A new report says Chesapeake Bay oysters appear to be becoming more resistant to diseases that have harmed their populations in recent years.

The Chesapeake Bay Foundation report released Tuesday also calls for increasing oyster sanctuaries, reef building and anti-poaching efforts to promote resistance.

The report is based on a review of recent research, state data from Maryland and Virginia and interviews with oyster experts.

Maryland released an oyster restoration plan in May calling for putting 25 percent of oyster reefs off limits to harvesting.

The bay foundation report calls for Virginia and Maryland to create sanctuaries protecting about 40 percent of historical oyster grounds.
