Nofima is researching the best ways of using snow crabs as more and more of the species are being caught in the Barents Sea by both Norwegian and Russian vessels.
Traditionally, snow crabs have been one of the most important products from Alaska, but with up to 4,000 tonnes of the species being landed in Norway in the past year, Nofima says it’s time to get to know the cold-loving crab.
“The snow crab is an important species now and will continue to be so in the future,” said Kjell Midling, head of the Nofima centre. “It is therefore natural for us to investigate how we can keep them alive in order to achieve the best possible quality and price.”
Nofima’s aim is to investigate shelf life and quality. Work is also focused on using the leftover raw material from snow crabs to ensure sustainable use of the resource. In addition, the scientists are working with commercial companies on the development of new bait and crab pot technology.
Many of the snow crab’s biological characteristics are still unknown. Little has been documented about its physiology, what it can tolerate and how it lives. In future studies with living crabs, Nofima will also look at what water temperature they need and how closely together they can live and thrive.
The market for snow crabs is global and prices are good, says Nofima, and it’s the flesh in the snow crab’s legs that is eaten, but scientists say it’s possible that the rest of the crab may be of value.
“Because it’s a cold water species, it is very interesting to look for marine enzymes and bioactive components that are adapted to the cold. We will investigate this and see how such enzymes might be used commercially,” added Ragnhild Whitaker, who is heading the research.
In previous research projects, Nofima’s scientists have found bioactive components in king crab shells and in prawns that are now used as ingredients in a range of products, including medicines and health foods.
The snow crab is similar in appearance to the king crab, but lives in deeper water, where it thrives in the lower temperatures.
Nofima, which has extensive knowledge of the king crab, says it’s looking forward to gaining similar knowledge about snow crabs.
