Task groups

All about our task groups

SUDOANG is structured around 8 Task Groups (TGs), each Task Group led by a partner, with the contribution of the other partners. To achieve their objectives, the TGs are organized around several Activities, whose main result is a Product. As the project progresses, these products will be available by clicking on the links below.

In the TG Data Collection, all data on the eel and its habitat will be compiled in a database, which will be displayed in a user-friendly and attractive way, in the format of an eel atlas. Such data will be standardised by the TG Eel Monitoring Transnational Network, which will produce common protocols and templates and organise training seminars for those responsible for field and laboratory work. In the TG Estimation of Mortality caused by barriers, the task group will prepare an interactive map with the barriers that most impact the eel stock, in order to establish priorities in actions to improve river continuity. The Recruitment TG will use and adapt the GEREM model to estimate the entry of glass eels into river basins. By comparing these values with the escapement estimates, it will be possible to establish input/output balances during the eel continental phase. The Escapement TG will estimate the biomass of silver eels leaving the river basins to breed. The interactive web application will bring together the maps and tools developed by other TGs of the project. The TG Intersectoral and Intergovernmental Dialogue will explore new management approaches to address the administrative complexity of managing the species, with the focus on jointly building the eel governance platform.
