Production de naissain de bivalves à moyenne échelle : buts et perspectives

This issue could be tackled from two different point of views: It was indeed possible to turn towards the Japanese techniques (semi-intensive experiments using large volumes superior to one cubic metre, providing immediate results but hardly repeatable, with a need for a large and non-specialized manpower), or to go for the enclosed system with a high controlled production (long implementation, heavier immediate investment, use ,in series, of small volumes with high concentrations, artificially produced natural food provided in known quantities, lower manpower needs but highly specialized). For a better knowledge of the issues raised and an easier future adaptation to the European socio-economic context, considering the knowledge brought by the Anglo-Saxon scientists, we decided to go for the second option.
