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.
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.
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.
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.
Researchers surprised at levels of toxicity in standard plastic products
Tonnes of waste from standard plastic products have been uncontrollably released into the world’s oceans, where they gradually break down. But how harmful is this plastic to living organisms, and what is it in these plastics that is so damaging?
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.
Making seaweed cultivation into a major industry
Seaweeds can be used to improve soils and for the biological capture and storage of carbon. They can serve as feed for livestock and as a food and health supplement for humans. And that’s just for starters. A new research project is aiming to help upgrade current cultivation systems to an industrial scale.
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.
Norway needs a ‘salmon feed revolution’
The issue of salmon feed has become a bottleneck, hindering the growth and sustainability of the Norwegian aquaculture sector. In the future, insect meal, bristle worms and bacteria that consume CO2 may become essential components of a farmed salmon’s diet.
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.
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.
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.
Locking CO2 captured from seaweed in biocoal
Seaweeds cultivated in the sea off the coast of Trøndelag, Norway will be converted into biocoal and used to improve agricultural land. A new method for carbon capture and storage is now being trialled by Norwegian researchers.
The healthiest crisps on the planet
Researchers have now found out how to stop the formation of harmful acrylamides when deep-frying potatoes to make crisps.
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.
Digital twins offer us access to new knowledge
Now, in 2023, there are almost no limits to how much data we can collect and store away. But what can we use all this information for, and how do we find out what the data can tell us?
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.
Deep learning may help to prevent salmon escapes in rough seas
Artificial intelligence can be of great benefit underwater and SINTEF, in collaboration with the research centre SFI Exposed, is developing systems that will help to boost fish farm safety and security under harsh sea conditions.
