Local scale, coastal currents influence recruitment to freshwater populations in the European eel Anguilla anguilla: a case study from the Isle of Man

Abstract

This study examines juvenile Anguilla anguilla (< 30 cm) abundance in five study catchments on the Isle of Man. Preliminary results suggest that juvenile abundance is negatively correlated with increasing coastal current speed at river mouth entry (P < 0·05). These findings indicate that at least under some circumstances, tidally driven coastal currents may influence recruitment to freshwater habitats; therefore, it is presumed that high coastal current speed at the entry to river mouths may reduce the likelihood of freshwater entry.
