Adriatic sturgeon (Acipenser naccarii)
As other sturgeons, Adriatic sturgeon (Acipenser naccarii) is a fish coveted for its caviar, but this one is so endangered due to overfishing that it was probably driven to extinction in the wild. Despite that, this species is still alive thanks to the efforts of regional governments and fish farms that started a reproduction programme in Italy and Spain.
Currently, its farm production is focused on re-population efforts of its natural stocks and caviar production. However, almost no information about this species' biology, natural needs and behaviours is available, making it a significant challenge to assess and improve its welfare state under captive conditions.
Despite that, we already know that it is found in muddy or sandy bottoms and that other sturgeons use substrates like pebbles and stones for hiding and reproduction. Therefore, providing such substrates in captivity can help reach better conditions for this species.

Who we are
Who we are
We are a non-profit association bridging the gaps between science and the stakeholders in the aquaculture sector: producers, certifiers, retailers, NGOs, policy makers and consumers. Our goal is to study and improve the welfare of farmed fishes and other aquatic animals by applying ethological scientific knowledge into best practices in fish farming.

What we stand for
What we stand for
Throughout the years, our team has been involved in many areas of the aquaculture sector, from scientific research to campaigning, from auditing to policy. We use that expertise to promote the welfare of fishes through many initiatives with our partners and collaborators.

What we do
What we do
We develop science-based solutions to assess and improve the welfare of captive and wild-caught fishes. In our approach, we apply a strong background in aquaculture and ethology to address the welfare of fishes. We use state-of-the-art knowledge on the behaviour of a species to understand how its welfare is affected under farming conditions and what we can do to promote it.
