Crowding-induced stress gives mackerel the blues

Researchers have succeeded in showing that mackerel turn blue when under stress. This new knowledge will better enable our fisheries to safeguard fish welfare and will optimise catch quality into the bargain.

Coastal marshlands are the place between land and sea

An ‘unknown’ ecosystem that is good news for the climate

At the boundary between the land and sea, there exists an ecosystem that has been overlooked by Norwegians for so long that it was only recently given an official name. But studies are revealing that it has some very desirable properties.

Long-houl shipping at sea

Ammonia – the key to making long-haul shipping green

Relatively simple adaptation could make the cargo ships of the future completely green. The technology is based on the chemical compound ammonia, some extensive number crunching and one or two engine modifications.

Ghostfishing

Combating marine waste and ghost fishing with new materials

Ghost fishing and plastic waste from the fisheries industry is becoming a major environmental problem. Can we address the issue by using degradable plastics? Scientists at a new research centre are aiming to find the answers and develop the systems we need.

 

Researchers modelling a floating solar farm

Researchers to test a solar farm at sea

The sun shines just as much out at sea as it does on land. There are also no restrictions on area use and seawater even helps to cool the solar panel technology. It’s only a matter of time before the first floating solar energy farms are installed at sea.

A robotic microplankton sniffer dog

The microscopic, free-floating algae called phytoplankton — and the tiny zooplankton that eat them — are notoriously difficult to count. Researchers need to know how a warming climate will affect them both. A new kind of smart, lightweight autonomous underwater vehicle (LAUV) can help.

Fish farms moving onshore

Land-based fish farming offers many benefits to both the fish and the environment. In traditional offshore farms, the fish are vulnerable to sea lice infestation and infectious diseases. Modern land-based aquaculture systems are able to offer local fish products in landlocked countries.

Reveals hungry salmon with sound waves

The feed cost represents about 50 percent of the costs of farming salmon. But how do we know if the salmon is hungry or still full? Researchers have rethought to find answers. The result is less wastage and pollution – and enough food for the salmon.

Meet the aquaculture industry’s new maintenance bot

This ROV can fully operate on its own, and follow along with fish’s behaviour and health with its Argus eyes – all while keeping a safe distance. It even inspects the technical standard of the enclosure while it’s at it. Say hi to Mr. CageReporter.

Successful utilisation of every single gramme of fish

The rest raw materials left after a salmon has been filleted are equivalent to more than 60 percent of its slaughtered weight. It will soon be possible to convert these into a high-quality fish oil, taste-neutral fish proteins, fish gelatin and flame-retardant materials. Ensuring that not a single gramme goes to waste.
