文摘

Partitions salmon maternal, additive and non-additive genetic effects on growth and survival in aquaculture. Maternal and non-additive effects drove larval size but additive effects predominated at later life stages. Non-additive genetic effects were the most important drivers of survival throughout life. Careful selective crosses can maximize production in aquaculture settings and should be considered more widely.
