Swedish scientists have noted a significant decline in the population of wild salmon in the Baltic Sea, with the numbers being a fifth of what was observed several years ago.

Norway's salmon products, which dominate Swedish stores, are a major contributor to this issue. Climate change and the rearing of salmon in sea farms are the primary threats to wild salmon, according to scientists.

This year the situation is about the same." A similar situation ...
