Sardines from the cold waters off South Africa’s Atlantic coast are attracted to cold water upwelling in the Indian Ocean. When the upwelling ends, they are trapped in water that is too warm for them.
Researchers used an old theory on vibrating plane wings to study how fish swim so well. They were able to double the swimming efficiency of their robotic fish over a range of speeds.
Rivers are among the most embattled ecosystems on Earth. Researchers are testing a new, inexpensive way to study river health by using eDNA to count the species that rivers harbor.
Goby fish and coral rely on each other to survive. But new research found gobies are declining under climate change, dealing a double blow to Australia’s reefs.
When conditions are just right in some parts of the Indian Ocean, a type of bacteria will multiply and start to glow. Satellites are helping scientists study these milky seas for the first time.
Fish fins are extremely flexible yet also strong. A special segmented fin design is the key to this useful combination of properties and could inspire new morphing materials.
The giant sea bass fishery collapsed long ago in the US, but that didn’t mean the species was endangered. New research shows these iconic fish have been thriving south of the border.
Traditional ecological and cultural wisdom was embraced and valued, enhancing Western scientific knowledge of a beautiful, fragile marine area.
The growing frequency of climate extremes affected human health and caused wide-scale damages to the ecosystems that people depend upon, including agriculture, fisheries and freshwater.
The WTO is set to wrap up negotiations on harmful fisheries subsidies This could help rebuild the oceans’ fish stocks, and support the communities that rely on them.
Pescatarians might frustrate purist vegetarians, but the issues surrounding fish are quite different to meat.
Chemicals in drugs can be excreted unchanged, infiltrating waterways via sewage and effluent.
Warm-blooded fish can swim 1.6 times faster than their cold-blooded relatives.
Determining the age of fish has been historically difficult, primarily involving lethal methods. A new DNA test solves this problem.
New data from tropical and subtropical regions suggests insects are declining thanks to dammed rivers
Kenya needs to address spending inefficiencies to attain the goals outlined in the budget.
The lives of one in ten of Earth’s species are connected to lakes and their tributaries.
Seabirds journey vast distances across the Earth’s seascapes to find food and to breed. This means their biology, particularly their breeding success, can reveal what’s happening in our oceans.
In the design of marine protected areas, new research suggests that it might be better to start small in order to gain local trust and support that leads to larger long-term benefits.
New findings suggest the loss of fertility at high temperatures is a major threat to the survival of some species.
