Data from: Response of seaward migrating European eel (Anguilla anguilla) to manipulated flow fields
Anthropogenic structures (e.g. weirs and dams) fragment river networks and restrict the movement of migratory fish. Poor understanding of behavioural response to hydrodynamic cues at structures currently limits the development of effective barrier mitigation measures. This study aimed to assess the...

Anthropogenic structures (e.g. weirs and dams) fragment river networks and restrict the movement of migratory fish.
