Fishing, if sustainably managed, plays a crucial role in providing jobs and feeding the world. However, the exploitation of potential fishery resources is still underutilized in the fishing industry. Fish catch in the Potential Fishing Zones (PFZs) is 3 to 4 times higher when compared to non-PFZ areas. Remote Sensing (RS) provides reliable data on oceanographic conditions and supports marine environmental monitoring and assessment. This research aims to highlight the efficiency of remotely sensed data and advanced satellite image processing techniques to determine PFZs using Geographic Information Systems (GIS). The study focuses on the distribution of chlorophyll-A (Chl-A), sea-surface temperature (SST), and Particulate Organic Carbon (POC) concentrations, using MODIS (Moderate Resolution Imaging Spectro radiometer) satellite imagery with are solution of 4km. The methodology was implemented in Moroccan waters as a case study from January to December 2021. The results indicate that the suspected PFZs are between September and December 2021, mostly found in the region of Dakhla Oued Eddahab in the south of Morocco. The results were compared to the fishing catches given by the Ministry of Agriculture, Maritime Fisheries, Rural Development, and Waters and Forests of Morocco (published on 12/09/2022).
