This paper describes the oxygen consumption rate and the suffocation point of the mandarin fish Siniperca chuatsi and the possibility of cultivating this fish with prey species in the same pond. The oxygen consumption is positively related to the body weight (r = 0.99) of the fish. But the oxygen consumption rate is negatively related to its body weight (r = -0.97), which is about 0.14 mg/g.h. for fingerlings and about 0.12 mg/g.h. for commercial fish at 20 degree C. However, quantity and rate of oxygen consumption are both positively related to water temperature (r = 0.90, r = 0.94 respectively), when water temperatures ranged between 13 and 30 degree C and the body weight is 230 +- 11.7 g, the quantity of oxygen consumption varied from 14.31 to 42.13 mg/individual.h. and the rate of oxygen consumption 0.059-0.175 mg/g.h. The daily variation pattern of the oxygen consumption rate of the mandarin fish is contrary to other cultivated fish in China, with peak consumption being 0.12-0.15 mg/g.h. at night and valley consumption 0.07-0.10 mg/g.h. during the day. The suffocation point of the mandarin fish is 0.45-0.76 mg/L, which is similar to many other cultivated fish. The cultivation of mandarin fish with prey fish in the same pond can not only provide constantly plenty of suitable foods for mandarin fish, but also serves as a simple and easy practice for the high benefits of mandarin fish cultivation.
