Yield per recruit from stocking two different sizes of eel (Anguilla anguilla) in the brackish Roskilde Fjord
Stocking of young eel is widely practised, as a measure, to meet the management target of the EU eel recovery plan. The target of the recovery plan is to increase the escapement to 40% silver eel biomass, relative to pristine conditions. The scientific information to predict the outcome in silver ee...

Stocking of young eel is widely practised, as a measure, to meet the management target of the EU eel recovery plan.
