Abstract

Pakistan's Exclusive Economic Zone (EEZ) is blessed with a broad spectrum of marine life. Identification of such potential fishing zones (PFZs) can be highly profitable for sustainable fisheries by complementing to their catch and efficiency. Advancements in satellite remote sensing have made their way into marine environmental monitoring and assessment by providing reliable data about oceanographic parameters. The objective of this study is to identify PFZs using three of the crucial marine parameters, including Sea Surface Temperature (SST), Chlorophyll-a (Chl-a) and Particulate Organic Carbon (POC) concentrations. EEZ of Pakistan has been subjected with Moderate Resolution Imaging Spectroradiometer (MODIS) satellite images for a temporal window, consisting of January to December 2022. The outcomes of the study reveal that during January, February and March, the PFZs within EEZ of Pakistan is found filled with categories good and premium fishing zones, while a sharp decline is observed till the month of August due to the southwestern monsoon. In the later part of the year, PFZs starts to stretch its boundaries along the coastal area, which gradually expands in the whole EEZ with the succeeding months of the year. These results are further validated with the help of fishing activity data from Global Fishing Watch (GFW) and is also supported with meteorological data over EEZ. The study provides a cost-effective method using satellite remote sensing to identify PFZs; however, highlighting the importance of catch data accuracy for validation of PFZs distributions.

期刊介绍： Continental Shelf Research publishes articles dealing with the biological, chemical, geological and physical oceanography of the shallow marine environment, from coastal and estuarine waters out to the shelf break. The continental shelf is a critical environment within the land-ocean continuum, and many processes, functions and problems in the continental shelf are driven by terrestrial inputs transported through the rivers and estuaries to the coastal and continental shelf areas. Manuscripts that deal with these topics must make a clear link to the continental shelf. Examples of research areas include: Physical sedimentology and geomorphology Geochemistry of the coastal ocean (inorganic and organic) Marine environment and anthropogenic effects Interaction of physical dynamics with natural and manmade shoreline features Benthic, phytoplankton and zooplankton ecology Coastal water and sediment quality, and ecosystem health Benthic-pelagic coupling (physical and biogeochemical) Interactions between physical dynamics (waves, currents, mixing, etc.) and biogeochemical cycles Estuarine, coastal and shelf sea modelling and process studies.
