The protocol and the sampling design were established by IFREMER and the operations were carried out by two independent scientific observers (each one following a given boat over two distinguished fishing seasons). The 788 BFT measured by the two observers during the ~ 190 fishing days were mostly small/juveniles fish and solely represented 2.7% of the total catches. The sampling appears largely insufficient to be representative of this fleet and was furthermore strongly biased (big BFT being under-sampled). From our viewpoint, the implementation of a joint observer program on... Tipo: Text Palavras-chave: Atlantic bluefin tuna; Catch; Size composition; Observer; Purse seine; Mediterranean; By-catch.
