The cod larvae swam towards the noise. 

Climate researchers from almost 70 countries will meet in Bergen. They have lots to talk about.

It requires special effort to get to know the “cold water barracuda”. Our leading angling expert reveals the secrets of the Norwegian hake.

Researchers have discovered the ideal length of day for smolts.

Whale faeces contain large quantities of nutrients that are important to the ocean ecosystem, according to a new study.

In April, leading climate scientists will gather in Bergen to discuss how climate change is affecting the ocean.

According to marine scientists, it fails to take into account important gaps in our knowledge about the natural environment and bottom currents in the impact assessment area.

Join us in a tour through our labs and meet our scientists.

When excessive quantities of mackerel are crowded tightly together in the net, the fish experience poor welfare.

“As scientists, we have a responsibility not just to find problems, but also to solve them”, says Nils Gunnar Kvamstø, the CEO of the Institute of Marine Research.

Across two spawning seasons, researchers have exposed Atlantic cod to powerful blasts from airguns during spawning and tracked the behaviour of the fish. The results have now been published.

Before surveying the area, scientists expected to find large areas of untouched seabed – and the odd trawl mark left by fishing boats. What they actually found was nothing like that.

They combined off-the-shelf products with a new, dynamic strategy: moving the salmon down – and up – away from the lice.

Four students were nevertheless able to complete their master’s projects in Norway. They have now returned to their home country with lots of valuable skills.

This autumn there has been a big increase in the number of string jellyfish along the coast. This colonial jellyfish can reach lengths of up to 30 metres and it can be fatal to farmed fish.

One was eaten by a whale, another caught by a local fisherman called Håkon, and three returned to the same spot they were tagged a year ago.

A new study reveals that the variety of Ichthyophonus found by researchers in mackerel is a new species, and not the one typically found in herring.

Seafood safety in a changing environment is the focus of the recent special issue of Environmental Pollution, a joint effort by IMR and UN-IAEA. Two out of eleven papers were written by IMR scientists.

Low capelin growth and lack of survey coverage on Russian side makes the advice lower than last year.

For the first time, IMR scientists have successfully tagged a porbeagle with a satellite tag. Now researchers can learn more about what the great white shark's "little brother" does in Norwegian waters.

“Good news in times of climate change.”

Haddock larvae swam more slowly after being exposed in the laboratory to magnetic fields similar to those created by undersea cables connecting offshore wind farms.

The first bilateral quota recommendation for cod, haddock and deepwater redfish in the Barents Sea is now ready. 

That is 20 percent lower than the previous year, and lowest since 2009.

Researchers have digitised shrimp landings data going almost right back to when the Norwegian shrimp fishery started around the turn of the 20th century.

Parts of the Lofoten–Vesterålen Ocean Observatory are operational and collecting new scientific data again after more than a year of downtime.

Data from the autopsy of the walrus could provide valuable information about the animal, for example about its diet.

Since 2019, IMR scientists have tagged cod in Western Norway only to “bother” them with noise during the spawning season. The aim is to be able to give better advice on seismic surveys.

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