Research Situation and Prospect of Biogas Slurry Utilization in Fish Culture

畜禽粪污发酵所产生沼液的处理与综合利用问题已引起学者的广泛关注。综合介绍了国内外利用沼液养鱼的研究现状及发展趋势。主要从沼液的有效成分、沼液促进鱼的生长机制、沼液养鱼技术及效益、沼液养鱼潜在的环境影响和风险等方面进行了评述,并在此基础上提出了今后的研究方向。

Treatment and comprehensive utilization of biogas slurry generated by animal manure fermentation have attracted wide attention of scholars. This paper introduced the present situation and development prospect of research on biogas slurry utilization in fish culture. The research status was reviewed from several aspects ： active constituents in biogas slurry, mechanism of fish growth promoted by biogas slurry, fish-farming technique and benefit by using biogas slurry, potential environmental impact and risk from the biogas slurry utilization. Based on those, research directions in the future were proposed.
