本文根据1988—1990年对吉林省镇赉渔场养鱼池的生态学调查材料,论述了鱼池生态系统的非生物环境、生物群落、初级和次级生产量、有机碳的平衡、能流和生物能量收支。一年约有28.3—51.4％收入有机碳沉积池底。各池鱼产量约为总收入能量的4.7—10.2％;鲢鳙产量约为浮游植物毛产量的5.1—13.7％;鲤产量约为人工饲料能量的6.5—13.1％。浮游植物和细菌的能量有55.2—81.4％为浮游动物所利用,18.4—22.4％为鲢鳙所利用,仅0.2％为底栖动物所利用。
Based on the ecological survey data of fish ponds in Zhenlai Fisheries Farm, Jilin Province from 1988 to 1990, the paper discussed the abiotic environment, biome, primary and secondary production, balance of organic carbon, energy flux and bioenergy Income and expenditure. About 28.3-51.4% of organic carbon sinks are collected in the year. The production of each pond is about 4.7-10.2% of the total income energy; silver carp and bighead carp production is about 5.1-13.7% of the gross production of phytoplankton; and the production of carp is about 6.5-13.1% of the energy of artificial diet. Phytoplankton and bacteria have 55.2-81.4% of the energy used by zooplankton, 18.4-22.4% of the silver carp and bighead carp, and only 0.2% of them are used by zoobenthos.
