| description | Ten gravid Clarias batrachus females were administered with a single dose of common carp pituitary
homogenate (CPR). Bifore injection, the eggs were light yellow and the diameter rangedfrom 0.94 mm to
1.08 mm. Ovulation occurred approximately 12 hours after the adminstration of CPR. The colour of the
eggs turned brown and the diameter rangedfrom o. 99 mm to 1.27 mm. The fertilization rates rangedfrom
10-81%. The eggs hatched after about 30-36 hours of incubation at 26°C to 28°C. The hatching
rates ranged from 13-67070. |
