Range & Status
A catadromous species found in rivers and on the seashore. Populations of the Common Eel are threatened at present, stocks have declined in recent years, probably due to pollution, over-fishing, habitat degradation, parasitic infection and climate change, all having been forwarded as potential causes of decline. Current information indicates that there has been a major decline in the number of ' glass eels' (unpigmented juveniles, found in estuaries in early spring) during the last two decades throughout Europe, including Britain although Cornish populations seem to be in a good state of health. Listed as critically endangered on the IUCN Red List and also on the UK List of Priority Species (2007).
