Seriola diumerili is a valuable species for aquaculture due to its high commercial value and depleting stocks in the wild. However its welfare in aquaculture is hindered by its spatial needs, since it is a pelagic open water cruiser. In addition, its spawning under farming conditions is majorly induced and invasive, and survival rates of early life stages are very low. Several aspects that are important for farming remain unknown, such as aggression in juveniles and adults, stress, malformation rates and an established humane slaughter protocol. Solving these issues may provide solutions for farming under better welfare conditions.
