The map below shows the journey of four bluefin tuna that were tagged and tracked in 2008 as part of the 'On the Med Tuna Trail' project. The tuna were named: Shalim, Yarikh, Kotha, and Yamm – after Phoenician gods. Bluefin tuna have been caught in the Mediterranean for thousands of years.

Why tag and track bluefin tuna?

The population of reproductive adults of the eastern Atlantic population of bluefin tuna is currently less than 40% of the level it was in the early 1970s.

In this crisis situation, fisheries managers require solid tools – such as accurate and up-to-date information on the biology and ecology of bluefin tuna – in order to develop a successful and effective recovery plan.

The results of the WWF tagging project in the Mediterranean are expected to greatly assist in this feat, by providing valuable scientific information on the migratory routes, daily behaviour, reproduction, and even swimming depth of bluefin tuna individuals.
