| contents | <p>Ecological studies and restoration efforts in deep-sea environments are a priority for international programs aimed at preserving biodiversity and recovering ocean health. These efforts, however, face technical challenges, particularly in the controlledplacement of megafauna individuals near the seabed. Traditional methods, such as diving with autonomous breathing equipment, are generally impractical for large-scale restoration beyond 50 m depth, while releasing organisms at the sea surfaceleads to high dispersion rates, reducing their chances of reaching the intended location. To address these challenges, we havedeveloped and tested releaser devices equipped with enclosed compartments that mechanically open at a specified distancefrom the seabed, allowing for precise organism release. We designed and deployed various versions of these devices, each suitedfor different field applications, including active restoration actions and ecological studies requiring the safe deployment of indi-viduals near the seabed. Technical descriptions of these devices are provided for replication and further adaptation. Thedevices demonstrated their effectiveness in active restoration efforts, particularly in the mass release of cold-water corals. Addi-tionally, they facilitated ecological studies involving the acoustic tagging of megafauna, allowing for improved monitoring oftheir daily and spatial behavior. The proposed animal release devices offer a practical solution for deep-sea restoration andresearch, ensuring precise organism deployment at designated depths. Their design enhances efficiency in both marine conser-vation and scientific investigations.</p> |
