  abstract = {{I}n the {W}est {A}frican region, the marine protected areas '{MPA}s' were primarily created with conservation objectives, to protect emblematic species and critical habitats. {I}n the last ten years, their use as fishery management tools has also been advocated, particularly in {S}enegal. {T}his study aims to assess the observed changes in the fish populations' structures in the years following fishing bans. {T}he study is conducted in the {MPA}s of {B}amboung and {J}oal-{F}athiouth, in {S}enegal. {W}e described and analysed the fish assemblage structures using the data from two years' experimental survey (2015-2016). {I}n the {B}amboung {MPA}, an increase of total fish biomass and of maximal fish length has been registered after the fishing ban. {B}ut over the 2004-2016 period, these indicators globally fluctuated. {T}he contribution of marine affinity species has increased in depends of the estuarine part of the assemblage. {I}n addition, the trophic structure has been modified with an overall increase of the mean trophic level, resulting from an increase of the percentage of generalist or piscivorous predators and a sharp decrease of herbivorous and detritivorous species feeding in the low trophic levels. {M}arine predators which abundance and size were reduced by fisheries were again important components in the {B}amboung {MPA}. {F}or the {J}oal-{F}adhiouth {MPA}, the fish biomass increased within the reserve with a dominance of small size fishes. {T}his {MPA} leaded the conservation of certain species, but does not allow the proliferation of large size and high trophic level species. {T}he results of the multivariate analysis showed an increase of abundance of the estuarine affinity species to the detriment of marine species. {I}n addition, the low-trophic level species as herbivorous are more important in the reserve due to the high habitats diversity (mangroves, sandy and muddy bottom, algae) and the fishing ban effects. {I}n summary, we argue that the total ban on fishing in the estuarine area can significantly improve the fish assemblage for the fishing, and this is not evident for a coastal and marine area like {J}oal-{F}adiouth {MPA}.},
