New chloride/nitrite ratio 'better for RAS salmon' A study in Norway has recommended that a much higher ratio of chloride to nitrite is necessary to prevent the accumulation of nitrite in plasma and growth losses of Atlantic salmon in recirculating aquaculture systems (RAS).
‘Gentler’ acid proposed as AGD treatment Researchers in Norway and Denmark have concluded that peracetic acid is a more sustainable alternative to hydrogen peroxide to deal with amoebic gill disease (AGD) in salmon.
Study links salmon growth pattern with behaviour characteristics A new study involving the University of Stirling has shed fresh light on the link between the life history of fish and their behaviour.
Sedation of smolts should be used sparingly, say scientists Researchers investigating how sedation of smolts affects the fish have concluded that the practice should be restricted.
Study: Zinc and omega-3 support sea transfer Salmon that had received higher doses of zinc and omega-3 better tolerated the transfer to seawater, according to scientists from Norwegian research institute Nofima.
Feed, clean water and rest are keys to happy lumpfish Good feed and the right environment are key for lice-eating lumpfish to “thrive” at work, research from the Norwegian research institute Nofima shows.
Helping salmon survive the switch to sea More knowledge about barrier functions, including skin, in post-smolt salmon can improve fish health and save the industry millions, according to Norwegian scientists.
Insect meal has ‘high potential’ say researchers after salmon feed trial Norwegian researchers who replaced fishmeal with insect meal in salmon feed found that the salmon grew well, remained healthy and had a good flavour.
Talking our language: welfare indicators handbook now available in English It’s been a long wait, but an English-language version of a successful Norwegian handbook on welfare indicators for farmed Atlantic salmon is now available online.
Vaccine cuts numbers of lice and their eggs in lab tests Laboratory-scale tests by Norwegian and Cuban scientists have shown that a vaccine against lice led to fewer female lice on salmon and at the same time influenced the parasites’ ability to make eggs. The eggs that were made and hatched were further weakened in the second generation.
English version of hit Norwegian fish welfare manual ‘coming soon’ A fish welfare assessment manual that has become a big hit with salmon farmers in Norway will soon be available as a free online document in English, its lead editor has said.
Fish-bone extract leaves salmon in the pink A mineral-rich ingredient that scientists at Norwegian research organisation Nofima have extracted from fish bones has produced unexpected effects.
