Abstract

This research was conducted to evaluate the effectiveness of two different hormones injected for induced spawning of Clarias gariepinus. Three females and 6 males of Clarias gariepinus were collected from Abdulsalam Fish Farm in New Bussa, Kainji, Niger State. The pituitary gland was extracted from four of the male brood fish, weighed so as to get a corresponding weight to that of the recipient fish. The experiment was laid in a Completely Randomized Design (CRD) with three treatmentsT1= 100%ovulin/ (0.5ml/kg), T2 = 100% Pituitary Gland Extract/ (PGE 2mLkg) and T3 = 50% ovulin +50% PGE/(0.4ml/kg). Result indicated that 100% Ovulin performed significantly better (p<0.05) in all the parameters investigated except in hatchability rate. Fertility rates of the eggs were higher in Ovulin (96.56±2.51) than in PGE treated fish especially at mixed hormone (ovulin 50%+ PGE 50%) where the percentage mean values were 95.21±3.51 and 94.82 ±4.50, respectively. The cost of hormone was highest in mixed hormone (₦1840) which subsequently affected its net profit, followed by PGE (₦1600) and least in Ovulin (₦320) which had the highest net profit. Result showed that the use of Ovulin hormone was found to be more cost effective and efficient in the induced breeding of C. gariepinus.
