  abstract = {{F}acing the loss of fish biodiversity and the decrease of fish stocks since several decades, a proposed solution is the multiplication of {M}arine {P}rotected {A}reas ({MPA}). {I}n {S}enegal, one {MPA} has been implemented in 2003 in one of the channels composing the {S}ine {S}aloum estuary. {A} monitoring program was carried out based on hydro-acoustic survey and the two main metrics extracted from hydro-acoustic data: {F}ish biomass proxy and fish size distribution proxy. {T}he surveys were performed using vertical beaming at different seasons from 2003 to 2010. {I}n the {MPA}, a light increase of the fish biomass proxy and an increase of the fish size proxy during the dry season were observed. {T}he biomass proxy recorded in a close but not protected tributary were higher than in the {MPA}, probably due to a strong connection with open marine water, aggregative behavior of preys in the {MPA} due to higher predation, and a stronger avoidance phenomenon in the {MPA}. {T}he high variability of the {MPA} environment submitted to both estuarine and marine influences and the size of the {MPA} may explain the lack of clear results. {H}owever, the learned lessons enable us to make recommendations to monitor fish population in {MPA}s using hydroacoustic methods. {E}valuation procedures using these methods are proposed highlighting the importance of a rigorous survey protocol to insure the exploitation of the entire acquired time series.},
