Abstract
Marine protected areas of Sabaudia and Terracina, are established by the Lazio Region, in order to facilitate restocking. They are made using artificial reefs underwater, to counter illegal fishing and Promote the attraction of marine organisms and in particular ensure a particular environment type nursery, sparking a natural food chain capable of supporting juveniles of different species. The underwater barriers have been realized with modular structures certificates type "sea-friendly", according to the UNI EN ISO 14001:2004 for the sector artificial barriers, pre-assembled on the ground by means of bolts of stainless steel marine at low-carbon. The structures were lowered into the sea and geo-referenced, to form a "reef" of "atolls", of about 250,000 a m2 at a bathymetry within 15 and 20 m of depth. The facilities are equipped with holes and space irregulars that reproduce a natural environment and have a pyramidal shape. Those pyramids are easily colonized by fouling and provide shelter and a chance to reproduction for many aquatic organisms, particularly for the fish species of high market value. The objectives of the artificial reefs are: on the one hand encouraging the repopulation of the marine areas concerned and at the same time achieve a optimal high productivity and reduce the fishing effort using the sustainable fishing methods from the environmental point of view, compatible with the system of barriers / atolls of the reef artificial, entrusting the management of a fishery to an cooperative organization type OP (Organization of Production), able to organize and manage a coordinated system of fishing and regulated by specific rules based on monitoring and sampling for the certification the presence and consistence of the biomass, the seasonal of fishing operations, compliance with the quantity of fishing and the selectivity of fishing techniques. The system so designed would allow sustainable production of species of fish of high commercial value and proper management of the marine protected area that will provide new income opportunities for small commercial fishing, as well as ensuring the protection and recovery of the sea vast areas.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
