  • EC_Habitats

Marine natural heritage importance

Listed under EC Habitats Directive
National importance Widespread
Habitat Directive feature (Annex 1) Reefs
Large shallow inlets and bays
Estuaries
Lagoons

Biotope importance

The biotope may provide shelter for species, such as fish fry, which migrate into it on occasion. The lumpsucker Cyclopterus lumpus lays its eggs in the biotope.

Exploitation

Kelp species around the world have been exploited over the years as a source of chemicals for industry. Kelp cast up on the shore has long been collected for use as an agricultural fertilizer. More recently Laminaria digitata is commercially harvested in Brittany for alginate production and in Ireland and France for sea-vegetable production (Guiry & Blunden, 1991).
