The study aims to derive the hypothetical curves for the Iso- Internal Rate of Return Curves for the investment in marine fish farming in the North Coast. In addition to the following goals: (1) Determining the most important factors affecting fish production from sea sources. (2) Estimating investment efficiency measures in marine fish farming in the northern coast. (3) Estimating and measuring the impact of the most important risks arising from changes in technical coefficients and economic variables affecting investment in fish farming by measuring their impact on the values of the studied investment efficiency measures. (4) Deriving various combinations of technical coefficients or economic variables that determine Iso-IRR Curves for marine fish farming in the studied area.
In achieving its previous objectives, the study relied on primary field data collected from a random sample of 20 marine fish farms on the northern coast. The study also relied on descriptive and quantitative statistical analysis methods. In addition to estimating the inflow, outflow and net cash flows sheets, and estimating the investment efficiency indicators.
