Gain precise insight into the fish's physiological condition

In a recently published study, we show for the first time that Atlantic salmon can synthesize vitamin D3 endogenously when exposed to sunlight. This surprising finding changes our understanding of vitamin D metabolism in salmon and has important implications for modern aquaculture. First, we discovered that salmon shortly after being released into open-air cages in the sea had significantly higher levels of circulating vitamin D in plasma compared to fish produced in indoor f

I 2023 utviklet vi ved FishLab en ny analytisk metode for kvantifisering av tyroksin (T4) og utvalgte steroidhormoner i fiskeplasma. Metoden er basert på LC-MS/MS (væske-kromatografi koblet til tandem massespektrometri), og gir høy spesifisitet, sensitivitet og analytisk robusthet ved analyse av lave hormonnivåer i komplekse biologiske matrikser.

From the moment the fish is caught until the blood sample is taken, the level of stress hormones in the blood can have risen 1,000 percent. In the feces, however, the level of stress hormones is more stable, which can provide a more reliable and accurate picture of the underlying stress level of the fish. When explaining adverse events in the aquaculture industry, stress is often cited as a triggering or contributing factor. Stress levels are traditionally documented through
