New technologies enable scientists to identify the genes that control disease resistance. They also open possibilities for rapid and accurate genetic improvement using this knowledge. But efforts also need to focus on how such technologies can be most effectively implemented considering the biology of the organisms involved and the practical constraints of established aquaculture industries.

New ingredients, old challenges: The impact of heat processing on the protein digestibility and amino acid availability of novel salmon feed ingredients.
Today, only about 15% of global animalprotein
consumption stems from aquatic
raw material (FAO, 2024). With the rising
world population, predicted to reach
between 9.4 and 10.2 billion in 2050
(UN, 2017), a substantial increase in
aquacultural food production is expected
to play a central role in meeting the
future protein demand (FAO, 2024). About
85% of global fish species are already
maximally exploited, and a significant
amount of this protein will come from
farmed aquatic species, like Atlantic
salmon (Albrektsen et al., 2022). -
Vil bidra til tryggere håndtering av settefisk

Stress kan være den manglende koblingen til plutselige massedødshendelser
En ny forskningsartikkel tar for seg hvordan ulike faktorer, spesielt stressindusert CO₂-endring, kan raskt påvirke giftigheten til H₂S, og dermed i ytterste konsekvens kan forårsake plutselig massedød.
