  abstract = {{T}he drifting {F}ish {A}ggregating {D}evice (d{FAD}) purse seine fishery is complex and fishing effort depends on a multitude of factors. {T}raditional indices of fishing effort such as searching time are meaningless for this fishery. {W}e composed a comprehensive list of 28 candidate variables that describe the d{FAD} fishery and used them as predictors of fishing effort in bigeye tuna {CPUE} standardization of the {F}rench purse seiners operating in the {E}astern {A}tlantic {O}cean during 2007-2013. {W}e performed variable selection using penalized maximum likelihood in {GLM} and {GLMM} frameworks, aiming to improve prediction accuracy and interpretability of the selected models. {W}e applied the {L}asso ({L}east {A}bsolute {S}hrinkage and {S}election {O}perator) regression models to derive the true parsimonious model, because the number of candidate independent variables is large compared to the number of observations. {T}he penalized model selection process retained explanatory variables such as: the skipper, the vessel, the price of targeted tuna species, the density and spatial distribution of {FAD}s and the number/type of deployed buoys. {T}he inclusion of these predictors in {CPUE} standardization models provided realistic estimates of uncertainty. {W}e propose the systematic collection of selected explanatory variables and their usage in d{FAD} related tuna {CPUE}s standardization in a mixed model framework.},
