Ifremer has developed or is involved in several projects, which aim at helping to understand the migratory dynamics and biology of Atlantic Bluefin tuna.
If we don't see many tunas during the aerial survey, does it mean there are not many tunas in the sea or does it mean they moved somewhere else ? Is the environment affecting such movements ? Tagging activities allow to understand individual behaviour and to answer such questions. Ifremer has been leading tagging activities in the Mediterranean for a very long time and has current activities in the Gulf of Lions, in the Atlantic and on the Maltese spawning ground.
