Aquaculture Precision
aquaculture
The farming of
aquatic organisms
Fish
Molluscs
Crustaceans
Aquatic Plants
Amphibians …
The acquisition and
interpretation of data
about the aquatic
environment and farmed
species through sensors
that can provide decision
support for farm
operations.

4. Challenges
Dr Sara Barrento SETTING THE STAGE: WHAT IS PRECISION AQUACULTURE? 4
Harsh environment
Power and connectivity
Large range of spatial scales
Access can be impeded by weather

5. Dr Sara Barrento SETTING THE STAGE: WHAT IS PRECISION AQUACULTURE? 5
Precision Aquaculture
The motivation…
Pressure from consumers
and regulators
Sustainable farming
Better animal welfare
Restorative aquaculture
New real-time sensor
technologies
Farms are getting bigger
and moving offshore

8. Sensors need to be:
Dr Sara Barrento SETTING THE STAGE: WHAT IS PRECISION AQUACULTURE? 8
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
