温度与盐度对云龙石斑鱼幼鱼耗氧率和排氨率的影响
Effects of temperature and salinity on oxygen consumption rate and ammonia excretion rate of junevile Epinephelus groupers
摘要
Abstract
In order to study the effects of temperature (24,27,30 and 33℃) and salinity (15,20,25,30 and 33) on oxygen consumption rate (OCR) and ammonia excretion rate (AER) of juvenile Epinephelus groupers in repletion and hunger,the OCR and AER were examined with the method of closed flow respiration experiment.The results showed that both in repletion and hunger,the OCR and AER of juvenile Epinephelus groupers were affected by temperature and salinity significantly (P＜0.05);when the temperature was 24℃-33℃,the OCR and AER in repletion were respectively 30.29％-131.84％ and 131.82％-316.19％ more than in hunger.In repletion,O ∶ N,Protein-supplying ratio (PSR),Q10(respiration) and Q10(excretion) were 12.54-20.18,27.74％-48.48％,1.21 and 1.60 respectively,and in hunger,25.77-35.90,19.49％-27.19％,1.87 and 3.41 respectively;when the salinity was 15-33,the OCR and AER in repletion were respectively 100.41％-128.21％ and 182.19％-382.83％ more than in hunger.In repletion,O ∶ N and PSR were 13.32-20.72 and 39.47％-49.42％ respectively,and in hunger,29.18-30.98 and 22.59％-23.98％respectively.The study showed that the optimum growth temperature of juvenile Epinephelus groupers was 24℃-27℃,and the optimum growth salinity was 30-33.关键词
