Comparative physiology of three ecologically distinct freshwater fishes, <i>Alestes nurse</i> Ruppell, <i>Synodontis schall</i> Broch &amp; Schneider and <i>Tilapia zillii</i> Gervais

Abstract

There are species differences in the physiological robustness of Alestes nurse, Synodontis schall and Tilapia zillii. The values of coefficient of condition in the Alestes sp., Synodontis sp. and Tilapia sp. were 1·74,2·48 and 3·6 respectively. Tilapia zillii was significantly more robust than any of the other two species ( P &lt;0–02).
