Yisa, T.A. | Awoku, D.T.
This paper reviewed the effect of synthetic and non-synthetic hormones on the fecundity fertilization, hatching, latency period and ovulation of Clarias gariepinus. The reviewed result confirmed the necessity of stimulating fecundity in Clarias gariepinus with hormones complexes. The effectiveness of synthetic hormones over the non-synthetic hormones in fecundity stimulation and the highest fecundity level, hatching and fertilization recorded was from the synthetic hormonal sources. Hormonal substances influenced greatly fecundity, ovulation, fertilization of Clarias gariepinus but the technical- know- how involved in getting the non-synthetic hormone such as pituitary is very difficult and rigorous which makes the synthetic counterpart preferable.
