The RESMED project team installed a fix network with 94 acoustic receivers -or underwater locator beacons- to study the movement of fish in all marine areas of the Mediterranean Sea. There are a total of 25 devices in the marine reserve of Cervera-Banyuls, 28 in the natural park of cap de Creus, 15 in the bay of Roses, and 26 in the natural park of Montgrí, illes medes and Baix Ter. In addition, there are 116 receptors previously installed in the gulf of León by MARBEC Ifremer unit, in Sète (RESMED project collaborator).
In 2024, the project was extended to RESMED+. The objective of RESMED+, as a continuation of RESMED, is to strengthen the MPA network of the area, and to implement conservation actions that cover essential habitats for the species identified in the previous project using acoustic telemetry techniques. In addition, the focus will be expanded to new areas, such as underwater canyons, seagrass beds, estuaries and lagoons, as well as anthropized habitats such as harbors and artificial reefs. The project aims to expand and consolidate the Catalan Tracking Network .
