Explosive surge in sea lice hits Norwegian salmon farms amid rising water temperatures

Norway's salmon-farming industry is facing a significant challenge with a surge in sea lice populations, described as "explosive" by the Norwegian Institute of Marine Research (IMR). The increase, particularly severe in northern Norway, has been linked to unusually warm water temperatures, which speed up the life cycle of sea lice. Production Area 12 saw a dramatic rise in sea louse larvae, with levels far higher than in previous years. IMR researcher Anne Dagrun Sandvik attributed the surge to temperatures 3C to 4C above normal, allowing lice to mature and reproduce faster, compounding the issue. (Seafood Source)
