The bonga shad (Ethmalosa fimbriata Bowdich, 1825) is the third most-exploited of the small pelagic species fished from coastal waters of Senegal (after Sardinella aurita and S. maderensis) and is routinely consumed by Senegalese people. Bonga shad fishing is practised mainly by artisanal fishermen and of great importance to the Senegalese economy and food security in the region. Our study was designed to examine population dynamics of bonga shad to support the development of fishery management options that may improve the livelihoods of artisanal fishermen. The current rate of exploitation (E = 0.8) suggests that the bonga shad in Senegal is over-fished. In addition, we describe seasonal variability in recruitment and biomass of bonga shad along the Senegal coast, its downward trend in landings over a 17-y study period, and its decline (18%) in maximum size over a 63-y period. We attribute the declines to an increase in fishing pressure and/or changes in local climate. To reverse the effects of overexploitation of the bonga shad stock, it will be necessary to drastically reduce fishing effort, apply and enforce regulatory restrictions on the capture, sale and processing of juveniles, and prohibit seiners and monofilament nets in the fishery. specialized Artisanal fisheries Data poor fisheries Fisheries management Small pelagic West africa SENEGAL AFRIQUE DE L'OUEST ATLANTIQUE 040 24 165-173 2018 2352-4855 https://www.documentation.ird.fr/hor/fdi:010074398 10.1016/j.rsma.2018.08.003 2352-4855 [F B010074398] https://www.documentation.ird.fr/hor/fdi:010074398 https://www.documentation.ird.fr/intranet/publi/2018/11/010074398.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2018-12-06 2023-07-11 fdi:010074398 fre
