The walrus"Freya": – People should keep their distance


That's the clear advice from our marine mammal scientist.

IMR to lead large EU project on kelp and mussel farming within offshore wind farms


The project receives funding of 8,2 million EUR over the course of four years.


Satellite tagging 8-metre sharks


The researchers were able to tag three basking sharks in a single weekend. Read more here.


"Freya" the walrus may be an environmentalist


The pacific oyster is an invasive species that has fixed its grip along the coast of Southern Norway. It might also be the main diet of "Freya" the walrus, currently eating her way in the Oslofjord.

Artificial intelligence has been taught to "read" salmon scales


Determining the age of salmon from their scales is a task for trained experts. Now artificial intelligence may give them a hand.

Scientists from Norway and Sudan work together to preserve marine ecosystems


For more than a decade, IMR researchers have been working closely with colleagues from partner institutions in Sudan with a particular focus on small scale fisheries.

Herring school in fish tank.

Spring-spawning herring were tricked into spawning in autumn


When researchers manipulated the hours of daylight in an experimental setup, they got herring to spawn during the "wrong" time of year.

New study on potential impacts of wind industry on marine life in the North Sea.


Researchers find more mackerel have Kudoa parasites


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

Three large halibut.

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.

Person inserting acoustic tracker into fish.

Big Data reveals the secret lives of animals


New and improved technology allows researchers to track the movements of fish and other animals from second to second.

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.

Small fish marked with paper slips on a table as part of a trial.

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.


Nils Gunnar Kvamstø is the new CEO at IMR


He is excited and motivated for his new role at one of the biggest marine research institutes in Europe.
