An approach to map and quantify the fishing effort of polyvalent passive gear fishing fleets using geospatial data

Abstract The use of tracking devices, such as vessel monitoring systems or automatic identification system, enabled us to expand our knowledge on the distribution and quantification fishing activities. However, methods models based data are mostly devised be applied towed gears, whereas applications multi-gear passive fisheries have been underrepresented. Here, we propose a methodology deal with geospatial map quantify effort, soak time, gears used by fleet. This approach can adapted other multi-or single-gear fisheries, since it requires only three variables that extracted from pre-classified dataset, identify beginning (gear deployment) end (hauling) events. As far aware, this is first time allows quantifying static events, within polyvalent fishery context, presented. We argue information approaches could contribute improved management static-gear ecosystem-based approach.
