Mapping of potential fishing areas of Sardinella aurita in the Ivorian exclusive economic zone (EEZ) from 2010 to 2020

Abstract

The study we are conducting relates to the Exclusive Economic Zone fishing activities for small pelagic fish (EEZ) Ivorian. This zone is prone to strong in particular the Sardinella aurita whose localization is sometimes difficult because of their strong migration. The methodology used is based on combined analysis of remote sensing data variables ocean biophysics and Sardinella aurita fishing data. The implementation of all these data in a GIS from multi-criteria analysis by linking variables oceanic and fishing data has made it possible to show that the most influential oceanic biophysical parameters in determining the availability zones of Sardinella aurita are temperature (SST), salinity (SSM) and Chlorophyll-a. In addition, the great cold season is the period of the year most predisposed to a better availability of Sardinella aurita in the Ivorian EEZ.
