Amblypharyngodon mola was found to breed thrice a year during the spawning months of July, August, October and March in the Kaptai Reservoir. GSI (Gonadosomatic Index), GLI (Gonadal Length Index) and Ova Diameter (OD) frequency showed three peaks in a year during the breeding months, which confirmed the multiple breeding nature of the fish in Kaptai reservoir. Female dominated significantly over male throughout the year and overall sex ratio of male and female was 1.00:2.078 (χ2 =202.48, p<0.01, N=1650, d.f. 1). Fecundity varied from 1,280 (for a fish of total length 47.5 mm, body weight 1200 mg and ovary weight 90 mg) to 13,679 (for a fish of total length 87.5 mm, body weight 10,528.57 mg and ovary weight 1668.71 mg) with an average 5,182.67±3, 731.51 eggs (n=120). Fecundity factor (995 eggs g-1 of body weight) indicated that the fish was highly fecund. Fecundity was highly correlated (p<0.01) with body length, ovary weight and ovary length.
