21,000 FTEs employed in the Norwegian fishing fleet
The total contribution to wealth creation from the Norwegian marine fishing fleet in 2021 was NOK 32.8 billion, including ripple effects.
Fishing and fisheries

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.
A vessel that ‘hand-picks’ its catch from the seabed
The Arctic Pearl is setting course for the Barents Sea in search of the shellfish delicacy Iceland scallop. It is the first and only vessel of its kind, crammed with new technology that may herald the start of a new era in bottom fishing.
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.
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.
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?
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.
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.
Following sea trout minute by minute
Sea trout populations have declined sharply. Researchers have studied the life of sea trout by means of acoustic telemetry tags and listening stations. Now they know more about what we need to do to protect the sea trout population.
Six years into the ice — and beyond
The Arctic’s once impenetrable ice cap is melting away, with profound consequences for everything from ocean circulation patterns to fish numbers and diversity. The Nansen Legacy Project, including NTNU biologists, chemists and engineers, is working to better understand what these changes mean for the Barents Sea and the Arctic Basin
Is frozen cod just as good as fresh?
Yes. As long as it is handled properly, new research reveals.
Most of a fish is discarded
Every year 340,000 tonnes of usable whitefish by-product are discarded into the sea. But the fisheries industry has now identified ways of halting this practice.
Researching the dark side of microplastics
Minute particles of plastic, called microplastics, are everywhere. An international research team is now about to investigate how toxic microplastics are to marine animals such as plankton, crabs and fish, and to find out if such plastics accumulate in the food chain.
Help for fishing vessels to locate their catch
Big Data means that professional fishermen will soon be getting their own decision-making tool. It will tell them where fish shoals are located, and how their vessels can be operated as economically as possible.
Awash in trash at the top of the world
Every year, an estimated 8 million metric tons of plastic waste blows, falls or flows into the world’s oceans. Earlier this autumn, participants in the annual Svalbard Course plucked up 512 kg of the stuff from just one beach in two hours.
Machine vision for catch quality assurance
Robots equipped with machine vision enable us to classify catches on board vessels with high levels of accuracy – saving fishing crews time and money.
The secret life of the sea trout
Armed with special acoustic tags, a team of researchers is following 50 individual fish for as long as seven months to learn more about their life – and death — in Norwegian fjords.
Building a hybrid fishing boat
It isn’t just car manufacturers that are looking into hybrid energy systems. A Norwegian boat builder is now aiming to become the world’s first supplier of environmentally friendly fishing vessels.
