Executive summary: Domesticating Atlantic bluefin tuna raises sustainability benefits but also welfare concerns that require more research.
Key points:
Domesticating Atlantic bluefin tuna enables closed-cycle aquaculture, reducing reliance on unsustainable wild catch. However, many larvae still die in hatcheries.
Conditions in captivity like small tanks, noise, and handling may cause stress for these large predator fish. More research on their needs and welfare is required.
Common slaughter methods for small tuna seem inhumane with crowding and spiking. It’s unclear what proportion face this cruel death.
As the industry develops, producers have incentives to ensure good welfare since stress harms meat quality. But welfare is not yet a big priority.
Overall, more research is required on Atlantic bluefin tuna welfare in captivity to guide humane practices as domestication increases.
