陆基圆桶养殖大口黑鲈经济效益分析

Economic benefit analysis of Micropterus salmoides cultivation in land-based drum

陆基圆桶循环水养殖是一种新型高效的水产养殖模式,本研究旨在通过分析陆基圆桶循环水养殖大口黑鲈的经济效益,为促进该养殖模式的进一步推广应用提供参考。本文调查了安徽省3个县区的陆基圆桶大口黑鲈养殖企业,并对其大口黑鲈养殖的投入、产量、产值和经济效益进行分析。结果表明,投饲成本是养殖成本的第一大投入要素;通过成本与收益比较分析,投放密度、苗种来源、固定资产投入和销售时间均是影响养殖经济效益的重要因素。生产上建议养殖企业开展养殖技术研发,调整养殖模式,充分发挥陆基圆桶养殖潜力,适当延长养殖周期,提高商品鱼规格,错开销售高峰期等方式,以获得更高的经济效益。

Land-based drum recirculation aquaculture is a new and efficient aquaculture model.The purpose of this study is to analyze the economic benefits of Micropterus salmoides cultivation in land-based drum,and to provide a reference for further popularization and application of this aquaculture model.This paper investigated a total of three land-based drum farms of M.salmoide in Anhui Province,and analyzed their inputs,yields,production values,and economic benefits of M.salmoides bass aquaculture.The results showed that feeding cost was the first major input element of the culture cost.The cost and yield analysis revealed that the placement density,seedling source,fixed asset investment,and marketing time were all important factors affecting the economic benefits.In terms of production,it was recommended that enterprises carry out research and development of aquaculture technology,adjust the aquaculture mode,give full play to the potential of drum aquaculture,appropriately extend the aquaculture cycle,improve the specification of commercial fish,and stagger the peak period of sales,with a view to obtaining higher economic benefits.
