If the Norwegian government rejects the majority opinion of the Gene Technology Committee, it will miss a long overdue opportunity to boost food safety, improve animal welfare and promote more eco-friendly pesticides.
Shooting sound waves through water can remove dissolved gas that results from hydropower production in rivers. This gas can harm fish. Researchers are now ready to test techniques to reduce the risk in real hydropower plants.
Sick and injured farmed salmon are a problem, but researchers have recently developed an implant that uses sensors to gather information about the welfare of individual fish.
Is it only farmed fish that are responsible for spreading salmon lice larvae? Or is it also possible that wild salmon can infect farmed fish? This is what researchers will be trying to find out.
Bacteria-free fish fry put researchers on the track of how they could make fish more disease resistant.
Researchers at NINA, the Norwegian Institute for Nature Research, and NTNU have developed a new method for monitoring salmon lice larvae along the coast. The lice trap is now being tested in the Hardangerfjord.
When salmon ingest parasites, the parasite may not be the only factor that determines the impact on the health of the fish.
Research shows that even fish farmers have doubts as to whether using cleaner fish is an effective delousing method. “Fish farmers tell us that they want a ban on the use of certain species. They’re also very critical of wild-caught cleaner fish being transported,” says researcher Kristine Størkersen. She is one of the scientists who have been helping the Norwegian Food Safety Authority gain an overview of the situation.
The electronic “sensor” fish measures the physical factors that affect farmed fish during delousing. The results may lead to welfare improvements in salmon farm cages.
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.
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.
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.
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.
