| 摘 要： | 用聚丙烯酰胺凝胶水平电泳分析了吉富、“埃及”、“７８”、“８８”及“美国”五个品系尼罗罗非鱼的生化遗传特征。不同品系尼罗罗非鱼在肝脏ＥＳＴ同工酶的表型上有明显差异。Ｅｓｔ－２谱带为吉富和“埃及”品系所特有，可作为与其他品系尼罗罗非鱼区分的遗传标志。

| Abstract: | Biochemical genetic characteristics of GIFT (Genetic Improvement of Farmed Tilapia) strain, "EGYPT" strain, "78" strain, "88" strain and "AMERICA" strain of Nile tilapia (Oreochromis niloticus) were analysed by polyacrylamide gel electrophoresis.The result showed that there were significant differences of phenotype of Est in the liver among different strains. Est-2 was only found in GIFT strain and "EGYPT" strain, which could be used as a genetic marker to differentiate these strains of Nile tilapia. |
