Longitudinal Analysis of the Gill microbiomes of Atlantic Salmon from four Scottish farms reveals dynamics in bacterial richness and seasonal trends in diversity.
Atlantic Salmon aquaculture in Scotland is a major industry being both Scotland, and the UK’s largest food export. Gill disease, in particular Complex Gill Disease, is a significant challenge of salmon production. It is increasingly understood that the microbiome can influence host health and immuni...

Atlantic Salmon aquaculture in Scotland is a major industry being both Scotland, and the UK’s largest food export. Gill disease, in particular Complex Gill Disease, is a significant challenge of salmon production. It is increasingly understood that the microbiome can influence host health and immunity. Therefore, the objective of the study is to identify and characterise the gill microbiome from stocking to harvest from four sites in Scotland 2018-2020. At each site, mucosal gill swabs were collected fortnightly (sites A & C) or monthly (sites B & G) from eight fish in two pens (n=623 fish).
