Comparative study of testis histology and haematology of Clarias gariepinus exposed to phytochemicals of Moringa oleifera and Carica papaya leaf powder

Abstract

This work was carried out to know the responses of Clarias gariepinus broodfish testis and blood when exposed to varied levels (0.50, 1.00, 1.50 and 2.00g/l) of Moringa oleifera and Carica papaya leaves powder for 8 weeks in a renewable bioassay. Results showed that temperature, nitrite and pH were within the same range with no significant difference (P>0.05). There was significance difference (P0.05). Moringa had the highest value in RBC and Hb, while C. papaya had the highest value in WBC. Analysis on the Gonadosomatic index showed significance difference (P0.05). There was no significance difference (P>0.05) in the condition factor but the values indicate a favourable condition for the fish as it was greater than 2. Histological analysis had no difference in testicular structure between the treatments as compared with the control.
