As an experiment this Spring of 2009, we planted 10,000 seed Manila clams and 1,000 Triploid Oysters on a gravelly cobbly rather steep beach in Hammersley Inlet. This particular beach does not have the extremely high current velocities as the majority of the Inlet. Not knowing what to expect on oyster mortality, we used two grow-out bags at 500 spat per bag (too many), crossed our fingers and let them have at it. The bottom of these original bags was at exactly a +2.0 tide. In mid September it was obvious we had a space "problem". Growing like crazy, so I had two more empty bags and we did splits and a rough count and still had 1,000 oysters that were 3-4 in. long after 5 months (planted May 23rd) and the bags weighed at about 65 lb. each. Then more bags bought and now finally down to 8 bags of 125 per bag. 4 of these latest splits were moved higher on the ground and the bottom of these bags at +3.0 for easier winter access. We will have to keep them in the bags until next spring when we have some decent daylight tides to construct a fenced area to eliminate some bags ect. The beach is steep enough that oyster drift will occur laterally and downward. Unknown success or failure on the clams and that will be determined next spring but the oyster project a huge success with growth that a couple of commercials said was astounding for only 5 months.
