One-third of the oysters sold in the United States come from Louisiana. However, the places where oysters grow have been hurt by recent hurricanes, higher than usual amounts of fresh water coming down the rivers (oysters need salt water) and also the Gulf oil spill. The Louisiana Division of Wildlife and Fisheries have been working with scientists at universities on better ways to grow oysters. Also, in June, 2011, more than 100 million oyster seeds and 500,000 baby oysters were put in test areas to help the oyster areas to grow back.
