Abstract Barbus bynni begins to mature at Age IV. Ripening of gonads of mature fish starts in May when water temperature approaches the annual maximum. However, the spawning season coincides with the onset of the flood season in July. These facts, as well as the cyclic growth of the gonads, show that B. bynni spawns once a year. Fecundity varies with size of fish and gonads. However, this levels off in the middle size group. At this age the fecundity was estimated to be 1 424 693 eggs.
