By cutting out a particular gene, scientists can make farmed salmon sterile. This prevents escaped fish from spawning with wild salmon. Now scientists have also worked out how to produce sufficient quantities of sterile salmon for commercial production.

The CRIMAC centre wants the echo sounder itself to be able to distinguish between herring, mackerel, shrimps and gas emissions. Now scientists have completed their first expedition to learn the “dialect” of herring.

A new study shows how young eels find their way from their birthplace in the Sargasso Sea to Norwegian fjords and river mouths. 

Harbour porpoises that get entangled in gillnets die slowly. But there may be a simple solution.

Researchers have reviewed almost everything: from surveys, trawling methods and sampling, to calculations and management strategies. They have come up with new methods and tools. In five years, the REDUS project has made the fish stock advice of the Institute of Marine Research (IMR) more reliable.

At fish markets in Ghana, fish is sold either smoked, salted or sun-dried. A new study has now shown that this fish is rich in many important micronutrients, which came as a surprise to researchers.

With warmer seas and less sea ice around Svalbard, fishing boats and expedition cruise ships move northwards and extend their operational season and areal coverage. The implications of the increase in human activity for the vulnerable ecosystem in this region can be severe.

In a new study, researchers have for the first time measured omega-3 levels in pregnant women from all over Norway. They found that pregnant women who took dietary supplements had the highest omega-3 levels in their bodies.

Sardines, anchovies, horse mackerel and axillary seabream are popular along the African coast. A new study shows that these species contain lots of important minerals and vitamins, particularly if the fish are eaten whole.

DNA test reveals female salmon has spawned an incredible five times in the River Etneelva.

Herring is whimsical. One year it can appear in large numbers near the coast in winter, return to the same area several winters in a row, and then suddenly disappear.

New study shows even very low concentrations of crude oil impair haddock larvae’s ability to swim. Negative impact was found at a third of what was previously believed to impact the larvae.

Here’s how you make it!

The small stones from the fish’s head provide new information about cod have been affected by fishing, population dynamics and climate change. 

The otolith is the fish equivalent of a black box. One warehouse in Bergen contains several million otoliths dating from 1906 to the present day.

When researchers simulated anti-sea lice treatments, the plume of chemicals that can be dangerous to the larvae typically spread out 5 to 15 kilometres as it diluted.

When asked about which industry is the most sustainable, 29 percent of Norwegians answer fishing and fish farming. Only half as many answer oil and gas.

The kayak can find fish in the blind spot of larger research ships.

New technology makes it possible to follow life at depths of up to 1,500 metres live over the Internet.

Creates new opportunities for both the fishing and technology industries. 

24 selected small boats are scanning the Norwegian coast for the world's largest tuna. The Institute of Marine Research (IMR) obtains unique information from this “citizen science” project.

“Facial recognition” of fish is one way that artificial intelligence is already used in marine research. But there are many other possible applications.

As clean energy expands, demand for metals and rare earth elements is growing along with it. Developing the wind turbines, solar panels and batteries that will power our low-carbon future requires cobalt, nickel, zinc, copper, silver, gold, lithium and more.

It is found all over the world, and it is abundant along the Norwegian coast, but you’ve probably never heard of it. Now researchers are studying how aquaculture affects maerl beds in northern Norway.

Six vessels will cover ten times Norway's area in search of the mackerel. This year you can follow them live on the map.

Lobsters in protected areas have bigger claws than lobsters in areas where they are fished, according to a new study. 

Hardangerfjorden has developed a clear green tint, prominent enought to be observed from space. The reason is microscopic.

New analysis of old samples shows that eels in Norway get twice as old as previously thought. 

Last spring Atlantic salmon were tagged with satellite tags in Southern Norway. Now they have phoned home. 

The water entering the Barents Sea is not as cooled down as it used to. This has a large effect of the climate in the area and may lead to fish and other marine life migrating.
