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.
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.
Vegetable farmers will soon be helping to reduce greenhouse gas emissions and environmental pollution while at the same time boosting our self-sufficiency.
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’.
We should use all parts of whole farmed salmon and keep more of the residuals here in Norway. Researchers say this will help protect the environment while ensuring salmon welfare.
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.
