Parasites affect salmon in several ways
When salmon ingest parasites, the parasite may not be the only factor that determines the impact on the health of the fish.

Observing Arctic marine life — from the seabed to space
NTNU researchers from AMOS, the Centre for Autonomous Marine Operations and Systems, used small satellites and subsea robots — and everything in between — to study marine life in Svalbard’s Kongsfjorden in a first-ever experiment in May.
Plastic waste is a resource that doesn’t have to end up in the oceans
Using non-recyclable plastic waste as an alternative to coal may prevent huge volumes of plastic from being discarded into the oceans – and will also reduce CO2 emissions. This is the conclusion of a recently completed pilot project headed by SINTEF in Vietnam.
A cushy lab life has its evolutionary costs — when it comes to fish, that is
An animal’s ability to adapt to its environment is clearly key to its survival, but does that ability come at a physiological cost? A clever experiment with laboratory zebrafish and their wild relatives suggests it does.
Scientists call for cap on production to end plastic pollution
Capping production of new plastics will help cut their release to the environment — and brings other benefits, from boosting the value of plastics to helping tackle climate change.
The Detectives: Hunting toxic chemicals in the Arctic
What researchers are learning about the fate of chemicals in the Arctic, and how what they’re learning is changing international law and providing life-saving advice.
Plastics leach toxins
Plastic contains thousands of chemicals. Until now, we haven’t known if these leach into the environment to any great extent. Now we know that they do.
A natural gem is being destroyed by plastic
Mausund and the Froan Nature Reserve are located in an archipelago far out to sea along the Trøndelag county coast, but they are not exactly pristine. About 25 per cent of the soil in the area contains plastic.
Norway has been given a floating ocean laboratory
The OceanLab will contribute to research on underwater robotics, aquaculture, autonomous shipping and environmental research.
How do dolphins learn to live along the coast?
Ocean-dwelling dolphins have repeatedly adapted to life in coastal areas throughout history.
What is nature worth?
Climate change is not the greatest threat to the diversity of species on Earth. The main problem is that animal and plant habitats are disappearing.
Rapid action can help prevent the worst consequences of global warming
A new report from the Intergovernmental Panel on Climate Change (IPCC) describes with unnerving detail just what can happen if nations fail to limit greenhouse gas emissions. But rapid international action will keep the worst consequences at bay, the panel said.
Artificial intelligence makes it easier to study wild fish at salmon farm sites
New technologies, including artificial intelligence, allow us to study salmon behaviour and their living environment in large-scale commercial sea cages.
The stag hunt – and why a circular economy is so difficult
The will is there. The technology is too. So why is only 2.4 per cent of the Norwegian economy circular?
A robotic microplankton sniffer dog
The microscopic, free-floating algae called phytoplankton — and the tiny zooplankton that eat them — are notoriously difficult to count. Researchers need to know how a warming climate will affect them both. A new kind of smart, lightweight autonomous underwater vehicle (LAUV) can help.
Toxic fluorocarbons – not just in ski waxes
The toxic pollutants in your ski wax basically never disappear. A Norwegian lake and the area around several Norwegian airports are full of them, and so is your body.
Researchers found an underwater landfill while looking for chemical discharges from mobiles and electronic devices
Research scientists in Norway recently set out on a scientific cruise in the Trondheim fjord to collect water samples and specimens of marine species. What they stumbled over was quite different from what they were looking for.
New technology will identify sources of plastic in the ocean
Plastic trash gets cleaned up along our beaches. But it’s also important to find out where the plastic comes from. A Norwegian app will soon be able to do this.
Building trust in robots to measure, monitor, and regulate the ocean
A new partnership between the Centre for the 4th Industrial Revolution Ocean and the Norwegian University of Science and Technology (NTNU) has been established to establish trust in ocean data collected from autonomous underwater vehicles.
Shedding light — on the polar night
The polar night is dark — if you’re a person. But not if you’re a krill or a seabird or a fish. In the first episode of NTNU’s new English-language podcast, 63 Degrees North, learn how researchers discovered that there’s more than enough light in the polar night for the tiny creatures who live there.
Found traces of antidepressants and painkillers in crustaceans on Svalbard
A team of researchers studying our footprint in the Arctic has taken samples of marine animals and wastewater linked to tourism. Their findings have revealed surprising levels of pharmaceutical drugs.
Smart site selection can make hydropower greener
Even though new hydropower dam developments are intended to provide green energy, they can drown areas that are rich in plant and animal species. But this kind of collateral damage can be limited by strategic site selection, a new study shows.
Reveals hungry salmon with sound waves
The feed cost represents about 50 percent of the costs of farming salmon. But how do we know if the salmon is hungry or still full? Researchers have rethought to find answers. The result is less wastage and pollution – and enough food for the salmon.
Global warming is faster than evolution
If global warming happens too quickly, not all species will be able to adapt in time.
