This paper studied the tolerance of Craspedacusta sowerbyi xinyangensis to the stresses of temperature, salinity, and pH from the aspects of its living status, morphology and survival, and measured its oxygen consumption rate and oxygen tolerance at different temperatures. The results indicated that the suitable temperature and pH of C. sowerbyi xinyangensis were 15 degrees C - 25 degrees C and 6.0 - 8.2, respectively. C. sowerbyi xinyangensi had a low tolerance to salinity, and it could only survive for 96 h when the salinity was 2. C. sowerbyi xinyangensi could bear low DO, and its lethal DO was 0.26 mg x L(-1) at 20 degrees C. The average oxygen consumption amount and rate of C. sowerbyi xinyangensi increased with increasing temperature.
