Pre-release processes influencing short-term mortality of glass eels in the French eel (Anguilla anguilla, Linnaeus 1758) stocking programme
Abstract The decline in the European eel has led the European Union to require that its Member States establish an Eel Management Plan, which includes a set of measures to help preserve and restore the wild eel populations. Stocking has been conducted in France since 2011 as part of this Management...

For instance, selecting the most suitable release sites to stock or selecting glass eels with good body condition, adjusting the duration of stalling, or limiting the marking should help reduce short-term mortality.
