This English-language conference poster by RAVON calls for ‘Eel Reserves’: areas and migration routes where eels can enter, grow and leave safely without severe pollution, fishing, poaching, pumps or turbines. It outlines the alarming situation in the Netherlands, including glass eel recruitment at around 1% of 1960s–1970s levels, more than 95% of routes being blocked, and substantial mortality and removal. The poster highlights measures such as effective fish passes, fish-friendly pumps and turbines, cleaner habitats, sustainable fisheries and stronger enforcement. It also presents RAVON’s monitoring, research and policy work. The infographic on page 1 contrasts the current situation with a future vision of safe eel reserves. View or download the PDF.
