Smarter Fish Farms Aim to Cut Energy Use and Carbon Footprint
Recirculating aquaculture systems (RAS) are gaining traction as a sustainable method for fish farming. These systems significantly reduce water consumption and allow for precise control over fish rearing environments. Furthermore, RAS technology helps lower environmental impacts by filtering and reusing water, minimizing the need for fresh water intake. However, a major drawback of current RAS facilities is their high electricity consumption. This is due to the continuous operation or fixed, often conservative, schedules of essential equipment like pumps, filters, and aerators. These systems require substantial energy to maintain the stable conditions necessary for fish health and growth.
The development of smarter RAS technologies presents an opportunity to address the inherent energy intensity of recirculating aquaculture. By optimizing equipment operation beyond fixed schedules, potentially through AI-driven predictive controls, energy consumption and associated CO₂ emissions could be significantly reduced. This shift could improve the economic viability and environmental credentials of aquaculture, aligning with broader goals for sustainable food production in the coming decade. Future advancements may focus on integrating renewable energy sources and further refining control systems to create truly net-zero impact fish farms.
