Bacteria discharged to the oceans in sewage and wastewater thrive on the biofilms that form on plastic waste. This may be leading to the somewhat unanticipated problem of antimicrobial resistance.
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.
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.
Most of our planet is underwater – and steadily more will be underwater in the years to come. What do we really know about the underwater world?
Bacteria-free fish fry put researchers on the track of how they could make fish more disease resistant.
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?
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.
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.
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.
What are people’s attitudes towards food, sustainability, new foods and food additives? Researchers have found some answers.
Scientists have now found out how to optimise the functional and aesthetic character of the world’s first fully electric high-speed ferry. The aim is to persuade passengers to opt for fossil-free transport.
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.
Today we think of cusk as a bycatch species of little or no value. But our test panel came to quite a different conclusion.
Researchers had the crazy idea of feeding ragworms with locally-cultivated seaweeds. The results were as gold-edged as the worms themselves – a high-quality, locally-sourced and sustainable feed for farmed salmon.
NTNU biology and cybernetics researchers have built a robot that allows them to sample everything from microplastic to salmon lice densities.
Researchers at NINA, the Norwegian Institute for Nature Research, and NTNU have developed a new method for monitoring salmon lice larvae along the coast. The lice trap is now being tested in the Hardangerfjord.
When hydroelectric power plants suddenly switch off the water, we risk killing fish fry and other living organisms in rivers. The regulations need to change, say scientists and anglers.
When salmon ingest parasites, the parasite may not be the only factor that determines the impact on the health of the fish.
