NCCOSscientist, Suzanne Bricker, spokeat the 2017 East Coast Commercial Fishermen’s and Aquaculture Trade Expo seminar program on January 14, 2017. Collaborating with Maryland Sea Grant, the presentation ‘ Oyster Best Management Practices: What does it mean for growers ?’ highlighted the recently approved recommendations for crediting oyster tissue for nutrient removal as a Best Management Practice (BMP), with a focus towards ongoing research in support of the Oyster BMP Expert Panel’s continuing evaluation. Jurisdictions within the Chesapeake Bay watershed can now include harvested oyster tissue as a nutrient reduction BMP in their watershed implementation plans to fulfill required nutrient reductions. Studies have shown that 65% of US estuaries, and all within the Chesapeake Bay region, are moderately to severely degraded by nutrient input.
Potential use of oysters as a nutrient BMP is of great interest, as there is already a thriving oyster industry in the Bay that could expandfor nutrient reduction purposes in addition to provision of seafood. While there is presently no mechanism to pay oyster growers for the ecosystem service provided by their farms, the nutrient removed by harvested tissue can now be counted toward nutrient reduction goals. Development of a payment protocol within the larger nutrient credit trading program requires additional research and planning. However, growers who receive credits may see positive impacts now through marketing that can potentially generate higher prices or more sales depending on market or customer base.
