Næringsutnyttelse av stor atlantisk laks i kaldtvannsmiljøer

Offentlig prosjektsammendrag

The ongoing climate change has also become for salmon aquaculture operations a burden. The increase in water temperatures seem to influence the robustness of Atl. salmon and its resilience to diseases. Adapted production technologies, developing new vaccine types, implementing improved and new health management programs are already implemented and returning positive effects. Moving production volumes to region with colder water temperatures, (e.g. lower than 6-8 degree Celsius over longer periods in the year), could be an additional measure. Main objective of this study is therefore to investigate whether nutrient requirement calculations need to be adapted when feeding large Atl. salmon at colder water temperatures. A factorial research design, conducted in open net pens at practical conditions was chosen to answer this question.
