Spatial distribution of fishing effort in the Maritime-Terrestrial National Park of the Atlantic Islands of Galicia (PNMTIAG) in Galicia (Spain)

This file contains data of spatial distribution of fishing effort in terms of sets of gear/day or vessels/day in the PNMTIAG. Fishing effort has been calculated between 2016 and 2017 by mean of a stratified random sampling in three of the four archipelagos included in the park (Sálvora, Ons and Cíes). In the case of the Cortegada archipelago, given the smaller size of its marine area, a census was carried out over its entire surface for both passive fishing sets of gears and non-passive fishing vessels. More methodological details are exposed in Parada and Nieto (2024) (DOI: https://doi.org/10.1016/j.rsma.2024.103435).

The data set includes all the gears of artisanal fisheries employed in the park, excluding selfish fisheries (Except in Cortegada because of the great importance of Manual clam rake): Large-mesh trammel nets, Hoop nets, Spider crab pot, Velvet crab pots, Octopus pots, Cuttlefish pot, Handline, Bottom longlines, Set longlines, Manual clam rake, Trawl clam rake, Small-mesh trammel nets Large-bottom gillnet, Small-bottom gillnet, Set gillnets, Small purse seine-trawl, Sport fishing (not allowed into de park) and Crab hook.

The file is structured in eight columns: Grid, the name of the 500 x 500 m grid in which the maritime area of the park have been divided for sampling propose (see Parada (2024); doi.org/ 10.5281/zenodo.10466820); Archip, the archipelago; Gear, the name of the gear; Arte, Spanish name of the gear; f(sets_gear/d), fishing effort in terms of sets of gear/day for passive-gears or mean vessels/day por non-passive gears in each grid; X, longitude of the centroid of the grid; Y, latitude of the centroid of the grid; CRS, Coordinate Reference System for X and Y.
