The artificial propagation technologies of Sillago sihama from natural brood stock were studied. The results showed:under the temperature of sea water 27.5-31.5 , salinity 18℃ -31, and pH 8.0-8.5, the fish spawned by accelerate ripening cultivate. A total of 10 batches got fertilized eggs 67×104, and about 42.6×104 larvae were hatched. The fertilizing rate was 37.2% - 89.3%, and the hatchability was 24.8%-97.6%. Under the temperature of sea water 29-30 , salinity 28,℃ and pH 8.4, it required 14 h 40 min for the Sillago sihama embryonic development. 2.8×104 young fish with average total length 35 mm were cultivated through 35 days rearing, and the survival rate was 24.6%.
