It is well known that gut bacteria can play key roles in host health and changes in microbiome diversity and compositions have been associated with diet, disease development and the environment the host encounters. The gastrointestinal microbiota of mammals has been studied extensively and significant progress has been made in the same area for aquacultured finfish. However, there are still gaps in knowledge around how the finfish microbiome is associated with health and productivity, particularly in a commercial aquaculture setting. The aims of this Thesis were to characterise the bacterial constituents of Tasmanian Atlantic salmon (Salmo salar) microbiomes to 1) assess the impact of time from feeding on measurement and quantification of gut microbiota composition and determine the effectiveness of the faecal scoring method as a rapid way to assess digestive status; 2) examine the effect of the early life production cycle and rearing environment on the composition of host-associated microbiomes; and 3) ...
