%X In Senegal, the coastal pelagic resources occupy a leading place in the landing and are mainly constituted by both sardinella species, horse mackerels, mackerels and ethmalosa. On average, they represent about 70 to 80 % of the global annual catch. The exploitation of these resources is mainly done by the small-scale fisheries. The pelagic resources follow a migratory pattern in the South part of the Canary Current Large Marine Ecosystem area located between the South Senegal and South Morocco. It is thus a shared fish resource and their management is made at a sub-regional level within the framework of the Workgroup Fishery Committee for the Eastern Central Atlantic (CECAF) under the supervision of the FAO. The current state of these resources in the light of our last annual acoustic assessment survey led in January, 2015 on Senegalese continental shelf, on the framework of the Preface project is presented in this work as well as the historic series of the biomasses estimated by the FRV Fridtjof Nansen vessel in Senegal over the last twenty years. All the acoustics surveys carry out was completed with physical measurement with CTD probe (temperature and salinity profile) and sometimes ADCP (current). At the sub-regional level, the last management measures delivered by the Workgroup CECAF are presented and state an overexploitation of the main Senegalese stocks of small pelagics i.e. Sardinella, horse mackerels, mackerel, anchovy and ethmalosa, with the exception of the sardine, the biomasses of which are not significant in Senegal until now.  This work led independently by Senegal allow to discuss the effect of the departure of the last industrial foreign fisheries in 2012 which targeted small pelagics and also the potential effect of climate change as the 2015 survey complete the Nansen series, stopped in 2006, to get an 20 years overview.
