Stressed fish tend to become unhealthy fish, so it's very important that fish farm operators spot stress as early as possible. A new AI-based system could help them do so, by monitoring the rate at which each fish breathes.

Observing a pen full of salmon at a fish farm will only tell you so much about their well-being. That's why Norwegian scientists have developed an implant that measures and records the vital signs of individual fish, who will serve as "sentinels."

Although salmon farms help take pressure off wild stocks, the penned fish do produce a lot of waste which is concentrated at one location. A new farm is exploring a solution to that problem, by raising salmon and kelp in adjacent 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.

​Sea 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.

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.

Depending 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.

​Many seafood connoisseurs will tell you that fresh fish is without a doubt the best kind to use, with frozen coming in a distant second. According to a new study, however, frozen fish can be just as good as fresh, if not better – as long as the correct steps are followed.

​When fish are processed in trawlers at sea, the animals' heads, guts and skeletons all just go overboard. It's a lot of waste, so Norway's SINTEF research group has developed a system that puts everything but the bones to use.

When people have nerve problems such as those caused by spinal injuries, they can lose the ability to feel when their bladder is full. A tiny new sensor may offer an improved method of assessing their condition, to see if surgery is required or if medication will suffice.

Norwegian researchers have filed a patent to store potential energy at the bottom of the sea.

The robotic CORBYS platform incorporates an exoskeleton that trains stroke victims to walk normally again.
