Following the development of the hatchery tool, different triploidy induction techniques have been tried out in vitro. The method using cytochalasin B was selected and successfully applied to cupped oysters, Crassostrea gigas and especially to clams, Ruditapes philippinarum. Larval survival rates were lower than control rates. On the other hand, larvae's growth speed was comparable. These methods will now be used to produce significant test populations which will then be cultivated in French coastal waters.
