摘要

一项来自尼日利亚西南部咸淡水和淡水栖息地的Sarotherodon melanotheron (Ruppell)的比较种族研究使用形态计量学和分生性状来确定变异，结果表明它们是同一物种的表型可分离种群。结果表明，鱼体深度、尾柄深度、鳃耙数和侧线鳞数差异显著(P < 0.05)，这可能是由于两种水体的温度、盐度和底质不同造成的。结果还表明，淡水亲鱼可能比咸淡水种群更适合育种计划。

Morphometric Variations in Sarotherodon melanotheron (Pisces: Cichlidae) from Brackish and Fresh Water Habitats in South-western Nigeria

A comparative racial study of Sarotherodon melanotheron (Ruppell) from brackish and fresh water habitats both in south-western Nigeria using morphometric and meristic characters to determine variations showed that they were phenotypically separable populations of the same species. The results revealed significant differences (P < 0.05) in body depth, caudal peduncle depth, number of gill rakers and scales on the lateral line which were suggested to have occurred as a result of difference in the temperature, salinity and substratum in the two water bodies. The results also implied that fresh water broodstock could be preferable to the brackish population for breeding programmes.
