How can we save wild salmon from extinction, and at the same time ensure farmed salmon a life free from lice and other suffering? Research uncovers critical challenges related to management, fish welfare, monitoring and control in the aquaculture industry.
Researchers have been studying algae that eat kelp instead of making their own sugar. The findings open up new ways of making all kinds of useful things out of kelp.
It can take up to 200 years for damaged marine environments to fully recover by just stopping the destruction and leaving the ecosystems to themselves. That is why we must implement active restoration interventions.
When animals evolve to tolerate higher temperatures, those evolutionary changes might have other negative effects. Or maybe not.
It could take up to 200 years for our degraded ocean habitats to fully recover if we just leave them alone. So, we must intervene. The good news is that it works.
Norwegian seabirds are struggling. Svalbard seabirds have mercury levels above the threshold for deleterious effects on reproduction, researchers have found.
These man-made toxic substances are often referred to as ‘forever chemicals’. There are thousands of different variants, and researchers are finding more and more of them.
Ropes and fishing gear used in the fisheries and aquaculture industries are a major source of microplastics in the ocean and littering along the coastline. A multidisciplinary international research team has now drawn up a plan that will help to reduce pollution.
Underwater robots, combined with simple instruments from 100 years ago, are helping researchers unlock the secrets of microscopic marine organisms called plankton.
There are millions of species on Earth that we still know nothing about. Researchers call these species ‘biological dark matter’, but new methods can provide us with a better overview more quickly.
Out of sight, out of mind? Far from it! Urine, faeces and toilet paper are the only things you should ever flush down the toilet. Anything else has a negative impact on marine life.
Imagine if everyone were to agree to do everything they can to help the planet. Right now. What sort of state would we and the planet be in in 2050? And what would we have to do?
Here’s how Norway can limit the loss of an all-important substance, phosphorus.
More than a million tonnes of fish residues can rescue the food and cosmetic industries from raw materials shortages – and create new jobs. The key factors here are oils rich in omega-3, collagen and gelatin.
Norway leads the world when it comes to the use of robots in the aquaculture sector. But how do these robots actually impact on the fish? Cyberneticist Eleni Kelasidi is surprised by just how much.
Research is revealing that a cod-like fish called ‘cusk’ may soon be making a big splash on Norwegian dinner plates. But you will have to search long and hard to find it on sale today.
It is currently prohibited to provide animals with feed derived from the same animals’ own ‘value chain’. But this legislation is not based on science.
For the first time, researchers have investigated how ropes and fishing lines are handled by the Norwegian commercial fishing industry. The fishing fleet loses almost 400 tonnes of rope in Norwegian waters every year.
Shooting sound waves through water can remove dissolved gas that results from hydropower production in rivers. This gas can harm fish. Researchers are now ready to test techniques to reduce the risk in real hydropower plants.
Greenland’s glaciers are melting and the surrounding seawater is getting warmer. How are arctic char coping with climate change? Scientists are in the process of figuring it out.
In the sea, fish feed on species lower in the food chain. Can these same species form the basis of a new feed industry supplying the fish farming sector?
Norway’s law on mining seabed minerals is too unclear, the knowledge base too flimsy, and the Storting’s White Paper on seabed mining does not hold water.
The transition to a greener, renewable economy will require large amounts of minerals, and society has to get them from somewhere. Norwegian politicians have reached an agreement approving deep sea mining, in a proposal that has reaped both cheers and frustration from scientists and activists alike. Here’s what our scientists think.
Norway already exports large amounts of valuable alginate, but new research findings can make this industry even larger and more sustainable.
