The Return of the Seahorses: A Breath of Life for the Mar Piccolo
by Francesco Cordone
In the tranquil waters of the Mar Piccolo of Taranto, where the blue reflects against a horizon dotted with smokestacks, a slow disappearance had been unfolding for years. The long-snouted seahorses (Hippocampus guttulatus), once abundant inhabitants of these brackish lagoons, saw their population collapse by almost 90% since 2016. Today, however, the sea tells a different story — one of return and hope.
Thanks to a collective effort combining scientific research with a deep love for the sea, the Aquarium of Genoa, CNR-IAS, the University of Bari, and the Municipality of Taranto have achieved what not long ago seemed impossible: returning to the wild young seahorses born and raised in captivity, ready to reclaim their place among the Mediterranean’s underwater meadows.
The “Hotels” That Save Lives
At the heart of the Mar Piccolo Regional Park, three micro-reserves have been established — small zones of total protection where time seems to move more slowly. Here, at depths chosen to meet the needs of 6–7-month-old seahorses, researchers have installed artificial structures affectionately called “seahorse hotels.”
These are not mere shelters: they are temporary homes where young hippocampi can find refuge from predators, feed, and grow strong enough to face life in the open sea.
A Pact Between Sea and Land
Behind this initiative lies a network of people and institutions who chose to work together: researchers, marine biologists, local administrators, and the Italian Coast Guard. This collaboration shows how protecting a symbolic Mediterranean species can become a concrete strategy for safeguarding the health of the entire ecosystem.
Why It Truly Matters
- Active conservation – Not a symbolic gesture, but a concrete action that can be replicated in other parts of the Mediterranean.
- Habitat restoration – The Mar Piccolo was once a natural sanctuary for seahorses, and now it has the chance to become one again.
- Education and awareness – A project that speaks to citizens, fishermen, and travelers, showing that the sea can recover if we give it time and space.
Looking Ahead
The work doesn’t end with the release. Each seahorse is monitored through photo-identification techniques and regular dives, allowing researchers to study their movements and survival rates. The greatest challenge remains fighting illegal fishing and poaching — silent threats that could undermine years of progress. Protecting these micro-reserves means protecting the future of an entire species.
A Message for All of Us
Seahorses are fragile, slow, and extraordinarily ancient creatures. They are living sentinels: if they are thriving, it means the sea is breathing. Their story today is also our story. In Taranto, the return of the seahorses is not only a victory for science but also an invitation to believe that the rebirth of the sea is possible — anywhere.
