Sea lamprey  (Petromyzon marinus)

Pollution and changes in land use have affected this species (2), and river construction works have prevented migration along many traditionally used rivers (4).

A number of UK sites that support sea lampreys have been designated as candidate Special Areas of Conservation (SACs). Although this will be a good foundation for conserving the species, further action will be required. To this end, a draft Action Plan has been produced to guide future conservation efforts (7). Furthermore the Life in UK Rivers Project is helping to conserve this species (8).
