National Stock Assessment Program - Interactive Atlas

NSAP Interactive Atlas is a start up web application anchored on the activities and results of NSAP created using modern web technologies to provide public information on the status of Philippine fisheries.

It provides the latest available monitored landed catch data of the country that can be used by the industry, policy makers, researchers, students, fisheforlks and other stakeholders, hence, made accessible to the public at varying degrees of access, managed by NFRDI and BFAR regional NSAP personnel.

The project developer continuously expands the system’s capability, adds more functionalities based on suggestions, and puts together innovation based on the modern standard.

HISTORY The National Stock Assessment Program (NSAP) was first conceptualized in 1995 by Mr. Noel C. Barut, who was then the chief of the Pelagic Section of the Fisheries Resources Research Division of the Bureau of Fisheries and Aquatic Resources. He is regarded as the “Father of NSAP.” With the transfer of the BFAR’s statistics function and personnel to the Bureau of Agricultural Statistics in 1988 and subsequent change in mandate, Mr. Barut saw the need for BFAR to establish its own landed catch and effort monitoring system to generate data that could be used for capture fisheries management.

Interactive Atlas would not have been possible without the support of the first members of National Stock Assessment Program.


This program aims to provide information and establish the status of the country’s fishery resources as a basis in the formulation of policies and management options for the sustainable production of marine resources.

1. To determine the catch per unit of effort, relative abundance, seasonality, and species composition of major species by gears;

2. To estimate the population parameters (i.e., growth and mortality, recruitment pattern, probabilities of capture, virtual population analysis, and yield and biomass per recruit) of selected major fish species;

3. To enhance and standardize the National Stock Assessment Program (NSAP) methodology and database;

4. To provide catch baselines that will be used to set reference points or harvest control rules which is a part of the Capture Fisheries strategy to implement science-based conservation and management measures as stated in the CNFIDP 2016-2020;

5. To provide limit reference points such as Exploitation (E) values and Spawning Potential Ratio (SPR) that will serve as guidelines in establishing harvest control rules for various commodity species.
