Water Quality Improvements Through Shellfish Aquaculture Highlighted in NOAA Science Seminar Series

A recent presentation highlighted a new NCCOS modeling study in Long Island Sound (LIS) and Great Bay Piscataqua Regional Estuaries (GBP) that focused on the water quality benefits of shellfish aquaculture. The presentation, “Eutrophication and Aquaculture; Shellfish can help the Bay!,”reported nitrogen removal estimates through cultivation of oysters equivalent to 1% of total nutrient inputs discharged […]

NCCOS, Partners Improve Aquaculture Siting and Production in Puget Sound

NCCOS and partners are using computer modeling to determine the carrying capacity for shellfish aquaculture—and the related potential for nutrient removal—in South Puget Sound. The team’s methodologies and guidelines will be used to inform marine spatial planning activities locally and throughout the U.S., promoting sustainable shellfish aquaculture and providing a framework for addressing issues that commonly lead […]

New Fish Farm Siting and Management Practices Reduce Water Quality Impacts

Scientists with NOAA’s National Centers for Coastal Ocean Science (NCCOS) found that fish farm effects on dissolved oxygen and turbidity have been largely eliminated through better management, like using formulated feeds, minimizing feed waste, and properly siting farms in deep waters with flushing currents. The trend toward moving industrial-scale aquaculture into offshore waters is increasingly […]

AquaSpace: An Ecosystem Approach to Making Space for Sustainable Aquaculture

NCCOS joined a recently approved project “AquaSpace – Ecosystem Approach to making Space for Sustainable Aquaculture,” as part of the European Commission research topic “Optimizing space availability for European Aquaculture.” The project aims to increase space available for aquaculture within areas of high water quality using the Ecosystem Approach to Aquaculture (EAA) and Marine Spatial Planning (MSP), which increases food security […]

NOAA Estimates Nitrogen Removal Rates from Shellfish Farms around the World

Excessive nutrient input into estuarine and coastal environments, also known as eutrophication, can lead to algal blooms, oxygen depletion, fish kills, and a general loss of key habitats. New research from NOAA supports using shellfish aquaculture for nutrient removal and eutrophication reduction. To include shellfish aquaculture as part of a comprehensive approach to nutrient management, scientists measured […]

Does Oyster Aquaculture Affect Nitrogen Loss From Sediments?

Off-bottom oyster aquaculture (Crassostrea virginica) is currently being investigated for possible effects on nutrient processes of surrounding sediments by  a Virginia Sea Grant Research Fellow, Abby Lunstrum, under the guidance of an NCCOS mentor. The research assesses whether, and to what extent, biodeposition from this type of aquaculture operations stimulates loss of nitrogen from the […]

Oyster Gardening Improves Water Quality, Featured by National Geographic

The innovative “Maryland Grows Oysters” program, designed to use oyster restoration for improvement of water quality in Chesapeake Bay, was featured in a National Geographic video released on October 9. The project uses cages first produced by inmates at the Hagerstown Correctional Facility and then filled with baby oysters (or spat), which are attached to docks at volunteer study locations within the Chesapeake […]

Fish Farming Improvements Reduce Environmental Impacts of Aquaculture

Advances in fish farming technology and management practices significantly decreased the environmental footprint and increased economic performance of aquaculture in the United States in the last forty years. Marine aquaculture in the United States represents an opportunity to provide healthy, domestic seafood, create jobs, and contribute to coastal economies, likely supplying most of the expected […]
