Resumo: | The works carried out during this course (March-August 2015) alowed to correct the datasets and to study the variation in catches of albacore tuna from 1967 to 2014 (except for the years 1987 to 1990) based on 3 gears: the trolling line, the line with cane and the pelagic trawl. Simultaneously, key ICCAT delivred was provide information to expert groups, with a view to defining fishing quotas. Catches released and fishing effort (defined by the number of vessels and the time spent at sea) have varied considerably over these 50 years, and have been increasing in recent years, after having decreased sharply. Fishing today is concentrated on the edge of the continental shelf, whereas it was very oceanic before. It is mainly juveniles that are caught, while the stock is considered overexploited and threatened with extinction. This work constitutes a preliminary step towards the implementation of the standardization of this data, which wil be carried out  by the teams of NOAA and IFREMER of Réunion.
