UrduLittle is known about the ecological relationship of Vibrio bacteria with Sargassum. Evidence also is sparse as to whether vibrios colonizing plastic marine debris and Sargassum could potentially infect humans. As summer kicks off and efforts are underway to find solutions to repurpose Sargassum, could these substrates pose a triple threat to public health? Results of a study representing the first Vibrio spp. genome assembled from plastic finds Vibrio pathogens have the unique ability to “stick” to microplastics, harboring potent opportunistic pathogens.

There’s something fishy about flake sold in South Australia
It is a popular takeaway choice at fish and chip shops, but new research has revealed threatened species of shark are being sold as flake at some outlets across South Australia. The University of Adelaide study is the first of its kind to examine flake fillets sold at South Australian fish and chip shops.
During Virginia Oyster month in November–and all year long–Virginia Tech seafood researchers help oyster farmers adapt to water quality issues
Over the last three decades, Maryland and Virginia have suffered more than $4 billion in cumulative annual losses because of the decline of industries related to oyster harvesting. Likewise, harvests have fallen to less than one percent of historic levels. As Virginia…
What to Call Seafood Made from Fish Cells
Food companies, regulators, marketers, journalists and others should use the terms “cell-based” or “cell-cultured” when labeling and talking about seafood products made from the cells of fish or shellfish, according to a new Rutgers study in the Journal of Food Science.
Fishes Contribute Roughly 1.65 Billion Tons of Carbon in Feces and Other Matter Annually
Scientists have little understanding of the role fishes play in the global carbon cycle linked to climate change, but a Rutgers-led study found that carbon in feces, respiration and other excretions from fishes – roughly 1.65 billion tons annually – make up about 16 percent of the total carbon that sinks below the ocean’s upper layers.
Nuclear War Could Trigger Big El Niño and Decrease Seafood
A nuclear war could trigger an unprecedented El Niño-like warming episode in the equatorial Pacific Ocean, slashing algal populations by 40 percent and likely lowering the fish catch, according to a Rutgers-led study. The research, published in the journal Communications Earth & Environment, shows that turning to the oceans for food if land-based farming fails after a nuclear war is unlikely to be a successful strategy – at least in the equatorial Pacific.
How to Identify Heat-Stressed Corals
Researchers have found a novel way to identify heat-stressed corals, which could help scientists pinpoint the coral species that need protection from warming ocean waters linked to climate change, according to a Rutgers-led study.
COVID-19 Pandemic had Big Impact on Commercial Fishing in Northeast
With restaurants and supply chains disrupted due to the global coronavirus pandemic, two-fifths of commercial fishermen surveyed from Maine through North Carolina did not go fishing earlier this year, according to a Rutgers study that also documented their resilience and adaptation. Of those who kept fishing, nearly all reported a decline in income compared with previous years, according to the survey of 258 fishers in the Northeast published in the journal PLOS ONE.
Planning Ahead Protects Fish and Fisheries
Conservation of fish and other marine life migrating from warming ocean waters will be more effective and also protect commercial fisheries if plans are made now to cope with climate change, according to a Rutgers-led study in the journal Science Advances.
U.S. Seafood Industry Flounders Due to COVID-19
The pandemic is putting a hurt on the seafood industry, finds the largest study of COVID on U.S. fisheries, which suggests that American fishmongers may flounder – or go belly up – without more government aid.
-Monthly fresh seafood exports declined up to 43%
-Monthly imports fell up to 37%
-Catches dropped 40% some months.
Over the first six months of 2020:
-Total U.S. seafood exports are down 20%
-Imports are down 6%
-Further losses are likely as restrictions increase to address COVID-19.
Rutgers Expert Available to Discuss Risk Perception in COVID-19 Era
New Brunswick, N.J. (Oct. 26, 2020) – Rutgers University–New Brunswick Professor William Hallman is available for interviews on the science of risk perception and its practical implications in the COVID-19 era – a time of fear and anxiety among millions of…
Rutgers-Led Project Will Buy 76,000 Oysters From Farmers Struggling During COVID-19 Pandemic
New Brunswick, N.J. (Sept. 10, 2020) – A Rutgers-led project will buy 76,000 oysters from New Jersey oyster farmers who are struggling to sell the shellfish following the shutdown of restaurants and indoor dining as a result of the COVID-19…
“Wrong-Way” Migrations Stop Shellfish From Escaping Ocean Warming
Ocean warming is paradoxically driving bottom-dwelling invertebrates – including sea scallops, blue mussels, surfclams and quahogs that are valuable to the shellfish industry – into warmer waters and threatening their survival, a Rutgers-led study shows.
In a new study published in the journal Nature Climate Change, researchers identify a cause for the “wrong-way” species migrations: warming-induced changes to their spawning times, resulting in the earlier release of larvae that would then be pushed into warmer waters by ocean currents.
Seafood Products Made From Cells Should be Labeled Cell-Based
Companies seeking to commercialize seafood products made from the cells of fish or shellfish should use the term “cell-based” on product labels, according to a Rutgers study – the first of its kind – in the Journal of Food Science. Both the U.S. Food and Drug Administration and U.S. Department of Agriculture require food products to have a “common or usual name” on their labels so consumers can make informed choices about what they’re purchasing.
$5.7 million to fight global hunger awarded by Mississippi State-based Fish Innovation Lab
The Feed the Future Innovation Lab for Fish at Mississippi State University is awarding $5.7 million in grants to develop innovative approaches for helping solve hunger affecting more than 800 million people worldwide.
Oyster Farming and Shorebirds Likely Can Coexist
Oyster farming as currently practiced along the Delaware Bayshore does not significantly impact four shorebirds, including the federally threatened red knot, which migrates thousands of miles from Chile annually, according to a Rutgers-led study. The findings, published in the journal Ecosphere, likely apply to other areas around the country including the West Coast and Gulf Coast, where oyster aquaculture is expanding, according to Rutgers experts who say the study can play a key role in identifying and resolving potential conflict between the oyster aquaculture industry and red knot conservation groups.
Oysters and Clams Can be Farmed Together
Eastern oysters and three species of clams can be farmed together and flourish, potentially boosting profits of shellfish growers, according to a Rutgers University–New Brunswick study. Though diverse groups of species often outperform single-species groups, most bivalve farms in the United States and around the world grow their crops as monocultures, notes the study in the journal Marine Ecology Progress Series.
Global Cooling After Nuclear War Would Harm Ocean Life
A nuclear war that cooled Earth could worsen the impact of ocean acidification on corals, clams, oysters and other marine life with shells or skeletons, according to the first study of its kind.
Rutgers Shellfish Expert Available to Discuss East Coast Oyster Breeding Project
New Brunswick, N.J. (Oct. 15, 2019) – Rutgers University–New Brunswick shellfish geneticist Ximing Guo is available to comment on a five-year Rutgers-led consortium project to breed better, more disease-resistant East Coast oysters. Improved oyster broodstock will then be made available…
