Abstract: Different hormones for facilitating egg hatchability in Katsina state of Nigeria need to be compared and evaluated in order to bring out the most economic and efficient to be used by Nigerian fish farmers with which to facilitate fish production. Due to above reason, the study on comparative analysis of ovaprim (artificial hormone) and African Catfish pituitary extract (ACPE) natural hormone in facilitating egg hatchability was focused to compare the two hormones in terms of their efficiency. Six pairs of broodstock (catfish) with three pairs each for ovaprim and ACPE were selected. The females were subjected to different treatment with ovaprim (0.5ml/kg) and pituitary gland extracts (1ml/kg ACPE hormones). The data obtained was analyzed and, the result has shown that the artificial hormone has more advantages over the natural hormone. Were hatchability rate was (90.5%) as compared to (66.0%) in natural hormones, cost was ₦25, 000 and ₦20,000, mortality rate (9.5%) and (35%) for artificial and natural hormone respectively. Therefore, artificial hormone has more advantages over natural hormone and hence recommended for use by our Nigerian fish farmers.
