European marine fish farming focused on the couple seabream and seabass. Species diversification is sustained by a better adaptation to local environments, to rearing techniques recently developed and to the new market trends, but also by an increase in rearing performance. Seabream and seabass have been chosen taking into account a limited number of parameters. The performance in both species of growth rate, fillet yield or adaptation to the processing industry requirements, for example, remain limited compared to those observed in some "new species". A selection work for "new finfish" candidates for aquaculture has been recently carried out in France. Cod was selected as the first candidate for aquacultural development on the western coasts of France (Atlantic, Channel and North Sea coasts). Halibut, wreckfish, dentex, pagrus or tuna might add value to other geographical zones.
