Abstract:

Tilapia have gotten a lot of attention because of their favorable features, which make them an excellent Aquaculture choice. This trait comprises the ability to replicate easily in captivity and a short generationtime; quick growth, reaching consumable size (in about six months) and the ability to survive a wide range of environmental conditions; tolerance to disease and stress; flexible food environments;use of artificial feed immediately after yolksac absorption; adaptable to a variety of culture methods; palatable,marketable,and nutritious goods. This study investigated the control of prolific spawning in Oreochromis niloticus using C. papaya seed extract by evaluating its effect on its gonads as a sterility inducing agent in the control of excessive spawning as well as to establish the phytochemicals present in C. papaya seed. It also evaluated the growth performance and survival rate of Oreochromis niloticus fed with C. papaya seed extract for 31 days. Five different treatments T1, T2, T3, T4, and control with different inclusion levels of C. papaya seed extract and a total of 500 Oreochromis niloticus fry were used for the study. The study indicated that growth performance of Oreochromis niloticus fed with seed extract is not significantly different when varied at different concentration of 100, 75, 50, 25, 0ml. A gradual decrease in the survival rate of Oreochromis niloticus was observed as the concentration of the C. papaya seed extract was increased. From the study, the control group has the best growth performance and high survival rate, while the gradual deformation of the fishes’ gonads was observed with increase in the concentration of the extract in feed when fed for 31 days and adversely affected their survival rate; further study should be carried out using other plant extract.
