It's important for fish farmers to keep track of the number of fish in their pens, but doing so involves going in and actually netting out some of the fish. According to new research, echo-sounding tech could soon serve as an easier alternative.

How hungry are your salmon? It's an important question in aquaculture, and by using a combination of audio sensors and artificial intelligence, the Smart System for Feeding Control (SICA) offers a new way to answer it.

While ocean-based fish farms do help take pressure off of wild stocks, they have eco-unfriendly drawbacks of their own. A new underwater robot is being designed to address that situation, by autonomously inspecting the fish and their pens.

Scientists at Norway's SINTEF have developed a way to turn as much of a salmon as possible into useful products, including food supplements and fire retardants. By using new low-temperature processes, the goal is to use every last gram of the fish.

If you're in a road tunnel that suddenly gets filled with smoke due to a vehicle fire, it can be very difficult knowing which way to head. That's where EvacSound comes in, as it uses audio beacons to guide people to safety.

In the face of climate change, reindeer are resorting to eating kelp seaweed, according to new research. The creatures in question are Svalbard reindeer, a sub-species of wild reindeer.

It was a couple of years ago that we first heard about the Eelume, an eel-like robot designed to perform underwater maintenance and inspections. Well, the latest version of the device, known as the EELY500, is about to begin sea trials in Norway.

ScienceSea lice infestations are a common problem in salmon farms, and while there are chemical-free ways of getting the parasites off the fish, they're kind of rough. A new device is being put through one such delousing process, in order to measure just how hard it is on the salmon.

Although many people like the fact that electric cars don't produce engine noise, this means that blind pedestrians can't hear them coming. Having the cars emit a warning sound is one solution, and a new system could help keep that sound from being any louder than necessary.

So-called "ghost" fishing nets are awful things. Lost or forgotten during commercial fishing operations, they can drift in the ocean for years, indiscriminately catching marine life as they do. A newly-invented tag, however, may help keep that from happening.

When someone has a head injury, it's vitally important to know if they're experiencing elevated intracranial pressure – it can cause damage to the brain and spinal cord if left unchecked. A newly-developed device could make the diagnosis process faster and easier than ever before.

ScienceDepending on where they occur, tropical cyclones are also known as hurricanes or typhoons. No matter what you call them, though, they're caused by the evaporation of warm ocean surface water. Norwegian scientists are now looking at stopping them, by using bubbles to cool that water down.
