Net present value and price as two methods can be used for evaluation of natural resources depreciation. In this paper, an approach based on the net present value is used to consider the changes in the value of fisheries resources. Changes in the value of fisheries resources come from the annually changes in catch. These changes must be considered in the national accounting system to arrive at sustainable income. The sustainable income is maximum value that a person consumes during a time period so that the well - being level of end fishing effort. Econometric calculations by OLS (ordinary least squares) are showed that over most years, the fisheries resources depreciated and this trend is with increasing the effort, Therefore, the policies reducing the fishing effort are recommended. Then Labor surplus must be driven to other sectors.
