A total of 55 juvenile pipefish have been successfully released into the Balearic Sea as part of an ambitious conservation project led by the Palma Aquarium Foundation, marking an important milestone in the protection of one of the Mediterranean’s least-known marine species.
Â
The juvenile broadnosed pipefish (Syngnathus typhle), measuring between 8 and 18 centimetres in length, were released on 24 July in a protected marine area (LIC) in the Bay of Portocolom. All of the fish were born and raised at Palma Aquarium’s marine conservation facilities, where they remained under the care of specialist staff until they were considered large enough to survive in the wild.
Â
Although often overshadowed by their famous cousins, the seahorses, pipefish belong to the same family (Syngnathidae) and play an important role in the health of Mediterranean coastal ecosystems. Their remarkable camouflage allows them to blend almost perfectly into seagrass meadows, making them difficult to spot and one of the least understood groups of fish in the region.
According to the Red Book of Fish of the Balearic Islands, five species of pipefish are found in local waters. However, two are already considered regionally extinct, two are classified as Near Threatened, and one is listed as Vulnerable. Scientists believe habitat degradation and increasing pressures on coastal marine environments are among the main reasons for their decline.
Â
The release forms part of the Pipefish Project (Proyecto Peces Pipa), a conservation initiative developed by the Palma Aquarium Foundation in partnership with Marilles Foundation and supported by TUI Care Foundation. The project aims to improve scientific knowledge of pipefish populations while helping to strengthen their numbers in the wild.
Alongside its breeding programme, the initiative also works with local fishermen to recover pipefish that are accidentally caught, giving researchers valuable opportunities to study the species and support future conservation efforts.
Â
The release operation was made possible with the support of several organisations committed to protecting the Balearic marine environment, including Fundació Joves Navegants, Club Nà utic Portocolom, Cleanwave, the Posidonia Surveillance Service and Club de Buceo 7 Mares.
Â
The successful release of the 55 juvenile pipefish marks the beginning of a new phase for the project. Beyond breeding and releasing fish, the initiative aims to generate valuable scientific data and contribute to the long-term protection of the coastal habitats on which these remarkable species depend.
Â
As conservationists continue working to protect the Mediterranean’s unique biodiversity, projects like this highlight the importance of preserving healthy seagrass meadows and coastal ecosystems—not only for iconic species such as seahorses, but also for their lesser-known relatives that quietly play an essential role beneath the waves.
