Selection for adaptation to dietary shifts: towards sustainable breeding of carnivorous fish.
Genetic adaptation to dietary environments is a key process in the evolution of natural populations and is of great interest in animal breeding. In fish farming, the use of fish meal and fish oil has been widely challenged, leading to the rapidly increasing use of plant-based products in feed. Howev...
