Charles Høstlund, CEO Norway Royal Salmon
Norway Royal Salmon has announced it is abandoning plans to continue breeding triploid salmon. The news follows a decision by the Ministry of Trade and Industry to order the suspension of future development work on this type of fish until it can be established it is bringing welfare benefits.
The Norwegian Food Safety Authority has decided that no new triploid smolt will be released after the spring of 2022, and that no triploid salmon should be kept at sea past the end of 2023.
Triploid salmon has three sets of chromosomes, unlike ordinary diploid salmon which has two. The extra chromosome, added through hormone treatment, makes the fish sterile, so if they escape and get into rivers they are unable to interbreed with wild fish stocks.

A new virus threatens Norwegian tomatoes
Tomato growers in several countries have in recent years had problems with this new tomato virus, which was first found in Israel in 2014. The virus is called Tomato brown rugose fruit virus (ToBRFV) , says virologist Dag-Ragnar Blystad in NIBIO.
The virus has now spread to both the United States and several European countries. It is very stable and contagious, and once it has entered a tomato garden it is difficult to get rid of. The virus causes damage to the tomato fruits, it can kill entire plants and can consequently cause large loss of income for tomato nurseries.

Per- and polyfluoroalkyl substances (PFAS) in ski wax have been receiving a lot of attention recently, but waxes constitute only a limited part of the problem of the PFAS group of toxicants.
PFAS are a large group of man-made fluorocarbon toxicants, and you are most likely full of them. The toxic substances don t break down and instead accumulate, both in nature and in your body. Due to their extensive use, humans and animals all over the world are continuously exposed to PFAS, says Håkon Austad Langberg, a PhD candidate at the Norwegian University of Science and Technology (NTNU) who has studied several of them in the last few years.
