This drives some populations to create reproductive strategies to ensure the survival of their offspring. The analysis of comparative functional responses can be used in different contexts to improve the understanding and prediction of the environmental impact on small pelagic population fecundity (PF). Successful recruitment into a population is subject to variations in fecundity. Significant seasonal and inter-annual differences in PF of Ethmalosa fimbriata in southern Senegalese coastal waters could be observed. Here we show that the population is able to fit its spawning tactic to variable conditions in an upwelling environment. It appears that E. fimbriata aims at spawning in water temperatures of around 24°C and at an upwelling intensity of 3 m3 s-1 m-1. Understanding the spawning tactics of an highly exploited fish species is important in the context of climate change to get efficient forecast in countries where fisheries is crucial at socio-economical level, in order that decision maker can provide ad hoc adaptation plan for the fisheries sector. specialized AFRIQUE DE L'OUEST SENEGAL ATLANTIQUE 040 021 030 ICAWA : International Conference AWA, 5., Lanzarote (ESP), 2018/04/17-20 136 Brehmer Patrice ed. edt IRD Diogoul N. collab. clb IRD Zenk C. collab. clb IRD Vareilles M. de collab. clb IRD Keenlyside N. collab. clb IRD Nascimento J.M. collab. clb IRD Ramos V.
