Training AI in the fight against bloodthirsty parasites

Researchers have taken over 120,000 images of salmon lice larvae in seawater and used them to train AI models. The models were much faster and more accurate than experienced biologists at identifying the parasites that feed on the skin and blood of salmonids.

Light environment in fish farms hinders salmon’s sleep rhythms

What happens when you disrupt a fish’s natural rhythm? The use of light in fish farms can stress the fish and prevent them from sleeping or developing properly. New research now makes it possible to measure light from the fish’s point of view. This could greatly improve fish health.

Seafood should not have to fly

A small revolution is happening in the fishing industry. Freshly frozen fish can now be thawed in a new way, and that means you will have access to super-fresh food from the sea – even if you live thousands of miles away.

The superfood that is in ever greater demand

Copepods are the perfect food package for marine fish larvae, such as cod, tuna and halibut. Now research shows that it is possible to drastically increase the production of the fish fry’s superfood.

The Nansen Legacy: Uncovering the secrets of the Barents Sea

Fridtjof Nansen travelled the polar regions as both an explorer and a scientist. Ten research institutions followed in Nansen’s footsteps in a collaborative investigation of the Barents Sea. Their 6-year effort has now been documented in a new book.

Hunting for a new circular feed resource from the sea

Bristle worms and soldier fly larvae can grow on aquaculture sludge and become protein-rich feed for fish and livestock. But toxic substances can infiltrate the loop. Now scientists have learned more about which substances we need to keep an eye on.

Valuable raw materials being discarded at sea

The world needs more of the valuable nutrients found in fish viscera, liver and roe. Yet, much of this raw material is being thrown back into the sea. There are good reasons to stop this wasteful practice.

How scientists will prevent plastic pollution in the ocean

Ropes and fishing gear used in the fisheries and aquaculture industries are a major source of microplastics in the ocean and littering along the coastline. A multidisciplinary international research team has now drawn up a plan that will help to reduce pollution.
