The Fish Health Report 2023 from the Norwegian Veterinary Institute is now available in English.

According to monthly reports, 37.7 million farmed salmon and 2.4 million rainbow trout (larger than 3 grams) died in land-based hatcheries in 2023. Additionally, 62.8 million salmon and 2.5 million rainbow trout died during the sea phase of production.
