This symposium will focus on the evaluation of the IOTTP so far. Today more than 31,500 tags have already been recovered in this project. This has given new insights into the spatial and migratory movements along with population dynamics and the biology of tropical tuna species such as Yellowfin, Bigeye and Skipjack. The latest results of this research which will be presented at the symposium will hopefully allow a debate on the relationship between science and management which should in turn lead to improvements in long-term sustainability, a fundamental objective in the EU's reform of its Common Fisheries Policy (CFP). The reformed CFP also advocates closer working partnerships with regional fisheries management organisations (RFMOs), in this instance the Indian Ocean Tuna Commission (IOTC). As the world's leading market for fisheries and aquaculture products, the EU looks forward to the findings of the symposium, which will be an important indicator on the status of Indian Ocean tropical tuna stocks.
