Resumo: | This study is the second part of a former report rapport Ifremer DRV/RST/RA/LCB/2002-08 dealing with rearing methods, growth and mortality performances, and problems encountered by the oyster farmers from Quiberon Bay (2800 ha of leases) : the first report relied on a survey achieved in july 200l, about 18 oyster farmers, and 2 diving campaigns (july and october 2001) on 2 years old oyster batches from the same farmers. Il is now completed by a last campaign of diving in october 2002, on 7 parcels out of the 18, still bearing the initial oysters. The analysed enterprises vary in particular by the location and depth of their concession inside the bay, but also by their rearing scheme : a majority favours seedings with 18 month old oysters or more, according to prices and availability of oysters supplies. This part of the study provides in particular a tool of profitability simulation, based on technical (growth, survival) and economical (prices of different oysters categories) hypothesis. Theses references may be used in ecosystem studies or long run monitoring of the area.
