Researchers work to promote phosphorus recovery and recycling
Here’s how Norway can limit the loss of an all-important substance, phosphorus.

Bacteria could make salmon healthier
Bacteria-free fish fry put researchers on the track of how they could make fish more disease resistant.
Breathing new life into waste industrial marine plastics
The fisheries and aquaculture sectors are major users of plastics. A research project has recently been launched to investigate how these plastics can be recycled and made into new products.
“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.
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.
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?
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.
More people and fewer wild fish lead to an omega-3 supply gap
Omega-3 fatty acids are essential components of healthy diets for both humans and fish. The dramatic increase in fish farming worldwide has boosted the demand for omega-3 fatty acids so much that today’s supply can’t meet demand. Reducing waste and finding new sources can help.
Tourism, aquaculture and offshore accidents with Blueye
Blueye is an underwater drone that got its start at NTNU. The drone can be used for serious purposes – such as when it mapped damage to the Norwegian frigate Helge Ingstad – or for entertainment, such as showing cruise passengers the underwater landscape.
Better fish welfare using “sensor” fish
The electronic “sensor” fish measures the physical factors that affect farmed fish during delousing. The results may lead to welfare improvements in salmon farm cages.
A day in the life of a jellyfish hunter
The oceans are teeming with ever-increasing numbers of jellyfish. These squishy sea creatures can ruin fishing and discourage tourists. But one research group wants to turn this nuisance into pay dirt.
Cheap plant oil can give us healthier salmon
The amount of omega-3 fatty acids in farmed salmon is dropping. But a reasonable and affordable solution may make salmon even healthier to eat.
Plans for a 385-metre fish farm facility in the open sea
An entirely new fish farm design, which looks more like an elongated offshore oil platform than a traditional aquaculture facility, may soon be installed in Norwegian waters.
Teaching the next generation of fish farmers for the aquaculture industry
We need to know more, and teach more people, about aquaculture so we can use the ocean’s resources to the greatest extent possible while protecting the environment.
Raising better salmon
The aquaculture industry typically selects salmon with the right genes for breeding to provide the freshest and biggest fish. A new method has the potential to produce better results.
Improving occupational safety in aquaculture
Aquaculture used to be a secondary income source for Norwegians. Now it’s become big business. Occupational safety has made steady advances, but some areas clearly still need to improve.
Keeping ocean currents from spreading disease in farmed salmon
Currents in the ocean and fjords spread viruses that are killing large numbers of farmed salmon. Where should fish farms be built? And should they all be in use at the same time? Researchers now know more about how to limit the virus problem.
Is frozen cod just as good as fresh?
Yes. As long as it is handled properly, new research reveals.
A “health centre” for juvenile salmon
The condition of the water in salmon hatcheries can tell us a great deal about when and why outbreaks of disease occur. Now, SINTEF researchers are about to expose the water’s secrets, both to prevent suffering in fish and to save the aquaculture industry a great deal of money.
Tomorrow’s fish farms will be unmanned
Robotics technology is making inroads into the aquaculture sector, making it possible to regulate facilities from onshore.
Putting Bluefin tuna back on the menu — by farming them
The Japanese eat one in ten of the world’s fish, and 80 per cent of the planet’s prized —and critically threatened — Bluefin tuna. Tuna aquaculture pioneered at Kindai University in Japan offers hope for both fish lovers and the fish.
