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