Overall, there was a lower CPUE in upwelling months (December-April). For the 42 commercial species reported, most biomass was from the spotted rose snapper (<em>Lutjanus guttatus</em>; 22 % of biomass), the Pacific red snapper (<em>L. peru</em>; 18 %), groupers (<em>Epinephelus </em>spp.; 15 %) and octopuses (<em>Octopus </em>spp., 13 %). <strong>Conclusions: </strong>CPUE at Santa Elena has not declined significantly from 2010 to 2019, but it falls in the upwelling season.</p> ER -
