Blueye is an underwater drone that got its start at NTNU. The drone can be used for serious purposes – such as when it mapped damage to the Norwegian frigate Helge Ingstad – or for entertainment, such as showing cruise passengers the underwater landscape.
The electronic “sensor” fish measures the physical factors that affect farmed fish during delousing. The results may lead to welfare improvements in salmon farm cages.
The oceans are teeming with ever-increasing numbers of jellyfish. These squishy sea creatures can ruin fishing and discourage tourists. But one research group wants to turn this nuisance into pay dirt.
The amount of omega-3 fatty acids in farmed salmon is dropping. But a reasonable and affordable solution may make salmon even healthier to eat.
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.
The aquaculture industry typically selects salmon with the right genes for breeding to provide the freshest and biggest fish. A new method has the potential to produce better results.
Aquaculture used to be a secondary income source for Norwegians. Now it’s become big business. Occupational safety has made steady advances, but some areas clearly still need to improve.
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.
The condition of the water in salmon hatcheries can tell us a great deal about when and why outbreaks of disease occur. Now, SINTEF researchers are about to expose the water’s secrets, both to prevent suffering in fish and to save the aquaculture industry a great deal of money.
Robotics technology is making inroads into the aquaculture sector, making it possible to regulate facilities from onshore.
The Japanese eat one in ten of the world’s fish, and 80 per cent of the planet’s prized —and critically threatened — Bluefin tuna. Tuna aquaculture pioneered at Kindai University in Japan offers hope for both fish lovers and the fish.
