Farming remarks

Huso huso
Li0  ❘  Po1  ❘  Ce0

Huso huso is a long-lived and late maturing species endemic to the Ponto-Caspian Sea region, which includes the Caspian Sea, the Sea of Azov, and the Black Sea. It is also present in the Adriatic Sea, although rare, and is critically endangered due to the construction of hydroelectric dams and the effects of human activities. It spawns in the lower Danube and a few other rivers in Kazakhstan, Azerbaijan, Iran, and Turkey. H. huso is highly valued for its caviar and meat and is intensively farmed. However, there are many knowledge gaps about its natural habitat and behaviour, such as its home range and its social and reproductive behaviour. Currently, the depth and migratory needs of H. huso are not met in farming conditions, the reproduction is highly invasive, and a humane slaughtering method needs to be researched and implemented. Further research in these areas would improve the welfare of the species.
