石斑鱼E.fasciatomaculosus、赤点石斑鱼E.akaara、褐石斑鱼E.bruneus和镶点石斑鱼E.amblycephalus的核型特征进行描述比较和研究，结果如下： 1、6种石斑鱼二倍体染色体数目均为48，但其染色体组组成具有一定的差异，核型公式分别为：斜带石斑鱼2n＝48，2sm＋46t，NF＝50；青石斑鱼2n＝48，48t，NF＝48；拟青石斑鱼2n＝48，1s...Using Giemsa-staining, C-band, Ag-NORs, DAPI staining and Fluorescence in situ hybridization (FISH) with repetitive sequencing (5S rDNA, 18S rDNA, and (TTAGGG)n ) techniques, I studied the karyotypic characteristics of Epinephelus coioides、E. awara、E. fasciatomaculosus、E. akaara、E. bruneus and E. amblycephalus. The results are as following: 1．All six species presented uniform diploid numbers...学位：理学博士院系专业：海洋与环境学院海洋学系_海洋生物学学号：B20042701
