Synonyms[1]

The grooved carpet shell, or Palourde clam,[2] Ruditapes decussatus, or Venerupis decussatus, is a clam (bivalve mollusc) in the family Veneridae. It is distributed worldwide and due to its ecological and economic interest has been proposed as a bioindicator.

This species is one of the most popular and profitable mollusc of lagoonal and coastal sites in the Mediterranean, where it was collected for a long time as food. It is consumed fresh and canned.

Clam

Clam

Clam is a common name for several kinds of bivalve molluscs. The word is often applied only to those that are edible and live as infauna, spending most of their lives halfway buried in the sand of the seafloor or riverbeds. Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. They live in both freshwater and marine environments; in salt water they prefer to burrow down into the mud and the turbidity of the water required varies with species and location; the greatest diversity of these is in North America.

Family (biology)

Family (biology)

Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family".

Veneridae

Veneridae

The Veneridae or venerids, common name: Venus clams, are a very large family of minute to large, saltwater clams, marine bivalve molluscs. Over 500 living species of venerid bivalves are known, most of which are edible, and many of which are exploited as food sources.

Bioindicator

Bioindicator

A bioindicator is any species or group of species whose function, population, or status can reveal the qualitative status of the environment. The most common indicator species are animals. For example, copepods and other small water crustaceans that are present in many water bodies can be monitored for changes that may indicate a problem within their ecosystem. Bioindicators can tell us about the cumulative effects of different pollutants in the ecosystem and about how long a problem may have been present, which physical and chemical testing cannot.

Description

The shell is broadly oval to quadrate with the umbones distinctly anterior. The posterior hinge line is straight, the posterior margin truncate, and the anterior hinge line grades into the down-sloping anterior margin. It is prominent posteriorly, where the shell is conspicuously decussate. The surface has a sculpture of fine concentric striae and bolder radiating lines. Growth stages are clear. The lunule and escutcheon are poorly defined. Each valve has three cardinal teeth: the centre one in the left valve, and centre and posterior in right are bifid. The pallial line and adductor scars are distinct. The pallial sinus is U-shaped, not extending beyond the midline of the shell, but reaching a point below the posterior part of the ligament. The lower limb of the sinus is distinct from the pallial line for the whole of its length. The inner surfaces of the shell are glossy white, often with yellow or orange tints, and with a bluish tinge along the dorsal edge. The overall color is cream, yellowish, or light brown, often with darker markings.[3]

Location

Despite improper management in the past, some regions in the Atlantic coast of the Iberian Peninsula, including Portugal's Algarve, Spain's Galicia and of the Mediterranean basin, as well as Ireland, currently have solid populations of Ruditapes decussatus.[3][4][5]

Iberian Peninsula

Iberian Peninsula

The Iberian Peninsula, also known as Iberia, is a peninsula in south-western Europe, defining the westernmost edge of Eurasia. It is divided between Peninsular Spain and Continental Portugal, comprising most of the region, as well as Andorra, Gibraltar, and a small part of Southern France. With an area of approximately 583,254 square kilometres (225,196 sq mi), and a population of roughly 53 million, it is the second-largest European peninsula by area, after the Scandinavian Peninsula.

Algarve

Algarve

The Algarve is the southernmost NUTS II region of continental Portugal. It has an area of 4,997 km2 (1,929 sq mi) with 467,495 permanent inhabitants and incorporates 16 municipalities.

Spain

Spain

Spain, or the Kingdom of Spain, is a country primarily located in southwestern Europe with parts of territory in the Atlantic Ocean and across the Mediterranean Sea. The largest part of Spain is situated on the Iberian Peninsula; its territory also includes the Canary Islands in the Atlantic Ocean, the Balearic Islands in the Mediterranean Sea, and the autonomous cities of Ceuta and Melilla in Africa. The country's mainland is bordered to the south by Gibraltar; to the south and east by the Mediterranean Sea; to the north by France, Andorra and the Bay of Biscay; and to the west by Portugal and the Atlantic Ocean. With an area of 505,990 km2 (195,360 sq mi), Spain is the second-largest country in the European Union (EU) and, with a population exceeding 47.4 million, the fourth-most populous EU member state. Spain's capital and largest city is Madrid; other major urban areas include Barcelona, Valencia, Seville, Zaragoza, Málaga, Murcia, Palma de Mallorca, Las Palmas de Gran Canaria, and Bilbao.

Galicia (Spain)

Galicia (Spain)

Galicia is an autonomous community of Spain and historic nationality under Spanish law. Located in the northwest Iberian Peninsula, it includes the provinces of A Coruña, Lugo, Ourense, and Pontevedra.

Ireland

Ireland

Ireland is an island in the North Atlantic Ocean, in north-western Europe. It is separated from Great Britain to its east by the North Channel, the Irish Sea, and St George's Channel. Ireland is the second-largest island of the British Isles, the third-largest in Europe, and the twentieth-largest in the world.

Uses

Ruditapes decussatus is cultured from the Atlantic coast of France, Spain, Portugal and in the Mediterranean basin. It is often grown with other bivalves (Venerupis pullastra, Venerupis rhomboides, Venerupis aurea, Dosinia exoleta and Tellina incarnata). Their main predators are shore crabs (Carcinus maenas); starfish (Asterias rubens and Marthasterias glacialis); gastropods (Natica sp.); and birds (Larus sp). An individual Carcinus maenas (6.5 cm width) can consume 5 or 6 clams per day. Marine aquaculture production of grooved carpet shell in 2003 was 3,007 t in Portugal, which excludes non-aquaculture harvesting of the species.

Between 1997 and 2001 total aquaculture production varied between 3,700 and 4,900 tonnes, from five countries. Most was produced by Portugal but France and Spain have also been significant producers; however, the contribution from France is now much lower than before; in 1995 it was by far the leading producer with nearly 5,200 tonnes but in 2004 it produced only 475 tonnes. Global production seems to be declining; in 2004 it was only 2,700 tonnes but the United Kingdom had appeared as a minor producer.

It is consumed fresh and canned.[3]

Dosinia exoleta, common name the rayed artemis, is a saltwater clam, a marine bivalve mollusc in the family Veneridae, the venus clams.

Carcinus maenas

Carcinus maenas

Carcinus maenas is a common littoral crab. It is known by different names around the world. In the British Isles, it is generally referred to as the shore crab, or green shore crab. In North America and South Africa, it bears the name european green crab.

Common starfish

Common starfish

The common starfish, common sea star or sugar starfish is the most common and familiar starfish in the north-east Atlantic. Belonging to the family Asteriidae, it has five arms and usually grows to between 10–30 cm across, although larger specimens are known. The common starfish is usually orange or brownish in color, and sometimes violet; specimens found in deeper waters are pale. The common starfish is found on rocky and gravelly substrates where it feeds on mollusks and other benthic invertebrates.

Aquaculture

Aquaculture

Aquaculture, also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants. Aquaculture involves cultivating freshwater, brackish water and saltwater populations under controlled or semi-natural conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Mariculture, commonly known as marine farming, refers specifically to aquaculture practiced in seawater habitats and lagoons, as opposed to freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain fish products as food.
