Monitoring fish health and growth is a critical concern for Zambia’s traditional fish farming industry. This leads to inefficient feeding practices, compromised water quality and reduced farm productivity. TilapAI, a Dutch startup, has developed an innovative AI-powered monitoring system using dual-camera setups and deep learning algorithms. This non-invasive solution continuously monitors fish health and estimates weight in real-time, enabling early disease detection in large fish populations. The system optimises feeding strategies through precise growth data, reducing waste and negative impacts on water quality while improving overall farm efficiency.
