Welcome to DiadSea Project
Transnational cooperation to improve the management and conservation of diadromous fish at sea
About the Project
DiadSea project is a transnational cooperation initiative of 9 beneficiary partners and 28 associated partners from 4 European countries (Portugal, France, Spain, and Ireland), led by the University of Évora/MARE, that is aimed at improving the management and conservation of diadromous migratory fish at sea in the Atlantic Area. Diadromous fish live in both fresh and saltwater, which makes it challenging to manage and protect them. They are found in the Atlantic Area, but there aren’t many shared solutions to deal with the problems they face, especially with the added issues of climate change. By protecting these fish and their habitats, DiadSea will not only help the environment but also bring benefits to local communities, both economically and culturally.

Our Work Packages
-
1
Biological data collection
WP1 will focus on collecting biological data during the marine phase of diadromous fish (DF) life cycles to fulfil the lack of knowledge that exists during this phase. Data collected will be used in the development of new tools to predict the effect of climate change on DF marine distributions in terms of habitat suitability and connectivity at a large scale. The WP includes four activities:
-
2
Innovative methods to fill gaps in data-poor species
WP2 will assess novel methodological approaches targeting data-poor diadromous fish to obtain information on the marine life stage of their life cycles. The WP includes five activities:
-
3
Assessment of priority areas for conservation
WP3 will develop new tools to predict the effect of climate change on diadromous fish (DF) marine distributions in terms of habitat suitability and connectivity at a large scale and for all the species targeted by the project. The aim is to identify the suitability of marine habitats and the evolution of this suitability in the context of climate change using several climate change scenarios. The final aim is the identification of priority areas for action to improve the management of these species. Its main output is an improved and updated Interactive Web Atlas.

Transnational management of diadromous fishes
WP4 will develop innovative cooperative solutions to protect biodiversity and the natural resources of diadromous fish(DF) in marine habitat and, subsequently, in freshwater habitat. Its main outputs are: O9 - Implementation of a transnational Observatory; O10 - Policy guidelines for DF management. The WP includes four activities:
-
5
Tools for capacitation and capitalization DF towards sustainability
WP5 aims to deliver sustainable long-term benefits for the management and conservation of diadromous fish (DF) species through a capitalization strategy involving all partners and stakeholders. Its main outputs are: O11 – the creation of an integrated label of origin system; O12 – a card game and comic book around diadromous species. The WP includes three activities:
