Objective OBJECTIVES AND EXPECTED ACHIEVEMENTS 1.1 Background of the eel problemDuring the last two decades a substantial decrease of the European eel (Anguilla anguilla) population was observed in Europe, undoubtedly related with the decline of elver immigration. It is not clear which factor is crucial in the decline of the eel population: fisheries at different life stages of eel, hampering the immigration of glass eel or emigration of silver eel, mortality due to hydro power stations, water quality issues, parasites (e.g. Anguillicola crassus ) or oceanic processes.Impact on the downstream migrating silver eel in inland waters is caused by commercial fisheries and by mortality of eel passing the turbines of hydro power stations. Mortality rates for silver eels range from 13 to 50% at individual hydro power stations. These human activities are widespread in many European rivers and might have detrimental effects on the population level of the European eel.
