Reaction of himri (Barbus luteus), to carp pituitary extract injections tested month and a half before its natural spawning. Females treated with two consecutive injections resulted higher relative fecundity (7464.96 ± 481 eggs) than those treated with only one injection (5286.62 ± 392.5 eggs). No significant differences noticed between treated (22.5 ± 0.4 ml) and non-treated males (23.2 ± 1.6 ml). High fertilization (98.6-97.8 %) could not attain satisfactory hatching (57 %). Colors modifications and acoustic acts have been observed during ripping. Spawned egg has 1.57±0.3x $10^{-3}$ g weight and 1.10-1.18 mm diameter. Spermatozoon motility increased significantly (45%) in hypotonic solution (150 mOsm. $kg^{-1}$). Embryonic development was similar to other cyprinids in durations, but the important stage of eye pigmentation has not been noticed even after hatching which occurred after about 74 h.
