At GEA, we are aware that designing a fishway (e.g., pool and weir fishways, pre-barrages, etc.) is only the first step in solving the continuity problem in a river, as there is still significant uncertainty regarding their performance. Therefore, their assessment, calibration, and final certification are necessary. In this regard, an important area of work within the group is hydraulic (Valbuena et al., 2020) and biological assessment (using PIT-Tag technology and telemetry) (Bravo-Córdoba et al., 2021), aiming to determine the efficiency and functionality of each passage, as well as advancing knowledge on optimal devices for each case (Bravo-Córdoba et al., 2021; Sanz-Ronda et al., 2019) and target species (Sanz-Ronda et al., 2016). Our main lines of action and research in this topic are:
- Assessment of fishways using PIT-Tag technology
- Hydraulic assessment of fishways
- Study of fish swimming capacity
- Radio tracking of migratory routes using radio-telemetry
- Passability study in hydraulic structures (dams, weirs, gauging stations, etc.)
Accreditations
GEA members hold recognized certificates for animal experimentation for functions A (animal care), B (euthanasia), C (carrying out procedures), and D (designing projects and procedures). Furthermore, members are subject to continuous training to maintain their qualification.
Valid throughout Spain and the European Union.
