深远海大型养殖工船金鲳鱼卷积生产养殖模式经济可行性论证

Economic Feasibility Demonstration of Golden Pomfret Convolution Aquaculture Mode with a Large-scale Aquaculture Vessel

本文以项目团队创新设计的12万方深远海大型养殖工船为经济性可行性研究对象。根据养殖工船以及金鲳鱼(卵形鲳鲹)养殖的特点,提出一种陆海接力、分级养殖、工业化卷积生产模式。通过全年连续稳定高效率的金鲳鱼养殖生产,实现经济效益的成倍提高。基于成本效益分析方法,建立成鱼收购价格与项目投资回收期、成本利润率等核心经济指标的关联模型。当金鲳鱼养殖密度为25kg/m^(3)、存活率为90%的情况下,通过经济模型分析得到以下结论:金鲳鱼盈亏平衡价格为23.8元/kg,满足项目设定经济指标(成本利润率>17%,投资回收期<7年)的边界价格为29.9元/kg。对比金鲳鱼历史成鱼收购价格行情,在12万方养殖工船上采用卷积式生产模式养殖金鲳鱼经济上可行。

The economic feasibility study object of this paper is the 120000 square meters of large-scale breeding factory ship in the Far East Sea innovatively designed by the project team.According to the characteristics of breeding factory ship and golden pomfret(Trachinotus ovatus scad),a land sea relay,graded breeding and industrial convolution production mode was proposed.Through continuous stable and efficient production of golden pomfret throughout the year,the economic benefits have been doubled.Based on the cost-benefit analysis method,establish a correlation model between the purchase price of adult fish and core economic indicators such as project investment payback period and cost-profit margin.When the breeding density of golden pomfret is 25kg/m^(3) and the survival rate is 90%,the conclusion obtained through economic model analysis is that the breakeven price of golden pomfret is 23.8 yuan/kg,and the boundary price that meets the economic indicators set by the project(cost profit margin>17%,investment payback period<7 years)is 29.9 yuan/kg.Compared with the historical purchase price of golden pomfret,it is economically feasible to adopt the convolutional production mode to breed golden pomfret on a 120000m^(3) breeding factory ship.
