Following the collapse of stocks of the European eel (Anguilla anguilla) legislation with the European Community requires member states to improve the escapement of adult silver eels to sea. Measures to improve future eels stocks include the provision of eel screens or behavioural barriers at water offtakes and of elver and eel passes at weirs, sluice gates and other obstructions to upstream river migration.
FGS is able to provide and install a range of technical solutions to enhance upstream eel passage, including bristle passes and moulded plastic substrates. Pumped systems can also be provided for elevated weir crests.
FGS can advise on optimum solutions and positioning of eel passes and provides a full installation and maintenance service.
