Researchers from Tallinn University of Technology (TalTech), in collaboration with the Estonian University of Life Sciences, the Norwegian University of Science and Technology, and leading fish farm company SalMar, have introduced a novel robotic solution for the efficient monitoring of fish farms. The study, conducted in partnership with research organization SINTEF, aimed to identify the most effective inspection robots for observing fish in their natural state.
Fish farming, a rapidly growing industry with a global turnover exceeding 3 billion dollars, necessitates advanced technologies to ensure optimal conditions for fish health, feeding, and growth. Professor Maarja Kruusmaa, the Head of TalTech Centre for Biorobotics, emphasized the critical need for technologies capable of reaching every corner of fish farms to observe fish behaviour accurately.
Traditionally, human divers and large underwater robots have been employed to investigate fish behaviour in fish cages. However, these methods have proven to be costly, disruptive, and ineffective in observing fish in their natural state. To address these challenges, the research team conducted experiments to analyse the behaviour of fish in the presence of different inspection robots.
The standout performer in the experiments was the small and slow-moving robot turtle, aptly named U-CAT, developed by TalTech biorobotics researchers. Unlike conventional underwater robots, which tend to startle fish and cause rapid fleeing, U-CAT’s unobtrusive design allows it to approach fish closely without inducing stress. The research provided valuable insights into the development of robots for efficient monitoring of fish farms, including considerations such as robot colour and movement patterns.
Professor Maarja Kruusmaa highlighted the significance of animal-robot interactions, stating that these studies are crucial for inspiring advancements in environmental monitoring and agricultural automation. The successful integration of robotic technology into fish farming operations promises enhanced efficiency and sustainability in the industry, which holds a substantial market share compared to wild fishing on a global scale.
The findings of this collaborative research effort pave the way for innovative solutions in fish farm monitoring, ensuring a harmonious interaction between technology and aquaculture practices.
