A comparative Assessment of ova prim and ova tide on the Breeding performance of catfish (Clarias gariepinus).

Abstract

The effect of ovaprim and ovatide on the breeding performance of catfish (Clarias gariepinus) in Benue state, Makurdi, Nigeria was investigated from the month of July to August, 2016. The female brood stocks weighed 1.0-1.2kg and the males weighed 1.2-1.5kg.Twelve (12) female and six (6) male brooders were obtained from Ocepson’s farm and Aqua-heaven fish farms respectively in Makurdi. The doses of 0.8ml/kg, 0.5ml/kg and 0.3ml/kg of ovaprim and 0.3ml/kg, 0.2ml/kg and 0.1ml/kg of ovatide were used to determine the dosage that would give the best output in fecundity, fertility and hatchability in the fish. The females treated with 0.8ml/kg of ovaprim had the highest fecundity of 92, 600 eggs and this was significantly different (p<0.05) when compared with doses of 0.5ml/kg and 0.3ml/kg. The females treated with 0.1ml/kg of ovatide had the highest fecundity of 89, 100 eggs but there was no significant difference (p>0.05) with 0.2ml/kg and 0.3ml/kg. The fertilization rate of 84.47% was the highest at 0.8ml/kg in ovaprim and showed no significant difference (p>0.05) with the other doses. In ovatide, fertilization of 81.82% was the highest at 0.1ml/kg and it showed a significant difference (p<0.05) when compared with the rest of the doses. The highest hatchability rate of 62.45% was observed in ovaprim at 0.1ml/kg and showed no significant difference (p>0.05) between 0.5ml/kg but showed a significant difference (p<0.05) in 0.3ml/kg. In ovatide, hatchability of 70.21% was the highest at 0.1ml/kg and showed significant difference (p<0.05) when compared with the rest of the doses. Ovaprim hormone at the dosage of 0.8ml/kg and ovatide hormone at the dosage of 0.1ml/kg gave the best result in Makurdi, Nigeria.
