NFRDI implements the National Stock Assessment Program (NSAP) for cross-cutting stages of production, which provides scientific baseline data on optimal utilization of aquatic resources and fish stocks. This information is used to develop guidelines for establishing harvest control rules for different species.

The program incorporates an ecosystem approach to fisheries management (EAFM) and responsible fishing, taking into account the human dimension of society and promoting balanced and sustainable use of resources.

NSAP collects data from 742 landing sites and performs time-series analysis of stock status per fishing ground, to support the strengthening of the 12 Fishery Management Areas across the country.
