Abstract

The study aims to assess productivity, economics, energy use efficiency and CO2e emissionfrom integrated fish-duck farming system (IFDF system) in floodplains of the eastern India.A total of six fish ponds were constructed and developed as IFDF system under floodplainsin which fingerlings were stocked @4000 acre-1 and integrated with 150 numbers of KhakiCampbell ducks. Average growth rate of fishes ranged from 27 g month-1 of mrigal to 31.7 gmonth-1 of grass carp and average body weight ranged from 465.2 g of mrigal to 823.2 gof grass carp. The fish equivalent yield was obtained as 3.06 t acre-1 year-1. The total energyinput, output and energy use efficiency ratio estimated were 111.8 GJ and 21.2 GJ and 0.19,respectively. Net income earned was ₹234393 acre-1 year-1 and BC ratio estimated was 1.91.Further, 0.56 kg CO2e was emitted to produce 1.0 kg of fish equivalent, which was muchlower than that of the production of rice, mutton and milk. Keywords:CO2e emission, Economics, Energy, Fish-duckfarming, Floodplain, Productivity

印度东部洪泛湿地生态系统鱼鸭综合养殖的生产力、能源利用效率、经济性和二氧化碳排放量

该研究旨在评估印度东部洪泛平原鱼鸭综合养殖系统（IFDF 系统）的生产率、经济效益、能源利用效率和二氧化碳排放量。在洪泛平原共建造和开发了 6 个鱼塘作为 IFDF 系统，其中按 4000 英亩-1 的比例投放鱼苗，并与 150 只卡其-坎贝尔鸭相结合。鱼类的平均生长率从胭脂鱼的 27 克/月-1 到草鱼的 31.7 克/月-1 不等，平均体重从胭脂鱼的 465.2 克到草鱼的 823.2 克不等。鱼当量产量为 3.06 吨/英亩-年-1。估计的总能源投入、产出和能源利用效率分别为 111.8 千兆焦、21.2 千兆焦和 0.19。此外，生产 1.0 千克鱼当量需排放 0.56 千克 CO2e，远低于大米、羊肉和牛奶的产量。关键词：CO2e 排放经济学能源养殖鱼鸭洪泛区生产率
