Resumo: | While the current stock status of bluefin tuna (BFT) has been considered as declining, there remain considerable data limitations for its stock assessment in the Mediterranean Sea. The collection of fishery-independent data reveals to be crucial to compensate for the lack of Mediterranean purse seine CPUE indices as well as to overcome a potential halt in the bluefin tuna fishery that would impede the monitoring of the stock and the comparison to reference points. Here we present a retrospective of aerial surveys that have been carried out since 2000. It includes the protocol as well as a retrospective of temporal and spatial distribution of detected schools. We then propose several perspectives that could improve the data collection method itself and the statistical method. By coupling information on bluefin tuna ecology, e.g. location and size of schools, with biotic and abiotic data (thermal and primary production fronts, prey distribution and abundance), perspectives offered by aerial surveys are particularly interesting in the framework of the Ecosystem Approach to Fisheries that has to be applied by 2012.
