  abstract = {{I}t is necessary to refine the acoustic estimation method applied in the {G}ulf of {C}alifornia, especially regarding the acoustic energy allocation to the different species coexisting in the same area, in order to produce a more precise and reliable fishery independent biomass index for the sustainable management of the fishery. {T}he series of acoustic surveys carried out in this work are the first systematic attempts to estimate {P}acific sardine biomass in the {G}ulf of {C}alifornia. {D}ue to similar acoustic reflectivity of other pelagic species, we need to refine the allocation of acoustic energy to species. {F}rom 2012, besides the 38 k{H}z transducer another frequency has been incorporated (120 k{H}z) in the surveys. {W}ith both frequencies we will apply acoustic signal filtering procedures in order to 1). {D}iscriminate zooplankton echoes from fish echoes and 2). {I}nvestigate the possibility to better discriminate the {P}acific sardine from other species.},
