Resumo:  Turbot, Scophthalmus maximus Rafinesque, 1810: Psetta maxima Linnaeus, 1758, is a marine demersal carnivorous flatfish of the Scophthalmidae family, relatively abundant in Europe: from 68°N down to Morocco 30°N. It is also abundant in the Mediterranean Sea as far as Turkey. But it is lacking in the Black Sea, where two very close species, S. maeoticus and S. ponticus, are naturally found (Figure 1). Turbot are caught on sand, gravel, or mixed bottoms at a depth of 20 to 70 m. The total annual catch is less than 10,000 for all Europe in spite of the high market price: from 10 to 25 U.S. $/kg according to the country and the size of the fish (0.65 to 15 kg). Turbot was selected for aquaculture in the early 1970s, both in the United Kingdom and France due to its commercial value and its potential growth rate in intensive conditions. Initially the main work was performed at state research centers including MAFF* and the former WFA** (now SFIA) in the U.K., and the former CNEXO*** (now IFREMER) in France. Efforts have been focused on larval rearing techniques, egg supply and live prey production. The first larval metamorphosis to juvenile stages in the laboratory was obtained in 1970 and 1972 in the U.K. and France, respectively. In contrast, the research efforts on the growout of juveniles has been limited in France, whereas in the U.K. sea-caught young turbot have been used by commercial companies for about 10 years to establish the basic growout techniques. In the last decade, in both the U.K. and France, significant progress has been made in understanding the nutritional and environmental requirements of turbot as well as in hatchery design and management. The development of turbot culture has been limited by the lack of high quality juveniles during the past decade. Only recently has this culture become a profitable business in the U.K
