Fridtjof Nansen travelled the polar regions as both an explorer and a scientist. Ten research institutions followed in Nansen’s footsteps in a collaborative investigation of the Barents Sea. Their 6-year effort has now been documented in a new book.
Only five percent of small fishing boats chill their catch on board, despite the fact that temperature plays a crucial role when it comes to quality and shelf life.
Bristle worms and soldier fly larvae can grow on aquaculture sludge and become protein-rich feed for fish and livestock. But toxic substances can infiltrate the loop. Now scientists have learned more about which substances we need to keep an eye on.
The world needs more of the valuable nutrients found in fish viscera, liver and roe. Yet, much of this raw material is being thrown back into the sea. There are good reasons to stop this wasteful practice.
Underwater robots, combined with simple instruments from 100 years ago, are helping researchers unlock the secrets of microscopic marine organisms called plankton.
Here’s how Norway can limit the loss of an all-important substance, phosphorus.
More than a million tonnes of fish residues can rescue the food and cosmetic industries from raw materials shortages – and create new jobs. The key factors here are oils rich in omega-3, collagen and gelatin.
Seaweed and kelp, or macroalgae, are used in many products, and may become an even more important resource in the future. Artificial intelligence can help us avoid overusing this valuable resource.
Greenland’s glaciers are melting and the surrounding seawater is getting warmer. How are arctic char coping with climate change? Scientists are in the process of figuring it out.
In the sea, fish feed on species lower in the food chain. Can these same species form the basis of a new feed industry supplying the fish farming sector?
The transition to a greener, renewable economy will require large amounts of minerals, and society has to get them from somewhere. Norwegian politicians have reached an agreement approving deep sea mining, in a proposal that has reaped both cheers and frustration from scientists and activists alike. Here’s what our scientists think.
Fish faeces and residual feed recovered from salmon hatcheries may soon become a sustainable product. The salmon farming sector will be crying out for a solution to the forecast ‘feed squeeze’.
We should use all parts of whole farmed salmon and keep more of the residuals here in Norway. Researchers say this will help protect the environment while ensuring salmon welfare.
Bacteria in raw seafood can make you sick. Seafood can also spread bacteria that are resistant to antibiotics.
Bacteria discharged to the oceans in sewage and wastewater thrive on the biofilms that form on plastic waste. This may be leading to the somewhat unanticipated problem of antimicrobial resistance.
“A sense of community between generations will be key to ensuring sustainable coastal communities. The importance of children’s learning through work is underestimated,” says Professor Anne Trine Kjørholt.
Most of our planet is underwater – and steadily more will be underwater in the years to come. What do we really know about the underwater world?
The total contribution to wealth creation from the Norwegian marine fishing fleet in 2021 was NOK 32.8 billion, including ripple effects.
What are people’s attitudes towards food, sustainability, new foods and food additives? Researchers have found some answers.
Today we think of cusk as a bycatch species of little or no value. But our test panel came to quite a different conclusion.
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.
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.
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.
If artificial light shines into the Arctic Ocean during the polar night, does it matter? A new paper in Communications Biology says the answer to this is a strong yes.
