The COFIB marine fauna department was created in 2019 to deal with the new nesting events of sea turtles (Caretta caretta) that took place that same year in the Balearic Islands.
It develops and coordinates the ‘Head Starting’ programme for sea turtles (Caretta caretta) that are born on the Balearic Islands. The main objective of the project is the controlled rearing of hatchlings over 12 months before reintroducing them to the marine environment. By increasing their size and weight considerably, the individuals that are reintroduced to the wild are better prepared for survival, facilitating their development to adulthood and reproduction in their natural environment.
In addition to the development and coordination of this programme in the Balearics, the department is responsible for the coordination and management of all sea turtle nesting events that take place in our islands.
NESTING OF SEA TURTLES IN THE BALEARIC ISLANDS
Since then, the department has been responsible for coordinating and managing all nesting events that occur in the archipelago, protecting and monitoring the nests, relocating them if necessary, taking some of the eggs to an artificial incubator and coordinating awareness-raising and volunteering activities around these events.
En la gestión de estos sucesos se cuenta con la colaboración de los Agentes de Medio Ambiente, las administraciones locales implicadas, personas voluntarias y, en ocasiones, entidades ambientales de la zona en cuestión.
In the Balearic Islands, to date, the following nesting events have been detected:

HEAD STARTING SEA TURTLES PROGRAM
This team is also responsible for coordinating and developing the Head Starting programme for turtles born from nests found in the Balearic Islands, as well as in other autonomous communities in Spain. The main objective of this project is to raise the hatchlings in a controlled manner and, approximately 11 months later, release them into the marine environment. In this way, by entering the sea at a considerably larger size and weight, their conditions are more favourable, increasing their probability of survival and facilitating their development towards adulthood and reproduction.
The Head Starting programme is carried out in close collaboration with other centres, both in the Balearic Islands and on the peninsula, sharing the methodology, coordinating actions and even exchanging specimens born in different autonomous communities. In this way, the chances of success of the programme are maximised for all participating centres and more solid scientific results are achieved, which contribute to the useful information available for the conservation of the species.
The collaborating centres for the Head Starting Programme to date have been the Palma Aquarium Foundation (Balearic Islands), the Cabrera National Park Visitor Centre (Balearic Islands), the CRAM (Catalonia), the Oceanogràfic (Valencia) and the Seville Aquarium (Seville).
AWARENESS CAMPAIGN FOR THE DETECTION OF SEA TURTLE NESTS
In 2022, the Marine Fauna Department launched an environmental education campaign in connection with nesting events, which has been continued in subsequent summers. The campaign consists of informing citizens of the possibility of encountering sea turtles nesting on our coasts and explaining how to act appropriately, whether they encounter a turtle making a nest, a turtle track or hatchlings emerging from the sand. The main message is to convey to the population the importance of immediately calling 112 and not disturbing the animal or interfering with its activity, remembering that it is a protected species and very valuable to marine ecosystems.
For this purpose, a video was edited, in five different languages, which provides this information in a visual, short and understandable way. With the collaboration of local administrations, stickers with a QR code leading to the video have been distributed, so that they can be displayed on beaches, in tourist establishments and at points of interest, getting the message across to both local and visiting populations.
The Head Starting programme is carried out in close collaboration with other centres, both in the Balearic Islands and on the mainland, sharing the methodology, coordinating actions and even exchanging specimens born in different autonomous communities. In this way, the chances of success of the programme are maximised for all participating centres and more solid scientific results are achieved, which contribute to the useful information available for the conservation of the species.
The collaborating centres for the Head Starting Programme to date have been the Palma Aquarium Foundation (Balearic Islands), the Cabrera National Park Visitor Centre (Balearic Islands), the CRAM (Catalonia), the Oceanogràfic (Valencia) and the Seville Aquarium (Seville).
PROYECT RAJIBAL
Since its creation, the COFIB Marine Fauna Department has been growing in staff and resources to develop different conservation and research projects with endangered marine fauna, and in 2021 it started a project to monitor elasmobranch populations in the Balearic Islands.
The project, called RAJIBAL, consists of studying some species of threatened sharks and rays, which are present in our waters and for which there is not much information available. At the moment, the target species are the manta ray (Gymnura altavela) and the white ray (Rostroraja alba). Through transects with diving and snorkeling equipment, the use of visual tags and acoustic telemetry, seabed surveying with an ROV, collaboration with diving centers and work with the fishing sector, valuable information is being collected on their populations and their distribution areas, which can be very useful for the conservation of these and other species.
The Marine Fauna Department carries out a large part of its activity at the facilities of IRFAP-LIMIA, the Marine Research and Aquaculture Laboratory belonging to the Regional Ministry of Agriculture, Fisheries and the Natural Environment. The collaboration with this centre, located in Port d’Andratx, allows COFIB to have the facilities and resources necessary for the development of its actions related to the marine environment.
The Ministry of Ecological Transition and Demographic Challenge MITECO is responsible for the recovery and management of marine wildlife,
The actions are coordinated with the Balearic Government and COFIB.
