1 Department of Animal Husbandry- Agriculture Faculty in Deir ez Zor, Aleppo University, Syria Viewed : 1182 - Downloaded : 899 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±0.3×10-3 g weight and 1.10-1.18 mm diameter. Spermatozoon motility increased significantly (45%) in hypotonic solution (150 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.
