The main objective of this thesis was to determine the selectivity and efficiency of gillnets used in artisanal fishing in Puerto Pacasmayo. The study focused on the main species caught during the experimental outings carried out between February and May 2024. Nets of different mesh sizes were used and the Holt method (1963), described by Sparre and Venema (1995), was applied to determine the selectivity of gillnets. In addition, the Kruskal-Wallis test and Dunn's pos hoc test were used to evaluate the differences in Catch per Unit of Effort (CPUE) between the different mesh sizes. Selectivity curves were estimated for the species Cynoscion analis "cachema" and Mugil cephalus "smooth". The selection factor (FS) was set at 4,57 for cachema and 4,23 for mullet. For cachema, the optimal lengths were 24,67 cm and 25,71 cm using nets with mesh sizes of 53,98 mm and 56,24 mm respectively, both below the Minimum Catch Size (27 cm). In the case of the mullet, the optimal lengths were 32,20 cm and 34,89 cm with surface nets with meshes of 76,20 mm and 82,55 mm, both below the Minimum Catch Size (37 cm). The CPUE showed statistically significant differences between mesh sizes, which could impact fishermen's short-term income. This research allowed us to know the effect of gillnets on two of the most important species for artisanal fisheries, as well as to evaluate their effectiveness and potential economic impact.
