It is a very small charming fishermen village located in the southern homonymous lagoon in the furthest South of Oristano Gulf, outlined by Torre Vecchia and Torre Nova, two Old Spanish Towers built in the 1600s.
The village is on a huge lagoon viewing Capo Frasca and Torre Vecchia promontory. Here there is a narrow sea strip with a tiny sandy beach where the characteristic flat bottom lagoon boats are moored.
Marceddì lagoon is characterized by salty ponds. In the North there is Corru s'ittiri pond, while in the South, in a huge and deep creek, there are St. Giovanni pond, with its fresh water for Rio Mannu and Rio Mogoro inflow, and Manceddì pond which is further with its salty water.
Although Marceddì village is not in the Costa Verde's borders, it should be taken under consideration as it is well known for its high quality and fresh fishing products. This products range from delicious shellfish, clams and black clams and for its huge variety of fish as mullets, marmora, sea basses, giltheads, plain surmulets and murexes.
Thanks to the ponds, fresh and salty water, muddy shores and food abundance, a huge variety of birds nest in this area. Among them there are: the red heron, the purple gallinule, the diving duck, the pond osprey, the mallard, and the small and big svasso. This area is under the preservation of nature of the Ramsar convention on the humid areas.
The arsella (clams) fishing
Marceddì pond is an area where a particular kind of clam is reared. This clam, called arsella, is very appreciated by many gourmets.
It differentiates from the other clams due to its extending valves shape, its siphon urging out from its particular lined shells. Their colours can range from black and white (cocciue pintade) to black (cocciue niedde) which are the most requested, or those white ones with their round and lined shells. These clams are less requested.
The arsella fishing occurs between May and August, they can be found 10/15 cm under the sand. They are carefully drawn respecting the environment. Fishermen use a bottom glass box called mirror. They observe the bottom of the sea searching for two little holes formed by the arselle siphons, they dig into the sand with a special device to extract the molluscs.
