Physical characteristics of the blood plasma of Labeo ruddi and Labeo rosae (Pisces: Cyprinidae).
1. The physical composition of blood plasma of Labeo ruddi and Labeo rosae males were determined during the breeding and post breeding phases. 2. The mean values for most blood electrolytes, pH and osmolality of the two species showed the same variation as was found for other cyprinids. 3. The ability to handle stress may be reflected in the presence of certain electrolytes in the blood and efforts are made to relate differences in the concentration of these parameters to interspecies differences between L. ruddi and L. rosae.
