| Summary: | The objective of the WP1 in FutureEUAqua is to assess how the current breeding programmes for salmon, seabass, seabream and rainbow trout can respond to future demands for novel feed compositions, and to make further improvements to disease resistance, climate resilience and animal welfare. For Atlantic salmon (Salmo salar) we estimate the genotype by diet/climate interactions (GxE) in semi-commercial salmon production system and validate best selection methods in salmon breeding programs by comparing traditional BLUP selection with GS/MAS for production and robustness traits. Estimated correlations will be taken as indicators of the magnitude of re-ranking of genotypes across diets/environments. Power calculations are elementary part of the experimental design but unfortunately often de-prioritized, compromising the critical interpretation of the results. A priori power calculations of genetic studies are characterized with multiple uncertainties, such as true relationship structure, number of families and ... |
