摘要

本研究旨在衡量迪亚拉省鱼塘和浮式网箱养鱼场项目的风险程度,采用盈亏平衡分析方法衡量生产风险和价格风险,采用投资回报率差异系数准则衡量投资风险,选择迪亚拉省作为应用模型,采用随机抽样法收集现场数据。根据为此目的准备的问卷调查表,其中包括该省全部养鱼场项目的30%,因为样本包括土池鱼塘项目总数的28%和浮笼鱼塘项目总数的31.5%。为保证测量风险的准确性,将鱼塘和浮式网箱的养鱼场项目按生产能力的大小分为小生产能力和大生产能力两类,在研究研究样本项目的风险标准的基础上,采用研究项目投资回报率的差异系数判据得出研究样本项目的风险标准。与土塘相比,浮网箱的生产风险、价格风险和投资风险程度较高,因为浮网箱的经济效益高于鱼塘。至于两种养殖项目按生产能力大小的风险程度,根据上述标准可以看出,两种养殖场(鱼塘、浮式网箱)的风险生产率和价格程度随生产能力的小而增加,而随生产能力的大而下降。

Measuring The Degree Of Risk For Fish Farming Projects In Fish Ponds And Floating Cages In Iraq (A Case Study In Diyala Governorate (
The research aimed to measure the degree of risk for fish farms projects in fish ponds and floating cages in Diyala governorate, and adopted the method of break-even analysis to measure the productive and price risk, and use of the criterion of the difference coefficient for the return on investment to measure the investment risk, Diyala province was chosen as an application model and the field data collected according to the random sample method, which included 30% of the total fish farm projects in the governorate, as the sample included 28% of the total fish ponds projects in earthen ponds and 31.5% of the total fish ponds projects in floating cages based on a questionnaire form prepared for this purpose, and for the purposes of accuracy in measuring risk The sample was divided according to the size of production capacities into small production capacities and large production capacities for fish farms projects in fish ponds and in floating cages, and in light of studying the risk criteria for projects for the research sample, it was reached using the criterion of difference coefficient of the return on investment for the studied projects. The degree of productive, price and investment risk is high in floating cages compared to earthen ponds because they achieve higher economic returns than those achieved by fish ponds. As for the degree of risk of fish farming projects in both types of culture according to the size of production capacities, it has been shown in light of the above-mentioned criteria that the degree of risk Productivity and price increased with small production capacities, but decreased in large production capacities for both types of fish farms (fish ponds, floating cages).
