THE EVALUATION OF GROUNDWATER QUALITY ON SUCCESSFUL HATCHERY CULTURE OF AFRICAN CATFISH (CLARIAS GARIEPINUS) IN IKWUNO OBORO, ABIA STATE

*Nwakanma C. and Okwum C

Abstract

Groundwater samples were taken from Oboro community to evaluate the hatchability and survivability of African Catfish (Clarias gariepinus) broodstock of average weight 1.16kg for male and 1.15kg for female. The percentage (%) fertility and hatchability was determined subjectively after 12hours of fertilization. Survival percentage (5) was evaluated for a period of 2 – 3 weeks and post hatching survivability was calculated. pH, Temperature, Alkalinity, Dissolved Oxygen and Salinity were calculated using standard measurement for significance differences. The result for percentage survival rate and percentage hatchability rate of Clarias gariepinus fry in this study were not within acceptable range and were not significantly different (P > 0.05).
