摘　　要：April, 1996 to March, 1997 studies on the abundance and secondary production of Limnodrilus hoffmeisteri in an algae-dominated lake showed that the worm density and biomass peaked in December at 152 ind/m 2 and 0.087 g/m 2, respectively. The secondary production of the animal was 0.294 g/m 2 fresh wt/a. The turnover rate (P/B ratio) was 11.4.April, 1996 to March, 1997 studies on the abundance and secondary production of Limnodrilus hoffmeisteri in an algae-dominated lake showed that the worm density and biomass peaked in December at 152 ind/m 2 and 0.087 g/m 2, respectively.
