Technical Abstract: Recent advances in aquaculture research include the integration of genomics (study of genes and their functions) into projects pursuing increased aquaculture production efficiency. The genome (genetic material) of every species contains the blueprint that guides its biological processes. Genome research can therefore provide understanding of the mechanisms that drive these processes and provide knowledge to manipulate them for desired outcomes. The primary goal of salmonid genomics as it relates to aquaculture is to identify genes that affect traits associated with aquaculture production and to integrate that information into selective breeding programs aimed at genetic improvement. Desired outcomes include the development of strains which are disease resistant, stress tolerant, fast and efficient growing, and reproductively manageable. To this end, genome tools and technologies must be integrated with other scientific disciplines involved in the characterization of traits such as quantitative genetics, physiology, fish health, and production systems.
