Keynote presented on the 29th June 2021 for the HORIZON4AQUACULTURE EVENT WEBINARS. The European Commission in their strategic guidelines for EU aquaculture 2021-2030, aims to achieve eco-intensification, preserve biodiversity, and develop better practices and technologies, Aquaculture is paving the way to be both a more environmentally friendly and more efficient industry. Sharing this goal, the EU H2020 funded projects GAIN, iFishIENCi and IMPAQT launch Horizon4Aquaculture, a three-day online event — 15th, 22nd and 29th June — to work together in 3 key aspects: Policy and Regulation, Circularity, and Precision Aquaculture. Horizon4Aquaculture invites researchers, aquaculture farmers, policymakers, national and pan-national aquaculture development organizations to join the conversation and contribute to the present and future of the sector.

Restorative
Aquaculture
The concept…
Aquaculture operating in
step with natural ecosystem
processes, providing
positive environmental
effects and supporting the
long-term sustainable use of
natural resources.

Precision aquaculture: where?
RAS Wearable
At sea
Real time analysis of
biomarkers using wearable
sensors technology offers
non-invasive data collection.

20. Sensors need to be:
Dr Sara Barrento WHAT IS PRECISION AQUACULTURE? 20
robust
low-cost
capable of underwater and
in-air wireless connectivity
high level of Interoperability
Data Management
Models need to be robust
Security and sovereignty of
data is critical to exploit
technology in an ethical and
commercially sustainable way
Precision aquaculture: moving forward
Avoid YAGI
