Bristle worms and soldier fly larvae can grow on aquaculture sludge and become protein-rich feed for fish and livestock. But toxic substances can infiltrate the loop. Now scientists have learned more about which substances we need to keep an eye on.
Using well-known offshore technology from the oil industry, along with a completely new idea, the founders of Farmocean-subsea want to create equipment for aquaculture at sea. Way out at sea.
The world needs more of the valuable nutrients found in fish viscera, liver and roe. Yet, much of this raw material is being thrown back into the sea. There are good reasons to stop this wasteful practice.
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.
Fish welfare: Using a digital eye and artificial intelligence, scientists have found a way of monitoring the breathing of salmon. The method can reveal whether or not the fish are stressed.
Underwater robots, combined with simple instruments from 100 years ago, are helping researchers unlock the secrets of microscopic marine organisms called plankton.
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.
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.
Here’s how Norway can limit the loss of an all-important substance, phosphorus.
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.
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.
Researchers have recently found out how to use algae to convert ammonia and nitrates into a nutrient-rich fertiliser or fish feed ingredients.
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.
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.
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.
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.
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.
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.
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?
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.
