ABSTRACT: This study concerns the density and biomass of the ichthyoplankton population in the estuaries and mangroves of Sangaréah Bay. The study resulted in the inventory of 5938 individuals divided into 20 families and 30 species, more dominated by the Carangidae, Clupeidae and Sciaenidae, which each account for 10% of the species total population. A high concentration of planktonic ichthyo organisms was observed in the Sonfonia, Samatran, Soumba and Arabanty areas. In short, the constant presence of eggs and larvae of ontogenetic stages make these estuary and mangrove zones environments of advection, migration, ontogenetic development and feeding. Ichthyoplankton is one of the modern tools used in the bio-indication and bio-monitoring of aquatic ecosystems. A diverse population dominated by fish eggs and larvae is a sign that the ecosystems surveyed are functioning properly.
