Scorff River

The Scorff is a small coastal river in southern Brittany. It originates in the Côtes-d’Armor department, flows through the Morbihan department, and empties into the Atlantic Ocean at the harbour of the town of Lorient.

Its main course, 70 km long, drains a granite and schist catchment area of 480 km². The water, which is slightly acidic, has good quality. Most human activity in the catchment area is agricultural. Most farms produce cattle (more than 50%), followed by poultry (20%), pigs (20%) and crops (filed crops, vegetables, etc.).

The Scorff River and its tributaries create a wide variety of landscapes and habitats conducive to life and remarkable biodiversity. As a result, the Scorff River has a heritage recognised as significant by the European Union (EU) and is included in networks for the conservation of species and their habitats (French natural area of ecological, faunal and floristic interest (ZNIEFF), EU Habitats Directive, EU Natura 2000).

The main species captured are salmon, trout, eel, shad and lamprey. Monitoring activities for migratory fish at the site are the subject of annual reports and stock assessments:

The record rainfall recorded in January did not spare the Scorff watershed from winter flooding. The trapping installations were underwater for several weeks, making all captures impossible. Since the beginning of March, the traps have been active again and ready to welcome the arrival of the first migratory fish, as well as the downstream migration of smolts, which should begin soon.
