Effects of Salinity and Body Weight on the Oxygen Consumption and Ammonia Excretion Rates of Paphia undulate
摘要
Abstract
By using experimental ecological method, the effects of temperature and body weight on metabolism of Sipunculus nudus were compared. The S .nudus animals were divided large (L), middle (M) and small (S) size groups, there were significant difference among the groups (p < 0.05). The temperatures set were 10℃, 15℃, 20℃, 25℃ and 30℃.The results showed that oxygen consumption rates increased with the rise of temperature ranging from 15℃ to 25℃. When the temperature reached to 30℃, the small group oxygen consumption rates continuously increased, but the big and middle oxygen consumption rates decreased. At each temperature set, the small group had the largest oxygen consumption, followed by the middle and big groups. There were no significant difference in oxygen consumption among the three groups at 10℃ (p > 0.05 ) , but significant difference were observed at 15℃, 20℃, 25℃ and 30℃ ( p < 0.05). Ammonia excretion rates increased when the temperatures varied from 10℃ to 25℃. At the same temperature set but 10℃, the small group had the largest ammonia excretion rate, followed by the middle and big groups. There were no significant difference in ammonia excretion rate among the three groups at 10℃ (p > 0.05 ) , but significant difference were detected at 15℃, 20℃, 25℃ and 30℃ (p < 0.05). The results showed that both temperature, body weight and the interacting effects of temperature and body weight were significant on oxygen consumption and ammonia excretion rate (p < 0.05).关键词
