United KingdomA study published in Movement Ecology analyzed the migration patterns of Atlantic salmon, sea trout, and sea lamprey through the Haringvliet Sluices using data from 1,751 tagged fish collected between 1996 and 2018. The research revealed that less than one-third of migratory fish successfully entered the Rhine-Meuse delta, with most passing through the sluices during specific time windows, particularly toward the end of discharge periods when water levels and flow velocities were more favorable. The study also noted differences in passage behavior among species, with Atlantic salmon showing high selectivity for specific conditions and timing, while sea trout exhibited greater variability. Some fish bypassed the Haringvliet Sluices entirely by using the Port of Rotterdam as an alternative route.
