摘要
中国花鲈养殖是我国沿海重要的海水鱼养殖产业之一,对该行业进行全面、客观的评价有利于促进该产业自身的可持续发展。根据实地调研数据评估了不同养殖模式下花鲈养殖的经济效益。结果表明:在经济效益方面,池塘养殖模式下花鲈单位产量总成本最低。其中池塘养殖模式下为16.69元/kg,普通网箱养殖模式下为31.48元/kg,深水网箱养殖模式下为36.62元/kg。在成本结构方面,可变成本所占比例均高于固定成本,其中饲料成本占比最大,其余成本项目根据养殖模式而产生差异。在盈亏平衡分析与敏感性分析中,池塘养殖易受市场波动影响,普通网箱养殖具有一定的规避市场风险的能力。基于此,建议池塘养殖主产区加强产业集群程度,延伸产业链。网箱养殖户应提高科学养殖技术水平,减少对环境的污染。管理部门应通过对花鲈苗种质量和养殖环境的有效监管为养殖生产者提高经济效益提供更好的制度环境。
Chinese sea perch（Lateolabrax maculatus） is an important farmed species in the coastal area of China. In order to promote the sustainable development of its production sector,this study evaluated the economic efficiency of the sea perch farms located in Zhuhai and Fuding city. The research result revealed that the total unit cost of pond aquaculture farms is the lowest,which is 15. 69 yuan/kg. As for the cage farms,the cost range is 31. 48 yuan/kg-36. 62 yuan/kg. And the cost structure of the above modes had one similarity： the proportion of the variable cost is higher than that of the fixed cost. Because feed cost is the most expensive expenditure for sea perch farming industry. What ＇s more,the break-even and sensitivity analysis stated that the economic performance of the traditional cage farms is the best. Combined with the actual situation,the recommendations are as follows： The value chain of the fish in Zhuhai should be extended; The fish farmers who practiced in cages should adopt advanced technologies to increase the economic efficiency and reduce the pollution; Related departments should inspect the quality of the aquatic fingering industry and the pollution of the production.
