Brazil has approximately 8,500 km of coastline and a reasonable number of islands, totaling an area of ​​approximately 3.5 million km² of Exclusive Economic Zone (EEZ), which extends from Cape Orange (5 oN) to the Chui (34 oS). Surface longline fishing is a fishing modality used worldwide in the open ocean. Currently the main ports that host the longline fleet in the Southeast region in Santos (SP) and Itaipava (ES) and in the South region the locality of Itajai and Navegantes (SC). The blue shark, Prionace glauca (Linnaeus, 1758), is one of the species of pelagic elasmobranchs, most captured by the surface longline fleet. The blue shark is considered to be the abundant among the great pelagic sharks present in the Atlantic Ocean. It is an oceanic species, highly migratory, with global distribution, between 60 ° N and 50 ° S latitudes, occurring in tropical and temperate waters, predominantly in those with temperatures between 12 ° C - 20 ° C. The present study aims to evaluate the influence of meteo-oceanographic variability in the southwest Atlantic Ocean on the population of blue shark, Prionace glauca (Linnaeus, 1758), captured by the industrial fleet in the period 1994-2018 in the surface longline modality. For the preparation of the study, the monthly landings data for the South American Atlantic longline fleet between the years 1994 - 2018 will be analyzed.
