Scorff

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

Its main course, 70 km long, drains a granite and schist catchment area of 480 km². The water, which is slightly acidic, is of good quality. Human activity in the catchment area is mainly agricultural. Cattle farming dominates, accounting for over 50% of farms, with poultry farming representing 20%, pig farming 20%, and the remainder comprising farms specialising in crops (arable crops, vegetables, etc.).

The Scorff and its tributaries create a wide variety of landscapes and habitats conducive to life and remarkable biodiversity. As a result, the River Scorff possesses a heritage of recognised European significance and is included in networks for the conservation of species and their habitats (ZNIEFF, ‘Habitats’ Directives, Natura 2000).

The main species caught 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.
