The paper shows that the saccus vasculosus transcriptome response to seawater exposure in Atlantic salmon depends on photoperiodic history and identifies ependymin as a major secretory output.

The paper identifies a major locus on chromosome 14 associated with gill gene expression and somatic growth in Atlantic salmon during smoltification.

This study examines the impact of different light regimes on growth, survival, and genetic parameters of Atlantic salmon, finding no significant long-term effect on size but increased mortality under continuous light.

The paper develops gene expression-based predictive models for survival and growth in seawater using gill transcriptomes of Atlantic salmon, finding photoperiod-sensitive genes are more important than previously thought sodium pump genes.

This study uses single-nuclei RNAseq to analyze Atlantic salmon gill during smoltification, identifying 20 cell clusters and showing immune reprogramming associated with seawater transfer.
