Around 21 May 2026, partners of the DiadSea project joined the global celebration of World Fish Migration Day (WFMD) through a series of educational and outreach activities across the European Atlantic Area. As a project dedicated to improving the transnational management of diadromous fish at sea, DiadSea was proud to contribute to this international initiative to raise awareness of migratory fish species and the challenges they face throughout their life cycle.

From schools and universities to scientific events and field activities, DiadSea partners engaged diverse audiences to highlight the ecological importance of migratory fish and the need for coordinated conservation efforts.

Raising awareness among future environmental professionals in Galicia

As part of the WFMD celebrations, the Universidade de Santiago de Compostela (USC) organised a field trip along the River Miño and its tributaries, the Deva and the Tea, for around 30 students and teachers training to become environmental officers in Galicia, Spain.

During the excursion, participants gained first-hand insight into the role of river ecosystems in supporting migratory fish species, the pressures affecting these habitats, and the causes behind the decline of many populations. The activity also provided an opportunity to present the DiadSea project and its objectives for improving the transnational management of diadromous fish across the Atlantic Area.

To complement the learning experience, participants played Migr’Ocean, DiadSea’s educational card game designed to raise awareness of the challenges migratory fish encounter during their journeys between freshwater and marine environments.

Educational activities in French primary schools

In France, INRAE visited primary schools in Brittany to introduce more than 100 pupils to the fascinating world of amphihaline migratory fish.

Through interactive workshops, children created fact sheets on different diadromous species and participated in identification activities that helped them recognise these fish and understand the threats they face throughout their life cycle. The sessions combined scientific knowledge with playful learning approaches, encouraging curiosity and environmental awareness among young audiences.

Students also enjoyed playing the DiadSea floor game and card game, which helped reinforce key concepts through collaborative and engaging activities.

To further support awareness-raising efforts, INRAE produced a short video presenting diadromous fish species and their environmental importance in just 30 seconds, making this information accessible to a wider audience.

DiadSea at the I Iberian Congress of the Lima River

In Portugal, the Universidade de Évora participated in the I Iberian Congress of the Lima River, contributing to discussions on river ecosystems and conservation.

The coordinator presented the DiadSea project through a dedicated presentation and an exhibition stand, showcasing the project’s objectives, activities and educational tools. Visitors also had the opportunity to discover DiadSea’s educational games, while learning more about the conservation of diadromous fish and the importance of transnational cooperation for their protection.
