Cornish Red Data (2009)

The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Anguilla anguilla - European Eel

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).
