Ten gravid Clarias batrachus females were administered with a single dose of common carp pituitary homogenate (CPH). Before injection the eggs were light yellow and the diameter ranged from 0.94 mm to 1.08 mm. Ovulation occurred approximately 12 hours after the administration of CPH. The colour of the eggs turned brown and the diameter ranged from 0.99 mm to 1.27 mm. The fertilization rates ranged from 10-81 . The eggs hatched after about 30-36 hours of incubation at 26 degrees C to 28 degrees C. The hatching rates ranged from 13-67
