A day in the life of a jellyfish hunter

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.

Raising better salmon

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.

Improving occupational safety in aquaculture

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.

Keeping ocean currents from spreading disease in farmed salmon

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.

Secrets of the sea raised from the depths

The mysteries below the ocean’s surface have triggered human exploration and imagination for centuries. New marine robotics now make it possible to explore what goes on in the ocean depths.

Shedding light on zooplankton in the dark

We know that tiny marine creatures in the Arctic respond to weak light from the Moon or the northern lights during the polar night. Now researchers have learned that artificial light from research vessels can also have a negative effect.

Norwegian scientists will teach Europe to make snow

Trondheim: Norwegian researchers believe that it will be possible to make environmentally-friendly snow at above-zero temperatures. Now they have the backing of Europe and the skiing industry in their bid to save the sport from climate change.

A “health centre” for juvenile salmon

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.

Climate change, ocean diversity and women in science

Science has made great strides since Svante Arrhenius, the Swedish Nobel Laureate who in 1896 first determined that carbon dioxide from human activity could warm the planet. The same progress hasn’t been made in increasing the number of women in the sciences.

Most of a fish is discarded

Every year 340,000 tonnes of usable whitefish by-product are discarded into the sea. But the fisheries industry has now identified ways of halting this practice.

Researching the dark side of microplastics

Minute particles of plastic, called microplastics, are everywhere. An international research team is now about to investigate how toxic microplastics are to marine animals such as plankton, crabs and fish, and to find out if such plastics accumulate in the food chain.

Help for fishing vessels to locate their catch

Big Data means that professional fishermen will soon be getting their own decision-making tool. It will tell them where fish shoals are located, and how their vessels can be operated as economically as possible.
