| Summary: | The success of salmon aquaculture is a result of year-round production of consistent size and quality of product to market. This has been achieved through adoption of novel production and husbandry strategies such as Recirculation Aquaculture Systems (RAS) for freshwater smolt production. Differences in water chemistry and microbiota have been reported between RAS and traditional flow-through (FT) systems, nevertheless, the influence of production systems on microbiome-induced changes in gill health is unclear and may explain variable performance seen in farmed stocks. Apart from the rearing system, gill microbial communities can be influenced by life stage, treatment application, disease state and host genetics. This thesis investigated these factors using high-throughput data of gill morphology (histology) and 16S rRNA gene amplicon sequencing data, under commercial and semicommercial conditions in Australia and Ireland. The objective of this thesis was (i) to investigate the relationship between microbial ... |
