Down by the Bay: Project Supports Safe Oyster Production

Oyster production is a key contributor to the local food economy in New Jersey’s Delaware Bay. The “merroir” of the Bay’s tide flats gives oysters their unique and desired taste. However, recent increases in illnesses caused by raw oyster consumption threaten the Bay’s oyster farming future. The culprit is Vibrio parahaemolyticus (Vp), a bacterium commonly […]

NJ farm evaluates oyster seed nursery practices

Oyster farming is increasing in the Northeast and is a top contributor of our region’s $161 million in annual aquaculture sales. However, a major challenge to the continued growth of this shellfish crop is availability of oyster seed. Hatchery and nursery capacity for seed production is limited, and often the demand for oyster seed exceeds […]

UMaine student explores temperature tolerances of kelp

As a sea vegetable, kelp may help Northeast acquaculturists diversify their businesses and contribute to this multibillion-dollar industry. Charlotte Quigley, a PhD student at the University of Maine, used her Northeast SARE Graduate Student grant to study Alaria esculenta, a kelp that is of interest to U.S. growers due to its market potential, nutritious and […]

Minimizing the risks of Vibrio bacteria in farm-raised oysters grown in intertidal elements of the Delaware Bay

New Jersey’s oyster farms are concentrated on the extensive intertidal sand flats of the lower Delaware Bay where they are exposed twice daily during low tide. Previous studies from the Pacific Northwest indicate that intertidal exposure accelerates the proliferation of Vibrios, increasing the risk to human health.
