Abstract = {{The impact of the fishing effort exerted by a vessel on a population
   depends on catchability, which depends on population accessibility and
   fishing power. The work investigated whether the variation in fishing
   power could be the result of the technical characteristics of a vessel
   and/or its gear or whether it is a reflection of inter-vessel
   differences not accounted for by the technical attributes. These
   inter-vessel differences could be indicative of a skipper/crew
   experience effect. To improve understanding of the relationships,
   landings per unit effort (lpue) from logbooks and technical information
   on vessels and gears (collected during interviews) were used to identify
   variables that explained variations in fishing power. The analysis was
   undertaken by applying a combination of generalized additive models and
   generalized linear models to data from several European fleets. The
   study highlights the fact that taking into account information that is
   not routinely collected, e. g. length of headline, weight of otter
   boards, or type of groundrope, will significantly improve the modelled
   relationships between lpue and the variables that measure relative
   fishing power. The magnitude of the skipper/crew experience effect was
   weaker than the technical effect of the vessel and/or its gear.}},
