Article Synopsis
- Microalgae, particularly Chlorella vulgaris, are being studied as health-boosting feed additives in aquaculture, specifically for Atlantic salmon, due to their ability to enhance immune function and manage stress responses.
- In the study, salmon were fed diets with varying levels of C. vulgaris and showed improved feed conversion and protein retention, with notable changes in gut microbial diversity and composition after feeding on higher amounts of the algae.
- Exposure to a stressor (peracetic acid) revealed that fish on higher algae diets exhibited less transcriptional stress response and increased antioxidant protein levels, suggesting that C. vulgaris may help mitigate stress effects in aquatic species.
Smoltification was found to impact both immune and stress responses of farmed Atlantic salmon (), but little is known about how salinity change affects salmon months after completed smoltification. Here, we examined (1) the effect of salinity change from brackish water to seawater on the stress and immune responses in Atlantic salmon and (2) evaluated if functional diets enriched with microalgae can mitigate stress- and immune-related changes. Groups of Atlantic salmon were fed for 8 weeks with different microalgae-enriched diets in brackish water and were then transferred into seawater.

However, relatively little is known about the characteristics that define the adaptive path of microbes to host association. Here we identified microbial traits that mediate adaptation to hosts by experimentally evolving the free-living bacterium Pseudomonas lurida with the nematode Caenorhabditis elegans as its host.
