Influences of Temperature and Weight on Oxygen Consumption Rate and Ammonium Excretion of Oplegnathus punctatus and Their Circadian Rhythms
摘要
Abstract
Through closed water breathing experiment, we evaluated the oxygen consumption rate and ammonium excretion rate of Oplegnathus punctatus and their circadian rhythms under the effects of water temperature (20、25 and 30 ℃) and different body weights((50.94±5.50), (103.61±10.48), (154.58±7.56) and (194.56±14.56)g).The results indicated that the oxygen consumption and ammonium excretion rates of O.punctatus increased with temperature and weight but were inversely proportional to weight, The data showed that daily average oxygen consumption rate during the day was (2.535±0.204) μg·(g·min)-1 and the average oxygen consumption rate in the night was (2.531±0.064) μg·(g·min)-1.Therefore, the oxygen consumption rate of day and night is not different significantly.Moreover, we found that the average of ammonium excretion rate in the day was (0.104±0.007) μg·(g·min)-1 and the averageof ammonia excretion rate in the night was (0.083±0.007) μg·(g·min)-1, and the average of ammonium excretion rate in the daytime was obviously higher.Our further studies found a trend of gradual reduction of the oxygen consumption rate of O.punctatus after feeding with the highest appeared between 1 and 3 h and the lowest between 19 and 23 h, and ammonium excretion rate increased first and then decreased.In addition, we also found that the highest rate of ammonia excretion time advanced when the temperature increased.关键词
