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.
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 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.
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.
An entirely new fish farm design, which looks more like an elongated offshore oil platform than a traditional aquaculture facility, may soon be installed in Norwegian waters.
When China wants to exploit its hydropower resources, they can ask Norwegian researchers for advice. It is now possible for hydropower companies in China to read the handbook for environmental design of regulated rivers in their own language.
Professor Jon Olaf Olaussen says that increasing the aquaculture industry to five times its current production now is a crazy idea. He is calling for reducing one of Norway’s largest industries.
The best weapon in the battle against salmon lice in the Norwegian aquaculture industry has proved to be the use of what are called “cleaner fish”, fish that eat salmon lice. But these fish often die during breeding. Now, researchers have found a way to help the young fish survive.
Hundreds of tonnes of food are thrown away in Norway every year. Supercooling could keep more fish out of the trash, and even extend the grilling season.
