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

- Statement
-
Spawning grounds are located in the field by two operators, either by kayak (from upstream to downstream) for the Sélune, or on foot (from downstream to upstream) for the two tributaries: Le Beauvron and l'Oir. Each operator followed one half of the bed (right or left). Only clearly marked spawning grounds were geolocated using GPS (theoretical accuracy in XY: 20m).
The list of fields presented in this dataset is specified in the associated catalog.
