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.
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.
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.
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.
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?
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.
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.
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.
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.
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’.
The aquaculture sector can now download a set of guidelines containing 25 ideas about the circular use of plastics.
Nineteenth-century Norwegian technology helped bring large whale populations to the brink of extinction. Can 21st-century technology help save them?
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.
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.
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.
“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.
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.
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.
The total contribution to wealth creation from the Norwegian marine fishing fleet in 2021 was NOK 32.8 billion, including ripple effects.
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.
