Robots collaborate on remote sampling of zooplankton
In the first week of summer, a dynamic team of robots, researchers, students, and engineers in SFI Harvest and AUR-Lab embarked on a mission to sample zooplankton off the coast of Mausund, Norway.

Here you can watch a sea cucumber sensation!
After three years of waiting it has finally happened. Researchers have succeeded in getting a red sea cucumber, widely regarded as the world’s most expensive seafood, to spawn in the lab.
Researchers work to promote phosphorus recovery and recycling
Here’s how Norway can limit the loss of an all-important substance, phosphorus.
Autonomous ships are on the horizon: Is AI ready to take command?
Artificial Intelligence (AI) is well suited to observe and understand what is going on around a ship. However, before we can allow AI to make safety-critical decisions, we need to be aware of how certain the decisions are, as well as why AI makes them.
Fish residues can compensate for raw materials shortages and improve our health into the bargain
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.
Nutrient-rich fertiliser from toxic ammonia
Researchers have recently found out how to use algae to convert ammonia and nitrates into a nutrient-rich fertiliser or fish feed ingredients.
Artificial intelligence makes smarter use of seaweed and kelp
Seaweed and kelp, or macroalgae, are used in many products, and may become an even more important resource in the future. Artificial intelligence can help us avoid overusing this valuable resource.
Fishers working from small vessels are at the greatest risk
Friday 1 March another Norwegian fisherman was drowned while working. He became the 156th Norwegian working in the industry to lose his life since the new millennium. A safety researcher at SINTEF says that this only goes to underline the message delivered in a report recently published by her team.
Researchers surprised by penned fish responses to robots
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.
Precautionary fundamentalism is threatening Norwegian food production
If the Norwegian government rejects the majority opinion of the Gene Technology Committee, it will miss a long overdue opportunity to boost food safety, improve animal welfare and promote more eco-friendly pesticides.
A ‘new’ fish may soon be finding its way onto fresh food counters
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.
Is it safe to feed farmed salmon with bristle worms raised on fish excrement?
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.
If we can’t untangle this mess, Norway’s blue industry will never be green
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.
Is there a new deep-sea fishery on the horizon?
Well, some researchers believe this is possible. Species living at depths between 200 and 1000 metres may be very valuable. However, harvesting them isn’t as easy as it might sound because, when taken on board, valuable catches change rapidly from pure gold to ashes.
Ultrasound can save fish in hydropower rivers
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.
Climate change in Greenland could cause trouble for arctic char
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.
Copepods – tiny creatures that can help reduce the need for soya imports
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 will be the first in the world to approve seabed mining. Is it a good idea?
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.
Researchers want to create a forecasting system for oxygen concentrations in sea water
Farmed fish suffer if there is too little oxygen in the water. A system that can display oxygen concentrations may make it easier to supply this essential gas if the water becomes oxygen-poor.
Six out of ten are worried that their work is affecting their health
The 1,283 workers in the aquaculture sector who have responded to a recent HSE survey are not anxious without good reason. Sixty-two percent have experienced ‘near misses’ in the last two years. However, there is another threat that is making them even more worried.
This tiny gadget can tell us all about how a farmed salmon is doing
Sick and injured farmed salmon are a problem, but researchers have recently developed an implant that uses sensors to gather information about the welfare of individual fish.
Fish excrement – a superfood for plants
Vegetable farmers will soon be helping to reduce greenhouse gas emissions and environmental pollution while at the same time boosting our self-sufficiency.
Early whaling eradicated species from local waters
Several whale species disappeared from Europe long before whaling became a major industry. Two of the most common species are no longer found here, and one of them is almost extinct.
Sludge from salmon hatcheries will become a sought-after resource
Fish faeces and residual feed recovered from salmon hatcheries may soon become a sustainable product. The salmon farming sector will be crying out for a solution to the forecast ‘feed squeeze’.
