Abstract

Background and Objective: Clarias gariepinus with the common name “African catfish” is one of the most important tropical catfish species for aquaculture in Nigeria. It is widely cultured in Nigeria. However, one of the major difficulties being faced in most fish hatcheries and production farms is infectious diseases. Therefore, this research was conducted on the haematology and proximate composition of three population groups of C. gariepinus to identify a hardier population group that can be recommended for such genetic modifications. Materials and Methods: The haematology and proximate analyses of Clarias gariepinus were carried out on these ecotypes for the wild and cultured systems. An automated blood analyser was used for the haematological analysis, while the proximate analyses were carried out following the standard laboratory protocol of the National Institute of Freshwater Fisheries Research, New Bussa. Results: The results revealed variations in the blood composition of the C. gariepinus population groups studied and both the environmental and genetic references indicated that population group A (wild) is superior to the other two population groups B and C (pooled cross and Dutch) having a highest significant mean value of Mean Corpuscular Haemoglobin Concentration (MCHC) alongside other parameters and was therefore recommended for the improvement of the cultured stocks. Conclusion: This research concludes that there is variation in the blood composition of the C. gariepinus P. Groups studied and both the environmental and genetic references indicated that the P. Group A is superior to the other two. P. Groups B and C had the highest significant mean value of Mean Corpuscular Haemoglobin Concentration (MCHC).
