| 摘 要： | The energy flow of Branchiura sowerbyi was studied for the first time in China in a shallow macrophytic lake, Biandantang Lake, Hubei Province. The energy flow was calculated from the measurement of flesh production (12.5241kJ/m^2a), egestion (517.7302kJ/m^2a), metabolism (38.3273 kJ/m^2a), and excretion (4.3798kJ/m^2a). The net growth efficiency of the species is about 22.7%, which accords well with the generally reported value for oligochaetes. In addition, the relationship between starvation respiration (R, mgO2/ind‘d), wet weight (Ww, mg) and temperature (T, ℃) were also measured, with the regression function being R=0.008 Ww^0.736 e^0.050T.
