Relative abundance index of bluefin tuna (Thunnus thynnus) caught by the Moroccan traps in the Atlantic area close to the Strait of Gibraltar was updated up to 2014. The annual Standardized index was estimated through a General Linear Modeling (GLM) approach under a negative binomial error distribution assumption. A remarkable increase of the index has been observed since 2012, reflecting probably an improvement of the EABFT stock spawning biomass.
