The exploitation of marine species worsens when the fish stock is shared by countries as opposed to when it is contained within a single exclusive economic zone.

Growing research shows that fish produce sounds that other creatures listen to to find food and avoid becoming prey. A new database compiles research on these fish sounds.
The Biden administration is moving to revive mercury limits for coal-fired power plants. A scientist explains mercury’s health risks and the role power plants play.

For the opening of the One Ocean Summit in Brest from February 9 to 11, 2022, France’s marine research institute looks at promising avenues of research to protect the planet’s largest ecosystem.
Because of their social nature and the fact that they share 70 per cent of their DNA with humans, zebrafish make ideal test subjects.

Growing interest in psychedelics has spurred new research decades after hallucinogenics were tested in Saskatchewan in the 1950s. And an unassuming common fish is proving a useful test subject.
As climate change worsens, their findings highlight the importance of conserving natural river flows to enable freshwater species to respond and adapt.

Salmon migrate thousands of miles from inland streams to the ocean and back. The newly enacted infrastructure bill includes funding to help salmon and other wild species on their way.
Some lumpfish are friendly, others not so much.

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 have been building robotic fish for years, but the performance has never approached the efficiency of real fish.

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.
Environmental DNA is a promising tool for tracking species in freshwater ecosystems like Oregon’s Elkhorn Creek.

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.
