Seston distribution studies during the Great African Expedition in Moroccan and Mauritanian waters in 2024-2025

The article reviews and analyzes data on seston distribution in the exclusive economic zones of Morocco and Mauritania obtained during the Great African Expedition in 2024-2025. A certain coincidence between seston distribution and ocean surface temperature is shown. It is noted that the distribution and formation of plankton-eating fish aggregations is largely determined by the availability of food resources, and increased seston concentrations are an indicator of food availability. The studies have confirmed that high seston concentrations can be indicators of the presence of commercial pelagic fish aggregations.
