In the frame of the SELFDOTT project (From capture based to SELF-sustained aquaculture and Domestication Of bluefin tuna, Thunnus thynnus) captive-reared Atlantic bluefin tuna housed in captivity for 4 years in El Gorguel (Cartagena, Spain) have produced massive spawning, during the natural spawning period for this species in the Mediterranean Sea (June-July) since 2009. Egg collection was accomplished by placing a special curtain around the perimeter of the cage and with collection taking place at night and at sunrise using nets from the surface of the water. Larval rearings were done using pseudogreenwater technique. The survival was of 73 days in 2009 and 110 days in 2010. In 2011 several thousand one month old fingerlings have been produced being transported to floating cages.
