Jurisdictions to Get Pollution Credit for Oyster Aquaculture?

Bay Program partners approve oyster aquaculture as best management practice

Watershed jurisdictions could get pollution-reduction credit for their oyster aquaculture industries after the Chesapeake Bay Program’s Water Quality Goal Implementation Team approved findings put together by the Oyster BMP Expert Panel. This panel, coordinated by the Oyster Recovery Partnership, is made up of oyster scientists and practitioners, and includes representatives from academic institutions, non-profit organizations and county, state and federal agencies.
. . .
The panel’s report specifies how three forms of oyster aquaculture could help reduce pollution and recommends their designation as best management practices (BMPs), or practices that reduce or prevent nutrients and sediment from entering the Chesapeake Bay.

Some verbiage explicating how oysters help clean the water skipped. If you don't understand that, go elsewhere.

The protocols approved in the report will become available to state and local governments as options to implement or promote—the same way that establishing forest buffers or planting cover crops are. The Chesapeake Bay Program partnership is now developing procedures for the implementation and verification of the new BMP.

While the panel’s recommendations apply only to private oyster aquaculture, experts will continue to look into options for public reefs and oyster sanctuaries, as well as other ways oysters could reduce pollution, and will publish their findings and recommendations in future reports.

My question is why the jurisdictions should get credit for the pollution reductions for oysters they barely had anything to do with planting? Why shouldn't the actual oysters farmers be given the credits, which they should be able to sell to others seeking to buy credits to allow them to release more.

Turn this around, and why shouldn't we be taxing watermen who harvest wild oysters more because they're removing a pollution removal system from the water?
