Studies were conducted to determine the effects of water temperature on the number of spawning, egg production, spawning intervals and hatching success of Chinese bleak, Aphyocypris chinensis. Adult fish were exposed to water temperatures of 19, 22, 25 and $28{circ}^C$ for two months in the laboratory. The spawning number, egg productivity, and hatching rate increased as water temperature increased between $19{circ}^C$ and $25{circ}^C$. Maximum egg production and hatching rate occurred at $25{circ}^C$, whereas the spawning intervals decreased as water temperature increased except for the treatment of $28{circ}^C$. The shortest spawning interval observed at $25{circ}^C$.
