The Spanish tuna fleet, known for its advanced technology, has initiated the 'SelecTuna' project in collaboration with Satlink, aiming to use over 1,500 smart buoys in the Atlantic, Pacific, and Indian Oceans. This project is designed to enhance fishing selectivity, focusing on sustainable species and avoiding vulnerable ones. The smart buoys, equipped with advanced acoustic technology, can differentiate between various tropical tuna species, enabling the Spanish fleet to target its preferred species more effectively. The data collected will also be used for scientific research on tropical tuna populations, aiding in the preparation of abundance indices and informed decision-making. This initiative underscores the fleet's commitment to sustainable and responsible fishing practices.
