ABSTRACT

A study of the haernatological parametts and indices (haemoglobin haematocrit, erythrocytes count, leucotes counts, mean corpuscular volume, mean corpuscular. Hemoglobin, mean corpuscular 1.1amoglnin conI centration) is reported for four freshwater pond-raised fish species (Oreochromis niloticus, Tilapia zulu, Clarias gariepinus, hybrid (61arias gariepinus X HaUerobranchus longifilis) collected from the fish farm colex ofederal University of Agriclture Umudike and wild sourced hryichthys nigrodigitatus collected from the Umuopara section of the Imo river. The range and mean values of all the haematological parameters and indices of the fish species studied were determined... Significant differences(P
