Evaluation of Optimum Inclusion Level Azanza Garckeana Pulp on Survival of Clarias Fingerlings

Abstract

The mortality and survival rate of feeding Clarias gariepinus with optimum inclusion of Azanza garckeana was studied for 8 weeks. 150 fingerlings of the same size was stocked in fifteen plastic bowls, 30 fingerlings was stocked each in triplicate and aerated throughout the period of experiment. Fish feed of  40% crude protein at 0 % Azanza garckeana inclusion ( control D₁), 10%(D₂), 15%(D₃), 20%(D₄) and 25%(D₅) inclusions of  Azanza garckeana.The experiment  was monitored for mortality and survival rate with reference to inclusion levels. The results of the experiment showed that, the highest mortality rate observed was in the control D₁ (22). The mortality rates in the other treatments were   D₄ (15), D₂ (12), D5(11) and the lowest in D3(5). Percentage survival was highest in  D₃ (83.3), followed by  D₅ (63.3), D₂ (60), D₄ (50) and lowest in D₁ (26.6) .From the result it could be concluded that 150g(15%) inclusion level  of A. garckeana would give better survival rate in  the culture of Clarias gariepinus.
