This paper uses a vertically integrated salmon farming company as a case study to describe how quantitative genetics and decision support optimisation tools have been used in an aquaculture breeding programme. The complex tasks of maximising genetic progress while managing genetic diversity and avoiding inbreeding are considered at two levels. The first level relates to the management of a nucleus breeding structure for which long term genetic progress and management of genetic diversity are the primary objectives. The second level relates to the tactical selection among available broodstock candidates and their mating to avoid inbreeding. The importance of both effective data management systems and practical implementation of theoretical genetic principles is emphasised.
