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

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

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

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

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

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

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.

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.

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

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

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

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

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.

Scientists call for ocean-based action to tackle the climate crisis.

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

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

Until October 13, you can follow our videostream live from the seafloor off the Skagerrak coast in southern Norway.

The key to its success is fresh water from the Matre mountains.

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. 

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

Humpback whales are once again abundant in their summer grazing grounds in the western Southern Ocean. 

First published in Norwegian in Nordnorsk debatt: On Wednesday 18 August, «Johan Hjort» left Kirkenes to start the first leg of the 17th annual ecosystem research cruise (eco cruise) in the Barents Sea.

Fish as a source of important micronutrients deserves increased attention in discussions on food and nutrition policy.

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.
