Data from: Ocean warming and acidification may challenge the riverward migration of glass eels
The dramatic decline of European eel (Anguilla anguilla) populations over recent decades has attracted considerable attention and concern. Furthermore, little is known concerning the sensitivity of eel's early stages to projected future environmental change. Here we investigated, for the first...

The dramatic decline of European eel (Anguilla anguilla) populations over recent decades has attracted considerable attention and concern.
