| Abstract: | The resting metabolic rates of 2.085 - 6.810 kg adult Silurus meriziionalis collected from the Jialingjiang River were measured with continuous-flow respirometers from Sep. 1991 to July 1992. At 10.0, 13.3, 16.0, 21.8, 22.2 and 27.4°C, the measured values were 8.699, 21.980, 25.412, 30.563, 34.463 and 32.483 O2 mg/(kg?h) in the female, and 8.146, 19.568, 26.830, 29.426, 32.156 and 32.098 O2 mg/(kg?h) in the male, respectively. From the values, the metabolic rates at the standard conditions (20°C; Female: 4.126 kg, Male: 2.890 kg) were converted by a statistical model. The results showed two peaks on the annual curves of the resting metabolic rates in both the male and the female. The rates March to May (the spawning season) and in Sep. to Nov. (when sexual products accumulate rapidly) were higher than those in other seasons, lower in July (summer), lowest in January (winter), indicating the annual changes in the metabolism correlated with the gonad development and reproduction activities of the fish. The annual energy requirements for resting metabolism were 28.8×102 J/(kg?a) in the male and 29.5×102 J/(kg?a) in the female. It is suggested that the level of resting metabolism in the fish, a large-size piscivore, is lower than those reported in several other fish species. |
