The sea lamprey (Petromyzon marinus) is a parasitic lamprey native to the Northern Hemisphere. It is sometimes referred to as the "vampire fish". It is sometimes referred to as the "vampire fish". In its original habitats, the sea lamprey coevolved with its hosts, and those hosts evolved a measure of resistance to the sea lampreys.
Conversely, the construction of artificial channels has exposed new habitats for colonisation, notably in North America where sea lampreys have become a significant introduced pest in the Great Lakes. Active control programs to control lampreys are undergoing modifications due to concerns of drinking water quality in some areas.

Sea lampreys devastated the fishing industry of the Great Lakes. Within 20 years of the lamprey entering the Great Lakes, the harvesting of lake trout was reduced by 98%. Control efforts included lampricides, physical barriers, pheromone alarms and baiting, and trapping. The control has been extremely successful in reducing sea lamprey ...
