Inclusion of photoautotrophic cultivated diatom biomass in salmon feed can deter lice.
The aim of this study was to evaluate the potential of diatom (microalgae) biomass as a lice-reducing ingredient in salmon feed.The original hypothesis was based on the fact that polyunsaturated aldehydes (PUAs), e.g.2-trans, 4-trans decadenial (A3) produced by diatoms can function as grazing deterrents and harm copepod development.Salmon lice (Lep
