Energy Flow of Macrozoobenthos Community in an Algal Lake, Houhu Lake(Wuhan, China)
摘要
Abstract
Energy flow of the macrozoobenthic community in an algal lake, Houhu Lake ( Wuhah, China) was investigated from April, 1996 to March, 1997. The estimated consumption of the community was 2522.7 k J/( m2· a); defecation was 2049.1 k J/( m2 · a); metabolism 371.2 k J/( m2 · a); excretion 34.7 kJ/(m2· a) and production 67.7 kJ/(m2.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.关键词
