The integration of information technology (IT) in fisheries and aquaculture is transforming these industries, addressing the growing global demand for seafood and the need for sustainable practices. The chapter outlines various technological innovations and their applications, such as the Internet of things (IoT), drones, augmented reality, blockchain technology, drones, and robots. These technologies enhance productivity, ensure sustainability, and improve traceability in the seafood supply chain. IoT facilitates real-time monitoring of water conditions and automated feeding, while artificial intelligence (AI) driven predictive analytics aid in fish disease prevention and market trend forecasting. Blockchain ensures transparency from hatchery to consumer, combating illegal fishing practices. Drones and autonomous vehicles streamline surveillance and data collection, and geographic information system (GIS) supports habitat mapping and environmental monitoring. Additionally, advancements in cloud and edge computing, genomics, and biotechnology contribute to more resilient and efficient aquaculture operations. IT is also revolutionizing fisheries education by providing advanced tools and resources that enhance learning and research. The chapter emphasizes the pivotal role of IT in driving a smarter, more sustainable future for fisheries and aquaculture, highlighting the necessity for continued technological adaptation and innovation.
