Eutrophication is the overabundance of nutrients in a body of water that results in harmful algal blooms, which can lead to depletion of dissolved oxygen and loss of fish and ...

Expanding the Southeast Alaska Tribal Ocean Resear...

This project expands existing harmful algal bloom (HAB) monitoring conducted by the Sitka Tribe of Alaska Environmental Research Laboratory (STAERL) to include testing shellfish for domoic acid and diarrhetic shellfish ...

Genomics of HAB Dinoflagellates: Identification of...

We are working to identify key genes and processes encoded in the dinoflagellate genome that are responsible for regulating the growth, maintenance, and termination of toxic dinoflagellate blooms. Analogous to ...

Histological Techniques for Marine Bivalve Mollusk...

To best manage marine resources such as bivalve mollusks (i.e., clams, oysters) and crustaceans (i.e., crabs), scientists must have access to the tools needed to study the health of these ...

Monitoring and Management of Lipophilic Shellfish ...

Lipid and fat soluble (lipophilic) algal toxins linked to diarrhetic shellfish poisoning and azaspiracid shellfish poisoning are emerging threats to recreational, subsistence, and commercial shellfisheries in the state of Washington ...

Oyster Aquaculture Related Ecosystem Services in t...

Eutrophication—the overabundance of nutrients in a body of water—threatens the normal function and benefits provided by coastal ecosystems. Attempts to reverse eutrophication have focused on reducing land-based sources of nutrients ...

Planning for Sustainable Shellfish Aquaculture in ...

Eutrophication is the overabundance of nutrients in a body of water that results in harmful algal blooms, fish kills, and in some cases ecosystem collapse. We are investigating the feasibility ...

Shellfish Aquaculture and Payment for Ecosystem Se...
