Lampetra fluviatilis

Range & Status

An indigenous species, found in estuaries, rivers, streams and lakes with easy access from the sea. In Cornwall, this species appears to prefer streams with sandy or stony beds as spawning sites. The larvae live buried in mud for 5-6 years prior to migrating to the sea. An apparently rare species, only recorded in east Cornwall (e.g. River Camel and River Tamar) where it can be relatively common in the spring. Listed in EC Habitats Directive in Annex IIa and Va, and in Appendix III of the Bern Convention. The River Lamprey is on the List of UK Priority Species.
