Farming remarks

Thunnus maccoyii
Li1  ❘  Po2  ❘  Ce3

Farming of Thunnus maccoyii started in the 1970s mainly in Australia and Japan as a solution for the observed depletion of stocks and its high market value. This warm-blooded fish is an ocean cruiser, and therefore solutions for farming will be hampered by its need for space. There is already a fair amount of research on this species, but more knowledge is necessary regarding social interactions, stress, malformations and on the development of a humane stunning and slaughter method. Although it is mostly farmed from wild-caught individuals, rearing and housing of spawners should be improved.
