Is proximity to the North Atlantic Drift and the Continental Shelf Current sustaining freshwater European eel populations in western Scotland?
Summary 1. We report on freshwater resident eel numbers in western Scotland based on two time series of data, independent of each other, spanning 28 years and that do not rely upon fisheries information. 2. Data from eel captures on trash screens of a pumping station (1982–2003) on Loch Lomond and e...
