Marine fauna colonizing device or artificial reef, has front and rear walls with transversal dimension lesser than longitudinal dimension of lateral walls to reduce resistance of structure, and openings arranged based on their sizes
Marine fauna colonizing device or artificial reef, has front and rear walls with transversal dimension lesser than longitudinal dimension of lateral walls to reduce resistance of structure, and openings arranged based on their sizes
The device or reef (1) has a hollow concrete monoblock structure with parallel lateral walls arranged parallel to tidal stream, and front and rear walls (3, 4) inclined towards an interior of the structure with respect to a base (7) of body of water. The structure has lateral openings (12-15) arranged based on their sizes to allow passage of marine fauna, and inner partitions extended between the lateral walls. The walls (3, 4) have a transversal dimension lesser than longitudinal dimension (y) of the lateral walls to reduce hydrodynamic resistance of the structure against the stream. An independent claim is also included for a marine fauna colonizing installation comprising marine fauna colonizing devices.
