Considerations for Shell Use in Oyster Rehabilitation Assessing the Effectiveness of Multiple Options

There has been much concern regarding the precipitous decline in Mid Atlantic oyster production, with various groups attempting to place blame and espouse causes. However, it is instructive to veer away from traditional arguments to compare oysters with traditional agricultural crops for a different view of the problem and a vision for potential solutions. Comparing production of oysters with other crops allows us to examine how those have been managed over time to increase production. The United States today is considered a world leader in food production. Taking lessons from that development and applying them to oysters could help guide the restoration of the industry that once flourished.

Nutrient Credit Trading Could Expand Maryland Oyster Aquaculture

Researchers from the University of Maryland Center for Environmental Science (UMCES) conducted a study to evaluate the potential effect of nutrient credit trading on the growth and profitability of Maryland’s aquaculture industry. Nutrient credit trading is a market approach to lowering the cost of meeting the pollution caps that have been established to restore aquatic habitat in the Chesapeake Bay. Oyster aquaculture producers are eligible to sell credits in this emerging market, which creates the potential for economic and environmental benefits.
