Petromyzon marinus sea lamprey spawning grounds are located within the framework of the Sélune Observatory. As this species is migratory, its colonisation of the Selune and tributaries will probably be influenced by the removal of the Sélune dams.
Spawning grounds are characterised by a depression accompanied by a sedimentary ejection dome immediately downstream. The stones returned to the dome are clearer, making nests easily visible and identifiable up to several weeks after spawning.
