| Ocinebrellus inornatus is an important predator on seed-oysters in Pacific Oyster aquaculture in Atlantic France (Goulletquer et al. 2002). Although it has a lower feeding rate than the native European Oyster Drill (O. erinacea), it has a higher reproductive output and a longer breeding season than the native, and the potential to consume more oysters (Martel et al. 2004c). In newly colonized areas, eradication was attempted, but appears to have been unsuccesful. The methods included: '1) destruction of the ovigerous capsules using propane burners; 2) incentive harvest operations in the intertidal zone; and 3) pot fishing using oyster meat like bait. Today, the species is present from Brittany, except perhaps for Finistère, to Arcachon Bay' (Stiger-Pouvreau and Thouzeau 2015). | ||
