北京市不同养殖类型鲟鱼养殖成本收益分析

论文以北京市鲟鱼不同养殖模式成本收益变化为研究对象，从微观角度，采用统计分析方法，对北京市育苗类型、成品鱼型以及混合型三种类型的鲟鱼养殖模式的成本收益进行分析，结合产品流通不同形式，对北京市不同类型鲟鱼养殖成本收益进行对比，结果显示：混合型养殖成品鱼成本收益最高，成品鱼成本收益达到0．2915；其次是自育苗一一成品鱼模式，成本收益为O．2679，最低的是购买鱼苗一一成品鱼型，成本收益为0．2317；对于鱼苗成本，混合型物质成本均高于其他两种养殖类型，比较之下，由于规模和专业化程度的提高，育苗型企业鱼苗成本最低。育苗企业和混合型养殖企业鱼苗的成本收益平均为1．5175和0．9633，从销售渠道对收益影响分析，由于农家乐增加了相关服务或加工成本，农家乐成品鱼获利水平最高，最低的是商贩上门收购渠道。因此，加强养殖技术辅导，提高养殖成活率和养殖效率，拓展销售渠道成为提高北京市鲟鱼养殖收益的重要渠道。

The analysis cost benefit of different breeding sturgeon aquaculture in Beijing

This paper takes the cost benefit change of sturgeon different cultivation mode in Beijing as the object, From the Angle of the micro, analysis the cost benefit of Seedling type and mixed type, finished product fish in Beijing, Combining the circulation forms of product, comparing the cost and benefit of the different types of sturgeon fanning in Beijing. The highest revenue cost of the finished fish is Mixed farming model, the cost of revenue reached 0.2915; Followed from the nursery - finished fish pattern, the cost of revenue reached 0.2679, Lowest purchase fry - finished fish pattern, the cost of revenue reached 0.2317; For fish cost, the cost of hybrid material were higher than the other two types, by contrast, because of the increase in size and the degree of specialization, The lowest cost of seedling enterprises fish fry. the cost of revenue Nursery enterprise and hybrid breeding fish fanning enterprises are 1.5175 and 0.9633 respectively. From the impact of sales channels, the highest profit of rural tourism due to the related service or processing cost, the lowest door-to-door purchase channels, so strengthen the breeding technology guidance, enhancing the survival rate of breeding and breeding efficiency and expand sales channels become the important channel to improve the income of sturgeon fanning.
