Precision trout: using LCA to optimise Oxygen for better welfare and production
Researchers at Ca’Foscari University have partnered with Troticoltura Leonardi, a family-run rainbow trout farm in northern Italy to implement precision aquaculture, aiming to improve the decision support of farm managers by taking advantage of low-cost sensors, mathematical models of biological processes and data processing methods to optimize the use of oxygen in tanks.
They conducted a Life-Cycle Assessment (LCA) using data collected through precision aquaculture at the trout farm. LCA are environmental assessments of farms, where all resources and impacts for the entire life-cycle of the product are considered. The researchers compared LCAs from before and after the oxygen optimization methods were implemented, and confirmed a reduction in environmental impact with the new system, while providing hints for further improvements.
