Hematological studies on some Nile fishes, Tilapia nilotica, Lates niloticus, and Labeo niloticus

Abstract

Hemoglobin content of 3 Nile fishes - Tilapia niloticaLinnaeus, Lates niloticusLinnaeus and Labeo niloticusForskal- were examined. Clear differences in hemoglobin and hematocrit values were observed, and seasonal variation in the hemoglobin content of Lates niloticus and Labeo niloticus were noticed. There is a correlation between hematocrit value and hemoglobin content of the 3 species examined. The chloride content is higher in the species with lower hemoglobin content. © 1972 Springer-Verlag.
