IoT-driven smart feeding systems are transforming precision aquaculture by integrating sensors, automation, and AI to deliver optimized feeding strategies. These systems monitor fish behaviour, biomass, and environmental parameters in real time, enabling automated feed adjustments that improve feed conversion ratios, growth rates, and profitability while reducing waste and environmental impact. Technologies such as computer vision, acoustic sensing, and intelligent precision feeding frameworks provide species-specific, adaptive feeding solutions. Integration with farm management systems further enhances operational efficiency and sustainability. Future developments will focus on multimodal data fusion, edge computing, and cost-effective solutions for broader adoption in diverse aquaculture settings.
