Les bancs naturels et la reproduction de l'huître plate en Morbihan

Natural beds of Ostrea edulis, long since decimated, began to repopulate the rivers of the Morbihan "département" in 1943. In 1955, I reported results acquired during the 1943-1954 period and highlighted the effects the repopulation seemed to have on oyster spat collection. It is thus useful to explore to what extent the population has grown and the influence that the renewed population success has had on the European flat oyster in bays and rivers.
