Floodwaters carried down from the Midwest are killing oysters and driving crabs, shrimp and fish out of bays and marshes and into saltier waters. This means hard times for fishermen and others who make their living from the water.

Edwards says the declaration could help get federal aid for fishers, processors and docks, and for state rehabilitation of the species.

Mississippi's governor had asked earlier for a federal disaster declaration.

Floodwaters carried down from the Midwest are killing oysters and driving crabs, shrimp and finfish out of Louisiana and Mississippi bays and marshes to saltier waters.

So it's a bad year for many people who make their living from the water.

Brad Robin says his family controls about 10,000 acres (4,000 hectares) of oyster leases in Louisiana. He says that on a 10-point scale, "we are 9-and-a-half destroyed."

Mississippi's governor has asked the federal government for a fisheries disaster declaration. Louisiana Wildllife and Fisheries Secretary Jack Montoucet says Gov. John Bel Edwards is preparing a similar request. Both states have seen oyster harvests plummet by 80 percent, and shrimp landings are nearly as bad.
