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-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

“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.

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.
