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.
We need to know more, and teach more people, about aquaculture so we can use the ocean’s resources to the greatest extent possible while protecting the environment.
Currents in the ocean and fjords spread viruses that are killing large numbers of farmed salmon. Where should fish farms be built? And should they all be in use at the same time? Researchers now know more about how to limit the virus problem.
Robot vision has given us self-steering drones, and may also help keep an eye on salmon in fish pens and make sure that our children are healthy.
Fish farming is the largest source of phosphorus emissions in Norway, generating about 9,000 tonnes a year. Finding ways to reuse the waste from the fish farming industry could cut consumption of this important and increasingly scarce resource.
With the help of new 3-D technology, you can dive underwater and swim with farmed salmon.
