Artificial Reefs in the Ligurian Sea (Northwestern Mediterranean): Aims and Results
Abstract:Artificial reefs can play an important part in the restoration of inshore biological resources in the Ligurian Sea in areas where the coastal environment has been affected by three main causes of deterioration: (1) illegal trawling, (2) incorrectly repairing sandy shores with silty materials, and (3) pollution, mainly sewage discharge. The existing artificial reefs and some projects are described. The first artificial reef at Varazze (SV), composed of 1,300 car bodies, did not fulfill fishermen's expectations because of unsuitable substrates, heavy sedimentation and water turbidity. In the Marconi Gulf, wooden barges, dock-gates, concrete blocks and loose stone materials were sunk to produce a final volume of 16,185 m3. The results of official sports fishing competition (using lines) show an increase both in the amount of activity and in quantity of the catches. A recent artificial reef, constructed off Loano with the aim of protecting the Posidonia meadow and replenishing the fishing resources and some similar projects, are also described.
