Shark depredation, where a shark partially or completely consumes a fish before a fisherman can get it out of the water, causes a range of negative biological and economic impacts. Scientists have found a novel way to address this issue using a citizen-science approach that includes surveys, videos, forensics and social media.
Industrial fleets from countries around the world have been increasingly fishing in African waters, but with climate change and increasing pollution threatening Africa’s fish stocks, there is a growing concern of the sustainability of these marine fisheries if they continue to be exploited by foreign countries.
Charles Darwin, the British naturalist who championed the theory of evolution, noted that corals form far-reaching structures, largely made of limestone, that surround tropical islands. He didn’t know how they performed this feat. Now, Rutgers scientists have shown that coral structures consist of a biomineral containing a highly organized organic mix of proteins that resembles what is in our bones. Their study, published in the Journal of the Royal Society Interface, shows for the first time that several proteins are organized spatially – a process that’s critical to forming a rock-hard coral skeleton.
Overfishing likely did not cause the Atlantic cod, an iconic species, to evolve genetically and mature earlier, according to a study led by Rutgers University and the University of Oslo – the first of its kind – with major implications for ocean conservation.
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.
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.
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.
After a nuclear war, wild-catch marine fisheries will not offset the loss of food grown on land, especially if widespread overfishing continues, according to a Rutgers co-authored study. But effective pre-war fisheries management would greatly boost the oceans’ potential contribution of protein and nutrients during a global food emergency, according to the study in the journal Proceedings of the National Academy of Sciences. The study for the first time explored the effects of nuclear war on wild-catch marine fisheries.
For the first time, a research team has obtained high resolution sedimentary core samples from Lake Tanganyika. The samples show that high frequency variability in climate can lead to major disruptions in how the lake’s food web functions. The changes could put millions of people at risk who rely on the lake for food security. The team says the findings are a critical building block toward research-informed policymaking in the Lake Tanganyika region.
A new study investigating the links between coastal communities and coral reefs in Kenya and Madagascar has found that access to education and markets can help mitigate acute vulnerabilities for communities struggling with poverty and reliant on ecosystems degraded by overfishing.
Current marine protected areas in the Southern Ocean need to be at least doubled to adequately safeguard the biodiversity of the Antarctic, according to a new CU Boulder study.
To address plastic pollution plaguing the world’s seas and waterways, Cornell University chemists have developed a new polymer that can degrade by ultraviolet radiation, according to research published in the Journal of the American Chemical Society.
Climate change could threaten the survival and development of common whelk – a type of sea snail – in the mid-Atlantic region, according to a study led by scientists at Rutgers University–New Brunswick. The common, or waved, whelk (Buccinum undatum) is an important commercial species that has been harvested for decades in Europe and Canada for bait and human consumption. Its habitat within the mid-Atlantic region is one of the Earth’s fastest warming marine areas and annual fluctuations in the bottom temperature are among the most extreme on the planet due to unique oceanographic conditions.
Researchers reporting in ACS’ Environmental Science & Technology have linked microplastics in China’s Beibu Gulf with heavy fishing activities.
New Brunswick, N.J. (Jan. 13, 2020) – Rutgers University–New Brunswick Professor Olaf P. Jensen is available for interviews on new marine fisheries management research to be published in the journal Proceedings of the National Academy of Sciences. The study is the most comprehensive…
New Brunswick, N.J. (Oct. 16, 2019) – Rutgers University environmental law expert Cymie R. Payne is available to comment on a proposed international treaty aimed at conserving high seas biodiversity. The treaty, which is under negotiations at the United Nations,…
New Brunswick, N.J. (Sept. 17, 2019) – High levels of fecal bacteria have often been found at six new water sampling sites in the lower Raritan River since May, according to a Rutgers-coordinated monitoring program that included more than 20…
