Snow crab in the Barents Sea – a new prey for Northeast Arctic cod
The snow crab ( Chionoecetes opilio) is a newly established species in the Barents Sea, increasing in both distribution and abundance in recent years. In this Arcto-Boreal sea, they encountered the most abundant Atlantic cod ( Gadus morhua) stock. What happens from here?

Cod-Haddock 2-1 in Barents Sea
In the Boreal-Arctic seas, the two most abundant gadoid fish are the Atlantic cod ( Gadus morhua) and the haddock ( Melanogrammus aeglefinus). Both tend to respond to climate warming by an abundance increase and a change of distribution. Are these changes affecting how they are interacting? Statistical analysis using a state-space threshold model of acoustic and trawl survey data on cod and haddock abundance indicates that the interaction is changing with sea temperature: the cod negatively affecting the haddock when sea temperature is over 4 °C.
