Les bases zootechniques et biologiques de l'élevage des poissons marins

In this synthesis of nearly 30 years of research on marine fish breeding (turbot, Scophthalmus maximus; sole, Solea solea; bass, Dicentrarchus labrax and sea bream, Sparus aurata) we present the main results acquired during the three periods devoted (1) to establishing zootechnical bases of marine fish breeding in general, theme 1, (2) to developing compound feeds adapted to young stages and optimising the feeds for juveniles, theme 2, and finally (3) to studying the impact of environmental factors on the growth capacity of sea fish juveniles, theme 3. Some references relating to the preliminary work on sea fish farming are given at the end of the report as well as, for each stage of this research, articles considered as the most important. The progression of the results obtained since the end of our work related to themes 1 and 2 is, by choice, merely mentioned. The continuation of work on theme 3, a study of the ability of turbot and bass to adapt to environmental conditions, viewed from several different angles, is proposed (adaptation and breeding systems, adaptation and well-being of the fish and interactions between adaptation and nutrition/genetics) with an extension to new species of interest to aquafarming.
