Contribution to the study of the ichthyoplankton population of the estuary and mangrove areas of sangaréah bay

This study concerns the fish population of the estuary and mangrove areas of the bay of Sangaréah carried out from January 2015 to December 2016, at the rate of a monthly sample, carried out in the first week of each month. The methodology used by (7) has been used for qualitative and quantitative studies of ichthyoplankton. Thus, the study made it possible to inventory 5938 individuals divided between 20 families and 30 species, dominated by the Clupeidae (26%). The high concentration of ichthyoplanktonic organisms is observed in the areas of Sonfonia, Samatran, Soumba and Arabanty. In short, the constant presence of eggs and larvae of ontogenetic stages make these areas of estuaries and mangroves environments for migration advection, ontogenetic development and food. Ichthyoplankton is one of the modern tools used in bio-indication and bio-monitoring of aquatic ecosystems. Has diverse population, dominated by eggs and larvs
