Sterlet sturgeon (Acipenser ruthenus) is the smallest species within the sturgeon family. Although some populations are resident, others can migrate for over 300 km — a trait that raises important challenges for farming systems. Despite its use in aquaculture, important aspects of Sterlet sturgeon biology and welfare needs remain poorly understood.
Available evidence suggests that substrate plays an important role in feeding and spawning behaviour, while practices such as artificial reproduction and slaughter still raise major welfare concerns.
In this new post, we explore key aspects of Sterlet sturgeon biology and discuss what they may mean for welfare in aquaculture.

➜FishEthoGroup is a team of motivated professionals focused on improving fish welfare based on their behaviours.
We develop scientific and applied actions to reach our goals by promoting research, helping to disseminate knowledge, giving consultancy, and training about fish welfare.
Want to know more about us? See information below.
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.
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.
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.

If you are interested in scientific and technical expertise applied to welfare in fish farming, please contact us.
We develop custom-made welfare solutions for your initiatives, as consultancy in farms or other facilities, tailored courses, guidance, certification requirements or systems, specific research studies and welfare protocols (see What we do).
