Genetic improvement technologies to support the sustainable growth of UK aquaculture

While the UK is fourth largest aquaculture producer in Europe by volume, it second value with an annual first sale of around £1 billion. Over 90% this from Atlantic salmon farmed Scotland, but other finfish and shellfish species are important to several regions. In review, we describe state art breeding stock supply, how innovation genetics technologies can help achieve Scottish Government’s ambitious target doubling its industry 2030. Particular attention given four most species: salmon, rainbow trout, blue mussel Pacific oyster, contrast highly variable level selective genomics used these sectors. A major factor success farming has been large-scale investment modern programmes, including family selection programmes genomic selection. This proven cost-effective at scale, leading improved production efficiency reduction some infectious diseases. We discuss feasibility applying similar sectors, ensure consistent robust spat supply begin trait Furthermore, species-specific application a global context, future potential genome editing improve commercially desirable traits. Increased adoption will assist industries meet challenges for sustainable expansion, remain competitive market.
