The reproductive parameters were quantified from the macroscopic examination of the gonads and from the counting and measurement of the oocytes. The monthly variation of the condition factor was similar at both sites. The strongest condition coefficients were observed during the two major seasons (cold and warm) and the lowest during the transition period (warm - cold). A. latiscutatus had only one breeding season from March to July. Size at first sexual maturity varied by gender and site: 400 mm for females and 448 mm for males inside the MPA, and 419 mm for females and 375 mm for males outside. Absolute fecundity was 29 ± 14 oocytes and relative fecundity 0.024 ± 0.007 oocytes per gram within the MPA. Outside, absolute fecundity was 22 ± 10 oocytes and relative fecundity 0.027 ± 0.005 oocytes per gram. The MPA appeared to be the privileged spawning area of the species, an area where reproductive activity would be more intense and fertility higher. Additional analyzes based on a larger sample and integrating other parameters such as age estimation, growth and diet, will allow to complement these initial results and to specify the impact of the reserve on the biological parameters of the species but also to have a global knowledge of its life traits. specialized SENEGAL ATLANTIQUE 040 021 ICAWA : International Conference AWA, 3., Dakar (SEN), 2016/12/13-15 113 Brehmer Patrice ed. edt IRD Ba B. ed. edt IRD Kraus G. ed. edt IRD Dakar SRFC/CSRP 2017 https://www.documentation.ird.fr/hor/fdi:010072140 978-2-9553602-0-5 [F A010071832] https://www.documentation.ird.fr/hor/fdi:010072140 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers18-01/010072140.pdf IRD - Base Horizon / Pleins textes 2018-01-30 2018-02-05 fdi:010072140 fre
