Southern California Coastal Managers Provide Guidance for Sustainable Offshore Aquaculture Development

NOAA and partners recently convened a two-day workshop to develop a roadmap for sustainable aquaculture development in the coastal waters off Southern California. Participants developed consensus on primary environmental concerns, reviewed the regulatory framework for coastal aquaculture development, and created a coastal manager working group to guide the permitting process. The aquaculture industry in southern […]

NOAA Supports Development of Offshore Aquaculture in Southern California

California state and federal managers are using NOAA information and tools to develop environmentally sustainable offshore finfish aquaculture in the Southern California Bight—an industry with the potential to generate $1 billion annually. NOAA’s assistance with coastal planning, models of environmental interactions and effects, and siting is helping the state address concerns over environmental impacts that have […]

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 […]
