Sustainability and animal welfare concern young people the most
What are people’s attitudes towards food, sustainability, new foods and food additives? Researchers have found some answers.

Researchers gave an identity to the world’s first fully electric high-speed ferry
Scientists have now found out how to optimise the functional and aesthetic character of the world’s first fully electric high-speed ferry. The aim is to persuade passengers to opt for fossil-free transport.
Crowding-induced stress gives mackerel the blues
Researchers have succeeded in showing that mackerel turn blue when under stress. This new knowledge will better enable our fisheries to safeguard fish welfare and will optimise catch quality into the bargain.
Could cusk fish be the new cod?
Today we think of cusk as a bycatch species of little or no value. But our test panel came to quite a different conclusion.
In the future, Norwegian salmon can be fed with locally-sourced ragworms
Researchers had the crazy idea of feeding ragworms with locally-cultivated seaweeds. The results were as gold-edged as the worms themselves – a high-quality, locally-sourced and sustainable feed for farmed salmon.
“Pamela” makes studying the ocean easy and affordable
NTNU biology and cybernetics researchers have built a robot that allows them to sample everything from microplastic to salmon lice densities.
Testing lice traps on the Hardanger coast
Researchers at NINA, the Norwegian Institute for Nature Research, and NTNU have developed a new method for monitoring salmon lice larvae along the coast. The lice trap is now being tested in the Hardangerfjord.
Norwegian rivers need to be better protected
When hydroelectric power plants suddenly switch off the water, we risk killing fish fry and other living organisms in rivers. The regulations need to change, say scientists and anglers.
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.
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.
Norway has been given a floating ocean laboratory
The OceanLab will contribute to research on underwater robotics, aquaculture, autonomous shipping and environmental research.
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.
Combating marine waste and ghost fishing with new materials
Ghost fishing and plastic waste from the fisheries industry is becoming a major environmental problem. Can we address the issue by using degradable plastics? Scientists at a new research centre are aiming to find the answers and develop the systems we need.
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.
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.
Fish farms moving onshore
Land-based fish farming offers many benefits to both the fish and the environment. In traditional offshore farms, the fish are vulnerable to sea lice infestation and infectious diseases. Modern land-based aquaculture systems are able to offer local fish products in landlocked countries.
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.
Meet the aquaculture industry’s new maintenance bot
This ROV can fully operate on its own, and follow along with fish’s behaviour and health with its Argus eyes – all while keeping a safe distance. It even inspects the technical standard of the enclosure while it’s at it. Say hi to Mr. CageReporter.
Are discarded mobile phones and electronic waste polluting our seas?
The Norwegian research organisation SINTEF will investigate whether rare earth element minerals contribute to pollution in costal areas. Research scientists from Norway, Denmark and Germany are taking part in the project.
Why aren’t sea trout thriving anymore?
Sea trout numbers are declining in Norway and scientists don’t know why. They have studied the trout in two rivers in northern Norway’s Nordland county. Soon, sea trout along the entire Norwegian coast will be investigated.
Cleaner fish being sacrificed in the fight against salmon lice
Research shows that even fish farmers have doubts as to whether using cleaner fish is an effective delousing method. “Fish farmers tell us that they want a ban on the use of certain species. They’re also very critical of wild-caught cleaner fish being transported,” says researcher Kristine Størkersen. She is one of the scientists who have been helping the Norwegian Food Safety Authority gain an overview of the situation.
Robo-turtles in fish farms reduce fish stress
Robotic turtles used for surveillance could help prevent escapes from salmon farms. The “turtle robots” are paving the way for a technology that improves monitoring inside sea cages.
