Abstract:The oxygen consumption rate of R. philipppinarum was studied under different tempera-tures and abrupt change in laboratory by means of ecological methods. 5 constant temperatures (15 ℃, 20 ℃, 25 ℃, 30 ℃ and 35 ℃) and 4 abrupt changes(changing from 25 ℃ to 15 ℃, 20 ℃, 30 ℃ and 35 ℃, respectively) were set. The results showed that temperature had significant ef-fects on the oxygen consumption, the oxygen consumption increased with the increase of water tem-perature from 15 ℃ to 30 ℃ and reached to the maximum at 30 ℃. However, when the water tempera-ture was higher than 30 ℃, oxygen consumption rate of R. philipppinarum decreased. As a whole, the highest and the lowest of oxygen consumption rate appeared at 30 ℃ and 15 ℃, respectively. The differences among 15 ℃, 20 ℃, 35 ℃ were not significant(P>0.05), and among 25 ℃, 30 ℃, 35 ℃ were not significant(P>0.05), however, the oxygen consumption rate of 25 ℃ and 30 ℃ were significantly higher than 15℃ and 20 ℃(P<0.05). The oxygen consumption rates of R. philipppina-rum after temperature change were all higher than the same constant temperatures, suggesting that more energy would be used when subjected to abrupt temperature change.
