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 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.

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. 

Sevastopol i Bergen

Sixty years of Norwegian–Russian marine research cooperation


The Soviet research vessel Sevastopol arrived in Bergen on 16 February 1958. On board were eight scholars who were to resume the marine research cooperation that Norway and Russia had established before the Russian Revolution of 1917. Half a year later, Norwegian marine scientists returned the favour by visiting Murmansk.
