At Munkedal in Västra Götaland, the fisheries association has found many dead salmon in Örekilsälven, all of which have been exposed to fungal attack

It's then that young fishermen can die and that's something we do not discover as easily, "he says.
Predicts reduced stocks
He estimates that the fall measurements will show a significant drop in the density of water courses. The most exposed fishing grounds are those where the water moves and the temperature at the surface and depth is the same.
The effect will probably be as great as we will be further south. According to Håkan Carlstrand, this salmon density will probably be as high in this generation of salmon, in the next four or five years, according to the growth method,
