ASSESSMENT OF HATCHABILITY AND SURVIVAL OF AFRICAN CAT FISH (Clarias gariepinus) HATCHLINGS USING MUNICIPAL, BOREHOLE AND LAKE WATER

African catfish Clarias gariepinus broodstock was subjected to induced breeding in three
different water sources (Lake Water KLW, Municipal Water MNW and borehole Water NBW).
Each water source was triplicated and 11,200 eggs were incubated in the water. Water quality
(pH, dissolved oxygen, conductivity, and turbidity) were monitored before and after the induced
breeding. Hatchability was assessed after 24 hours of incubation. The results showed that eggs
incubated in municipal water and borehole water recorded 63.79 and 30.31 % hatchability,
respectively. The survival percentage was 55.37 for municipal water (NMW), 40.23 for Kainji
Lake water (KLW) and 21.25 for Borehole water (NBW).
