Dataset for "What happens beyond the obstacle ? long-term fishway post-passage behaviour of potamodromous fish"

This dataset contains the movement records of tagged fish (barbel Barbus barbus and chub Squalius cephalus) monitored for up to three years after their marking and release. For each individual, the dataset reports its location relative to the release point (defined as 0), with negative values indicating downstream positions and positive values indicating upstream positions. The dataset thus provides a detailed account of longitudinal movements over time for all monitored individuals.
