| Summary: | Pacific oyster (Crassostrea gigas) aquaculture is one of the largest suppliers of seafood worldwide. For instance, oyster production from British Columbia contributes 60% of the annual shellfish production in Canada. With the expanding industry, there have been growing incidents of mortality events in hatchery production, causing the seed stock shortages limiting sales to nursery growers. Recent studies have attempted to characterize the microbiome (pathobiome) associated with mortality; however, differing effects of harvest sites, tissues, age, and abiotic stresses on the oyster microbiome make it challenging to identify the mortality causes. Thus, there is a need to define the core members of oyster microbiome to serve as a baseline for future hypotheses testing. In the current study, Pacific oysters were obtained from two farm sites differing in location, sampling time, and production stages with the goal of identifying microbial taxa that are consistently found in C. gigas. Bacteria in the genus ... |
