Plastic pollution readily crosses boundaries between countries and ecosystems. Research and monitoring also requires a holistic approach and a global perspective, argues initiator Michael Bank.

Nutritionists often say that young women in Norway consume too little iodine. Why? And what has it got to do with the sea?

New evidence that humpbacks sing outside of their tropical breeding grounds. 

In our new series "Seafood for land crabs", you will get to know your dinner better! We take a closer look at what useful and important nutrients you should get through your diet, how they work and why you need them. We also look at the less pleasant substances, the ones that we should not get too much of.  

Insect farming for fish-feed production offers interesting opportunities in aquaculture, but it also raises new challenges for food and feed safety testing. Researchers have now developed and tested new methods for detecting and tracing prohibited ingredients in insect meal.

New marine resources such as mesopelagic fish may play a larger role in future food systems. Researchers are now studying what this could mean for our health.

IMR researchers have found a wreck off Bodø that they assume must be DS Malmberget. After 108 years, we may be close to solving the mystery of this ship, which disappeared in a storm with 43 people on board. 

Bottom dwelling animal species may become extinct before scientists are able to discover them. That is one of the conclusions of the UN’s Second World Ocean Assessment.

Historical and contemporary samples of Norwegian and Canadian cod show that the fish’s genome has remained stable over time.

For thousands of years, seafarers have lived in fear of dangerous monsters living in the ocean. We’ll guide you through their treacherous waters.

This is good news for both fishers and fish stocks.

… and why this creates a challenge for land-based fish farming.

Five new vessels, four of which are autonomous, will be an integral part of the Institute of Marine Research's long-term cruise strategy. 

One two-thousandth of the “salmon dose” was lethal to the krill.

19 researchers from the Institute of Marine Research are included in a recent ranking of the world's top scientists.

Insects, mussels and bristle worms are some of the candidates being considered by the aquaculture industry and marine scientists, as they search for new, sustainable raw ingredients.

There are at least two reasons why fish could not have been the source of the virus.

The corkwing wrasse has a fascinating behaviour. Now, researchers have mapped the sounds made by this colourful fish. 

New research found little evidence that herring and mackerel were responsible for salmon decline. 

Select the right species of fish, find a suitable location sheltered from tropical storms and, hey presto, you can start farming fish in Cuba.

Seafood can play a key role in meeting the UN Sustainable Development Goal of ending hunger by 2030. ⁠⁠⁠”That makes it really important to emphasise the role of seafood and to include it in food strategies”, says research scientist Marian Kjellevold.

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.
