Abstract: According to the monthly investigations conducted in Guanghaiwan Bay, Taishan City (21°52′～21°56′N, 112°46′～112°53′E) from 2013 to 2015, the occurrence and variation of the eggs of Stolephorus commersonii, with water temperature and salinity, were investigated and relations between the egg occurring time and water temperature were analyzed. It showed that the spawning season of Stolephorus commersonii started around March each year, but ended in months from September to November. The eggs of Stolephorus commersonii discontinuously occurred by batch in a year, which normally had 2 to 4 batches in total. The quantity of the first batch was the highest and it peaked around April. During this period, the water temperature ranged from 19.8 to 31.3℃, whereas the rage of salinity varied widely from 7.66 to 33.65. It showed that the eggs preferred to occur in water of higher temperature and low salinity. The lowest water temperature for the spawning of Stolephorus commersonii should be around 20℃. In the early spawning period when water temperature reached, the eggs of Stolephorus commersonii firstly occurred. By comparing the waters in different latitudes, the higher the latitude is, the later the eggs of Stolephorus commersonii appear.
