As global demand for fish will probably double over the next 20-40 years, fish farming will have to develop without an unacceptable impact on the environment. Under these conditions, it must be based on progress towards genetic improvement and yield for energy conversion. In fact, food represents 40% to 60% of the cost of production of farmed fish. Therefore, emphasis should be placed on programmes that optimize both feed efficiency and growth. The bass (Dicentrarchus labrax) is an excellent model to conduct this study on. In fact, this is one of the emblematic fish of marine fish farming in the Mediterranean. In addition, a wide range of genomic resources are available, including information which allows a more accurate explanation of regions of interest for feed efficiency. The REGULBASS project will combine measurements of gene expression in order to help improve the process of domestication of fish farm varieties.
