Abstract
Effects of oven and air-dried pituitary hormone on the ovulative capacity of gravid Clarias gariepinus was carried out in a commercial fish hatchery farm between the months of October and November, 2008. Nine female gravid Clarias gariepinus weighing about 1kg each was injected with oven dried, air dried and wet pituitary hormone (wet pituitary hormone acted as the control). Injected brooders underwent indoor temperature conditions varied from 240C -270C, ovulated eggs were manually expressed and incubated. Differences occurred among the means of the treatment with respect to weight of the egg per treatment and rate of hatchability among the samples. There is no significant difference between oven dried pituitary (Treatment 2) and (Treatment 1) which is the control except in the number of eggs. The mean difference percentage hatching and weight of ovulated egg is significant at (p < 0.05).
