Community assembly of gut microbiomes in yolk sac fry of Atlantic salmon: host genetics, environmental microbiomes, and ecological processes.

ABSTRACT: In this study, we investigated the influence of host genetics and environmental microbiomes on the early gut microbiome of Atlantic salmon. We aimed at rearing the fish in either r- or K-selected environments, where the r-selected environment would be expected to be dominated by fast-growing opportunistic bacteria and thus represent more detrimental microbial environment than the K-selected water. Eggs from both wild and aquaculture strains of Atlantic salmon were hatched under germ-free conditions. One week after hatching, rearing flasks were inoculated with either r- or K-selected water communities. Three weeks after hatching, no effect of host strain on the gut microbiomes were observed. r-selection was found to take place in the rearing water of all flasks, including in the flasks adde
