How to reduce plastic in the seafood industry
Norway exports salmon fillets in large quantities, the quality of which must be preserved during transportation. Nofima researchers are investigating the possibility of preserving quality and food safety while reducing the use of plastics.
Norway! Keep up with vegetarian trends!
A recent analysis shows that Norway still has untapped potential when it comes to developing its own plant-based products using local ingredients.
The long road from Arctic science to international law
The second meeting of the Parties to the Minamata Convention on Mercury takes place this week in Switzerland. The road to the international convention took almost 15 years and is significantly influenced by Arctic research and Norwegian efforts.
Bringing fish heads and bones back to the dinner table
New project will convert residual by-products into high-quality, functional ingredients, using efficient and sustainable processing methods.
This approach not only binds CO2, but also improves the soil
If 4,000 Norwegian farms and nurseries produced biochar and mixed it with the soil, we could halve CO2 emissions from the agricultural sector. This entirely natural approach also produces more robust and healthy plants.
DNA analyses reveal secrets about the Pacific oyster
Is oyster larvae drift across the Skagerrak the cause of wild oysters great increase? New DNA analyses provide insight into the origin of the first wild Norwegian sea oyster populations.
EU wants more organic salmon in stores
Organic salmon can be difficult to find in European shops, and people do not know much about organic fish in general. Now, new research highlights the need for updating EU regulations.
How environmental and dietary changes affect farmed fish
Aquaculture diet has become increasingly plant based. In addition, the industry faces environmental changes. Recent findings in salmonids when the two challenges are combined, give cause for concern.
Microplastics in the earth: A reason to worry?
While the focus to date has been on microplastics in the ocean, microplastics in soils have largely been overlooked. Researchers are concerned about the lack of knowledge regarding potential consequences of microplastics in agricultural landscapes.
Farmed salmon with lice prefer the deep
At night, salmon with heavy lice infestations swim deeper than the rest of the shoal. For the first time, this shows that salmon might have a natural behaviour that prevents new sea lice infestations.
Breeding gluttons in the battle against salmon lice
Scientists have started to breed fish which have a special liking for consuming salmon lice. The preference for salmon lice seems to be a genetic trait.
Salmon will have to make do with less omega-3
Omega-3 is in short supply and must be distributed wisely. Farmed salmon is one of the omega-3 lovers who now have less omega-3 in their diet than before. The question scientists are asking is how little marine omega-3 farmed salmon can cope with.
Salmon puberty gene discovered
Researchers have discovered that a specific gene plays a very important role in determining whether a salmon returns to spawn as a large or small salmon. They identified the gene and revealed its secret.
Kon Tiki 2 sets sail
Two balsa rafts have sailed from Lima, Peru for the Easter Island. In six weeks the expedition will return after a trip of more than 5000 nautical miles. The rafts are equipped for full scale oceanographic research and the first attempt in our time to show how ancient mariners sailed the Pacifics.
The mackerel is out of shape
In recent years, mackerel stocks have been thriving, both in terms of their numbers and distribution. But the individual mackerel are not doing so well. They are growing more slowly and have become thinner, probably due to tough competition for food within the population.
Salmon - Norway's most important livestock
Over the course of just a few years, salmon farming has become one of Norway's most important industries. Yet we know little about the salmon. New research raises the fish to its rightful place as one of Norway’s most important livestock.
Chinese boycott of Norwegian salmon industry unsuccessful
China's boycott of Norwegian salmon has affected Chinese consumers more than Norwegian salmon exporters. Importers are finding workarounds, with the Chinese receiving poorer quality and more expensive Norwegian salmon.
North Europeans resisted farming
North Europeans resisted adaption of farming and herding when these practices arrived in Europe about 8,000 years ago, according to a new study conducted by a team including Archaeology Professor Francesco d’Errico at the University of Bergen.
Frozen versus fresh vegetables
Stored fresh vegetables have lower vitamin C content than frozen. Research scientists have examined and compared nutrients in frozen and fresh vegetables.
Developing climate-smart agriculture
How should India and other countries adapt their agricultural practices to a changing climate? Researchers explain how they go about when developing new rice growing technologies.
New weapons in the battle against salmon lice
The best weapon in the battle against salmon lice in the Norwegian aquaculture industry has proved to be the use of what are called “cleaner fish”, fish that eat salmon lice. But these fish often die during breeding. Now, researchers have found a way to help the young fish survive.
Video: Salmon lice on sea trout and Atlantic salmon
Salmon lice have always been a natural parasite on wild salmonids. However, during the last years the infestation of salmon lice has increased on wild salmonids causing negative consequences – and especially for sea trout.
Mutated salmon louse DNA spread throughout the North Atlantic in 11 years or less
A recent study has demonstrated that genetic changes giving the salmon louse partial resistance towards one of the most commonly used delousing chemicals in marine aquaculture (emamectin benzoate/Slice) have spread to salmon lice in the entire North Atlantic in a maximum of just 11 years.
More and more cows are catching colds
Respiratory infections in cattle pose a large and growing problem in Norway, resulting in impaired animal welfare and the increasing use of antibiotics. Simple measure to prevent infection can put a stop to the cold virus.
Premiere for intensive production of Atlantic bluefin tuna
Up until now, it has been impossible to produce high-quality feed for the early stages of one of the world’s most valuable fish species. Researchers believe that they have managed to crack the code.
Social innovations may hold the key to future food security
UN Special Rapporteur believes in developing new ways to produce and distribute food. “Today's food system is not reducing hunger, despite increasing levels of production, but has instead contributed to inequality in rural areas,” he says.
Cross-infection of foot rot between sheep and cattle
Foot rot is a serious and contagious hoof disease in sheep. New research has now revealed that cattle can also be carriers, even though they themselves are not seriously affected by the disease.
