The existing knowledge about the nutritional aspects of the Mediterranean yellowtail (Seriola dumerili, Risso 1810) is reviewed in this presentation. Data about natural food and feeding habits of young and adult fish are presented due to its potential application for developing farming techniques. Research trials conducted at our laboratory using moist and soft-dry pellets as food for young S. dumerili have resulted in better growth and conversion factor and even survival rate than raw fish. For the practical diet formulation, some experiences with the use of different protein and lipid sources in extruded diets for S. dumerili have also been carried out in collaboration with other Spanish research centres. Preliminary trials with protein and lipid and the protein per energy rate requirements carried out in collaboration with the Universidad Politécnica de Valencia are presented. Finally, future prospects and research topics will be pointed out and compared with the present trends in Japan.
