The seafood sector is essential for global food security and economic development; however, it encounters substantial challenges, including labor shortages, sustainability issues, and the necessity for enhanced efficiency. Advanced technologies such as robotics, drones, and autonomous systems are increasingly being integrated into multiple stages of the seafood value chain, encompassing harvesting and distribution, to address these challenges. These technologies provide solutions through the enhancement of operational efficiency, improvement of product quality, and promotion of sustainability. This chapter examines the automation of processing and packaging through robotics, the enhancement of aquaculture and fishery monitoring via drones, and the optimization of logistics and environmental management by autonomous systems. The chapter also highlights challenges associated with the adoption of these technologies, such as elevated costs, regulatory concerns, and the necessity for technical expertise. Several real-world use cases are presented to demonstrate the practical application and benefits of each technology. The chapter concludes with recommendations for future research, emphasizing the scalability of these technologies for smaller enterprises, their integration throughout the value chain, and their environmental and social implications. Addressing these areas enables the seafood sector to leverage technology more effectively for a sustainable and efficient future.
