The fecundity of four batch weights (10 samples each) o gravid Clarias gariepinus weighing 60 ± 0.17159 g 125 ± 0.15092 g 250 ±0.20683 g and 500 ± 0.15670 g raised from the hatchery was investigated The paired ovary of each fish was dissected out, weighed (g) and its length measured (mm). Each paired ovary was stored n a solution of 1 % formalin in 0 6 % saline solut on for at least 3 weeks for the solution to harden the eggs and remove egg clumping. After 3 weeks, each paired ovary was torn apart on a 2 mm mesh circular fabricated sieve over a stream of water. The eggs passed through the 2 mm mesh sieve into a receptacle. Sub sample of the eggs from each paired ovary was taken, counted and all the eggs in each paired ovary were determined thereafter by volumetric method. The tota fecund y of 40 gravid f sh stud ed ranged rom 6,450 to 71,450 eggs per f sh. The mean fecundities of the 60 g 125 g, 250 g and 500 g f sh were 8,501.9 ± 295.5, 13,364.0 ± 1734.3, 41 087.9 ± 12258.1 and 51,186.0 ± 13851.0 eggs respect vely. The relationships between fecundity and fish weight (FW) (n = 40, r = 0.8761), f sh ota leng h (TL) (n= 40, r = 0.8266), f sh ovarian we ght (OW) (n = 40, r = 0.7609), fish ovar an length (OL) (n = 40, r = 0.7236), gonadosomatic index (GSI) (n = 40, r = 0.5992) and f sh cond t on factor (K) (n = 40, r = 0.9046) obta ned were linear and positive and the condit on factor appeared to be the best predictor of fecundity in C. gariepinus studied. The higher fecundity o C. gariepinus (range: 6,450 to 71 450) obta ned from th s study when compared w th the range of 9,000 to 25,000 earlier reported from the wild stock indicates that hatchery-raised C. gariepinus is more fecund than the wild fish in the Anambra area of the sub-region. Therefore, hatchery-raised C. gariepinus appears to be better for fish breeding in fingerl ngs production than the wild fish.
