Aquaculture or sea farming,as it is sometimes called----is one of the brightest hopes for finding an answer to the problem of a world food shortage.Although it may be years before aquaculture yields really large quantities of food,it is already partially successful.One of its successful is the growing of oysters.
Oyster farming is a big new business on Cape Cod,where the first large crop of oysters was harvested last October.The waters there were famous for delicious oysters until the supply gave out about fifteen years ago.“There’s a whole generation of people who have never eaten oysters,” says Karl Touraine,marketing director of Aqua Dynamics Corporation,a company that grows oysters on strings hanging from metal racks.“For about twenty years the oyster has been in short supply,and our aim is to reverse this by using new,modern growing techniques,”he explains.
“Wareham,on Cape Cop,is the first place in the United States where oysters are being grown on racks in the off-bottom method,” says Hank McAvoy of the National Marine Fisheries Service in Gloucester.”But there’s nothing new about off-bottom raising,”Mr.McAvoy adds.”It’s been done successfully in Norway and Australia and,in the last few years,in Spain.The Japanese have used this form of aquaculture for years,and they’re the most successful,with a yearly crop of forty-six thousand pounds of shelled oyster to the acre.”
The Aqua Dynamics group grows oysters on strings,away from the bottom so that the oysters’natural enemies cannot reach them.‘When an oyster can avoid enemies and live in unpolluted water with plenty to eat,he’ll grow nice and fat in four years,” Karl Touraine explains.” Oysters will fasten themselves onto almost anything they can,” he continues.”At Wareham,we use shells,which we thread onto nylon strings hanging from metal racks.We lower the strings into the water,leaving at least a foot of water between the lowest shell and the bottom.
“So far the growth has been excellent and the taste just delightful,” Mr.Touraine notes happily.
