Abstract

The gene products of 60 protein coding loci in Schilbe intermedius were examined by horizontal starch-gel electrophoresis. Electrophoretic analysis, using muscle and liver tissues, revealed polymorphism at 17 (28.3%) of the loci studied. The average heterozygosity (H) was calculated at 0.029 (±0.009) which is less than values obtained for other fish species. These results suggest that measures should be taken to conserve the genetic variation of this species.

赞比西河水系上游Schilbe intermedius rppel, 1832(双鱼座,Siluriformes)等位酶变异
采用水平淀粉-凝胶电泳技术检测了中间丝蚕60个蛋白编码位点的基因产物。利用肌肉和肝脏组织进行的电泳分析显示,17个(28.3%)位点存在多态性。平均杂合度(H)为0.029(±0.009),低于其他鱼类。这些结果表明,应采取措施保护该物种的遗传变异。
