Resumo: | In 2003, IFREMER implemented an observer program on board of the French purse seiner targeting bluefin tuna (BFT) in the Mediterranean Sea to collect the size composition of catches. 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 board of boats and cages would constitute the sole effective alternative, but this would imply international cooperation between several Mediterranean countries.
