  abstract = {{U}sing trophodynamic models, the present study evaluated how a decade fishing closure inside and outside two marine protected areas ({MPA}s) in {S}enegal has influenced on the ecosystem trophic network. {S}cientific surveys in the {B}amboung {MPA} (68 km2, mangrove) were conducted since 2003, one year before fishery closure. {T}he resulting dataset was used to generate a time series of abundance indices, and {E}copath mass-balanced models were constructed for the 2003, 2008-2012, and 2015-2016 periods (one fished and two unfished periods, respectively). {T}hese three {B}amboung {MPA} models were subsequently used to evaluate the effects of fishing closure. {B}ased on the biomass trophic spectrum of the 2015-2016 model, the trophic structure of the {B}amboung {MPA} was compared to that constructed in the same period of an area that was still fished ({B}olong de {S}ankago). {U}sing a model based on ecosystem trophic levels ({E}co{T}roph) we simulated fishery activity in the {B}amboung {MPA} from 2008, to assess possible poaching in the {MPA}. {T}hen, the effect of fishing closure was also evaluated on the continental shelf for the {J}oal-{F}adiouth {MPA} (174 km2; sandy coast/mangrove), and comparing the trophic structure inside and outside of this second {MPA}. {T}he results showed that the {B}amboung {MPA} had high biomass, especially for higher trophic level species. {A}fter a decade of fishing closure, a 2-fold increase in predator biomass and a 1.5-fold decrease in prey biomass was recorded. {T}he models showed that poaching effects exist both studied {MPA}. {S}o official fishing closure had after a decade a lower effect in both {MPA}s. {F}or the {J}oal-{F}adiouth {MPA}, low-mobility species had high biomass, suggesting that high habitat diversity and fishery closure had a positive effect. {H}owever, the biomass of large species from high-trophic-levels was still low inside this {MPA}. {T}he obtained results could serve as a reference for future studies in this {MPA}. {I}n conclusion, fishery closure increased the total biomass in the {MPA}s over the medium and long-term; however, the trophic network might also be modified by high natural variability in the annual recruitment of some stocks.},
