Summary: The effect of pH, salinity, total ammonia-N and alkalinity on oxygen consumption rate (OCR) were studied in embryos and larvae of the Chinese Sturgeon (Acipenser sinensis) with closed volumetric flasks. The OCR of embryos increased with pH values rising from 5.5 to 7.0, but decreased with higher pH values rising from 7.0 to 9.0.The optimum pH as a single variable was determined to be between 6.5 and 7.5.OCR of embryos and larvae increased as the water salinity increased from 1.25to 20, but it became stable when salinity was higher than 40In water containing 1.07 mg/L to 34.15 mg/L of total ammonia-N both respiration frequency and OCR increased with the increase of concentration of total ammonia-N, but decreased when concentration was higher than 34.15mg/L.OCR of larvae increased with alkalinity.
