The estimated consumption of the community was 2522.7 kJ/(m 2·a); defecation was 2049.1 kJ/(m 2·a); metabolism 371.2 kJ/(m 2·a); excretion 34.7 kJ/(m 2·a) and production 67.7 kJ/(m 2·a). The assimilation rate of the community was 19%; and 81% of its ingestion was defecated. The computed net growth efficiency was 14%, much lower than most reported values, which meant that the macrozoobenthic community in Houhu Lake utilized food less effectively.展开更多
