Clean water eliminated effects of discharged drugs in fish
The discharge of pharmaceutical drugs is a major problem around the world, but a new study of the freshwater fish burbot shows that there is hope.
Fish and aquaculture

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.
Six billion NOK for new Ocean Space Laboratories
Three new fjord laboratories, one in Trondheim, one in Hitra/Frøya and one in Ålesund, along with two test basins in Trondheim are planned as part of the project.
Entrepreneurs aim to end ghostfishing
A small device, developed in Norway, will now be used in the battle against environmentally-unfriendly ghost fishing caused by lost or forgotten fishing gear.
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.
Nine things to know about microplastics
Picking up a plastic bag from the beach makes a bigger difference than you might imagine.
Researchers are hunting microplastic with jellyfish
In the innovative EU project GoJelly, researchers are working to solve the microplastic challenge by using products from nature itself.
Herring larvae could benefit from an acidifying ocean
Excess CO2 in the atmosphere is making the oceans more acidic. Some studies show that’s bad news for fish, including commercially important species. But not all fish respond the same way.
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.
Plastic ends up on the ocean floor
According to a new research report, most plastic fragments end up on the ocean floor.
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.
Secrets of the sea raised from the depths
The mysteries below the ocean’s surface have triggered human exploration and imagination for centuries. New marine robotics now make it possible to explore what goes on in the ocean depths.
Shedding light on zooplankton in the dark
We know that tiny marine creatures in the Arctic respond to weak light from the Moon or the northern lights during the polar night. Now researchers have learned that artificial light from research vessels can also have a negative effect.
Norwegian scientists will teach Europe to make snow
Trondheim: Norwegian researchers believe that it will be possible to make environmentally-friendly snow at above-zero temperatures. Now they have the backing of Europe and the skiing industry in their bid to save the sport from climate change.
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.
Algae can outcompete soya and become big business
Establishment of the Norwegian Centre for Plankton Technology has yet to be completed, but there has nevertheless been high levels of interest from both industry and research.
Tomorrow’s fish farms will be unmanned
Robotics technology is making inroads into the aquaculture sector, making it possible to regulate facilities from onshore.
Climate change, ocean diversity and women in science
Science has made great strides since Svante Arrhenius, the Swedish Nobel Laureate who in 1896 first determined that carbon dioxide from human activity could warm the planet. The same progress hasn’t been made in increasing the number of women in the sciences.
