Stomach contents from 19 dead young bluefin tuna were analyzed in the framework of the SELFDOTT project (From capture based to SELF-sustained aquaculture and Domestication Of bluefin tuna, Thunnus thynnus). The fish were captured close to Cartagena (Murcia- Spain) between the 3rd and the 16th of October 2008, using the «curricán» method (a Spanish term meaning to fish by trailing a baited line along behind a boat). The first stomach analyses show that cephalopods are the main prey (53% in weight 49% in number), followed by fishes (28%, 24%) and crustaceans (2%, 27%). The main prey species is the squid Illex coindetti.Proyecto SELFDOT
