Salmon lice dominated 2016 fish health challenges in Norway

Updated figures indicate that more salmon die because of changing treatments against salmon lice. Increased resistance against pharmaceuticals lead more and more farmers to choose none pharmaceutical treatments. This is much harder on the fish. It is estimated that 20 percent, or one of every five salmon released into the ocean, is lost. The Norwegian…

Salmon, blue mussel, eider, and eel die from the same vitamin deficiency

Deficiency of vitamin B1 (thiamine) in wildlife is previously known as a problem among certain species within relatively limited geographical areas. Now, researchers at Stockholm University, together with several other research institutions in Europe and North America, show that the thiamine deficiency is far more widespread than previously realized. The results are published today in…

Fishmeal-free Atlantic salmon feed formulation shows promise

Joint research between The Conservation Fund Fresh Water Institute (TCFFI), USDA and EWOS uses new diet for post-smolt to food-size fish. The objective of this project was to evaluate the effects of a fishmeal-free diet on Atlantic salmon post-smolt performance and fillet quality during growout to market-size in a commercial-scale, land-based, closed-containment system using water recirculation technology. The production system…

Eliminating the Need for Antibiotics on the Farm

Consumers are sensitive to the use of antibiotics in the production of food animals, and fear of residues and antibiotic resistant bacteria in their food supply have driven consumers to shun particular products. This happens not just at the producer level, but to entire regions, countries, and species of farmed seafood. Some consumer concerns are…

Health food to reduce sea lice problem

Norway — Currently and for the foreseeable future, sea lice (Lepeophteirus salmonis) is and will be the main challenge for the salmon farming industry. The sea lice live naturally in the ocean. When the number of host fish increases, the amount of lice will also increase. Because the density of salmon in farm cages is…

Vets call EU rules which demand organic fish farms treat illness using homeopathy scientifically illiterate

Veterinarians have criticised EU rules on organic farming that demands that fish are treated with homoeopathic remedies. In line with EU regulations, the first line of treatment for organic fish should be ‘substances from plants, animals or minerals in a homeopathic dilution’, before British and Norwegian vets have called the directives ‘scientifically illiterate’, saying that…

One year later the same behavior was detected in sea trout in Norway. The largest salmon farming nation, Norway, has…
