Heaven on the half shell for oyster fanciers lies ready for the tasting after a shucking knife has pried open the plump Chesapeake bivalves. Piled high with oysters, skipjacks raft up to a buy-boat that will seed the immature shellfish in protected beds. The state pays dredgers and car rier for off-season transplanting. In three to four years the oysters grow to harvesting size (above). 808 Last winter they brought $3 to $6 a bushel.
