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.
Fishing and fisheries

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.
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.
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?
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.
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’.
New guidelines for a greener seafood sector
The aquaculture sector can now download a set of guidelines containing 25 ideas about the circular use of plastics.
Listening to Leviathans
Nineteenth-century Norwegian technology helped bring large whale populations to the brink of extinction. Can 21st-century technology help save them?
Small snail looking to be big business
Researchers have succeeded in nurturing a small snail called periwinkles in the laboratory for the very first time and are hoping that this French delicacy might be the launch pad for a new, Norwegian aquaculture business.
Teaching the world how hydropower development can safeguard fish populations
SINTEF researcher Marcell Szabo-Meszaros is the man behind the international study ‘Hydropower and Fish – a Roadmap for Best Practice Management’, which offers guidelines on fish population protection in rivers to companies carrying out hydropower developments.
Learning to trace salmon lice
Is it only farmed fish that are responsible for spreading salmon lice larvae? Or is it also possible that wild salmon can infect farmed fish? This is what researchers will be trying to find out.
Professor wants to involve children in work
“A sense of community between generations will be key to ensuring sustainable coastal communities. The importance of children’s learning through work is underestimated,” says Professor Anne Trine Kjørholt.
The aquaculture sector is aiming at better plastic recycling
There is enormous potential in the aquaculture sector to generate circular economy initiatives when it comes to its use of plastics. But can these be made commercially viable? Researchers believe that they can.
Fish farming: this new vessel concept will assist open ocean aquaculture
The aim is to extract the most efficient performance from all the various vessels utilised by the aquaculture sector at facilities exposed to rough seas and strong currents. Researchers have been looking into all aspects of this issue.
21,000 FTEs employed in the Norwegian fishing fleet
The total contribution to wealth creation from the Norwegian marine fishing fleet in 2021 was NOK 32.8 billion, including ripple effects.
Breathing new life into waste industrial marine plastics
The fisheries and aquaculture sectors are major users of plastics. A research project has recently been launched to investigate how these plastics can be recycled and made into new products.
A vessel that ‘hand-picks’ its catch from the seabed
The Arctic Pearl is setting course for the Barents Sea in search of the shellfish delicacy Iceland scallop. It is the first and only vessel of its kind, crammed with new technology that may herald the start of a new era in bottom fishing.
Crowding-induced stress gives mackerel the blues
Researchers have succeeded in showing that mackerel turn blue when under stress. This new knowledge will better enable our fisheries to safeguard fish welfare and will optimise catch quality into the bargain.
Could cusk fish be the new cod?
Today we think of cusk as a bycatch species of little or no value. But our test panel came to quite a different conclusion.
