Common Pattern of Gene Expression in Response to Hypoxia or Cadmium in the Gills of the European Glass Eel ( Anguilla anguilla )
European eel (Anguilla anguilla) populations are in decline. Glass eel recruitment has fallen 10-fold since the early 1980s. Estuaries play a fundamental role in the life history of eels because glass eels must pass through them to reach freshwater ecosystems. Unfortunately, because of their geograp...

European eel (Anguilla anguilla) populations are in decline. Glass eel recruitment has fallen 10-fold since the early 1980s.
