Abstract

Fish movement plays a crucial role in ecosystem dynamics and has significant implications for the management of species targeted by commercial and recreational fisheries. In this talk, we will present an overview of our research using advanced bio-logging techniques (acoustic telemetry) to study the movement and behaviour of species of commercial and ecological importance in the Balearic Islands. Using high-resolution tracking systems, we have revealed the space use variability and the social structure of an iconic species such as the pearly razorfish (“raor”, Xyrichtys novacula), establishing a fruitful research line on the causes and consequences of fish behaviour. Additionally, through developing a large-scale tracking initiative, the Balearic Tracking Network, we are studying the functioning, effectiveness, and connectivity of the marine protected area network in the region through a multi-species approach. Our findings not only improve our understanding of the drivers of fish behaviour but also provide essential insights for designing effective conservation and management plans in the Balearic Islands.
