Restoration of seagrass habitat and seahorse populations of ria formosa lagoon

SeagHorse

Sobre o projeto

The SeagHorse aimed at the rehabilitation and sustainability of the seagrass habitats and seahorse populations of the Ria Formosa, entailing the following components:

Research: Seasonal monitoring of seahorse population dynamics and of seahorse prey availability in the subtidal habitats of the Ria Formosa: seagrass meadows, unvegetated bottoms and meadows of the invasive green algae, Caulerpa prolifera. Seahorse feeding ecology evaluated using isotopic and gut content analyses, as well as manipulative experiments.
Reconstruction of seahorse habitat (seagrass meadows) planting transplants in the recently created seahorse sanctuary (Edital 15/2020, Capitania do Porto de Faro). Rehabilitation of the seahorse population in the sanctuary using individuals produced in captivity at the Ramalhete fieldstation of CCMAR.
Educational and social activities to expand knowledge about the natural value of seagrasses and seahorses, including teacher training actions and the production of Educational materials.
Transfer of acquired knowledge about the value of seagrasses and seahorses to society and stakeholders of the Ria Formosa.

Seagrass transplants actions between June of 2021 and July of 2022, a total of 8000 plants (4000 of each species, Zostera marina and Cymodocea nodosa) were transplanted to the Sanctuary of Faro.

Reinforcement of natural seahorse populations in two release events of seahorses born and grown in captivity, into the Sanctuary. A total 60 fish were released in November of 2021 and another 200 in May of 2022.

Production of educational material as videos available at the Project website (https://www.seaghorse.pt/recursos.html).

Training actions for teachers of primary and secondary school accredited by the “Conselho Científico de Formação Contínua” (total 25h of training, June and November 2022).

Organization of participative seminars/workshops with stakeholders and authorities of the Ria Formosa, including key decision makers, conservation agents, media, and maritime tourism companies that exploit the image of the seahorse and offer seahorse tours.

Articulation with local schools to disseminate the importance of seagrass and seahorse conservation. Several lectures were held in different schools of the Padre João Coelho Cabanita school group in July of 2022.
