Herring school in fish tank.

Spring-spawning herring were tricked into spawning in autumn

Researchers find more mackerel have Kudoa parasites


The Kudoa parasite gives the mackerel’s flesh a soft, jelly-like consistency after it is dead.

Researchers identify the halibut’s sex gene


Results from new genetic research could contribute to the further development of halibut as a farmed fish species.

Supergenes protect cod against environmental changes


Researchers have found that Atlantic cod possess a set of “supergenes” that enable them to quickly adapt to environmental changes.

Could fish larvae be disturbed by offshore wind farms?


A unique project at IMR aims to shed light on the impact of offshore wind farms on the vulnerable early life stages of fish.

Fish farmers can influence the traits of fish through the feed


Behaviour and environmental conditions affect how genes are expressed. New research demonstrates how epigenetics may be highly relevant to the aquaculture industry.

Confirmation that sea trout are heavily affected by salmon lice


In Western Norway, over half of all sea trout are infested with so many salmon lice that you would expect it to seriously harm their health.

A trawl with blue whiting

An opening at the bottom can prevent the trawl bag from bursting


Several hundred tonnes of blue whiting per trawl haul are fished, and accidents can occur. The trawl bag can simply burst because of the catch sizes.

Computer learns to identify fish species in trawl images


Scientists have trained an artificially intelligent system to automatically count and recognize the species of fish that are photographed in the trawl under water.

Ocean economy suffers as marine heatwaves are ramping up


Marine heatwaves are becoming more frequent and intense due to climate change. This has wide-ranging impacts for ocean-human interactions, researchers find.

Kabel gjenfunnet Foto HI

Ocean Observatory: The missing cable has been found


On Thursday afternoon, the research vessel G.O. Sars found cable that was missing from Lofoten-Vesterålen sea observatory (LoVe).


Ocean Observatory temporarily out of service


The Lofoten–Vesterålen Ocean Observatory (LoVe) is currently out of service. This is due to extensive damage to the outer circuit of the observatory, and it will take time for the full system to return to normal operations.

bluefin tuna from 2021

Satellite-tagged bluefin tuna swam 15,000 kilometres in a year


…and ended up at the same spot, at the same time where the scientists had tagged it the previous year.

After being trapped in Norway by the pandemic, Dr. Fridtjof Nansen is once again heading out into the world


The research vessel has been in Norway since March 2020. Now it is returning to Africa – with five first-time crew on board.

Successful transfer of an ocean model to China


The Yellow Sea Model which is based on the Institute of Marine Research's coastal current model is now producing important results for Chinese aquaculture in the Yellow Sea.

Lower mercury concentrations in Greenland halibut


Reduced emissions to air and water have contributed to a significant decrease in Greenland halibut mercury concentrations from the Norwegian Sea.

Going global: Researchers aim to collect and organize data on plastic pollution from around the world


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.

The scientists explain: why all the fuss about iodine?


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

IMR explains: Mercury


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.

New methods for feed control in a circular economy


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.
