Polycyclic aromatic hydrocarbons in clams Ruditapes decussatus (Linnaeus, 1758)
Journal of Environmental Monitoring, 2007The concentration of sixteen individual polycyclic aromatic hydrocarbons (PAHs) was measured in the clam Ruditapes decussatus whole soft tissues from several places of the Ria Formosa lagoon (Portugal). Total PAH (tPAH) concentrations were higher in the summer (August) and winter (January) than in the other months and the distribution pattern of the ...

In situ endocrine disrupting effects of cadmium on the reproduction of Ruditapes decussatus
Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2007The gulf of Gabès is well known for its multiple contaminations which are closely associated with the past and present industrial and anthropogenic activity. In order to evaluate in situ the cadmium bioaccumulation in the clam Ruditapes decussatus sampled in this area, we measured cadmium concentrations in the whole soft tissues and in the digestive ...

Morphological Characterization of the Hemocytes of the Clam,Ruditapes decussatus(Mollusca: Bivalvia)
Journal of Invertebrate Pathology, 1997Hemocytes play an important role in internal defence in molluscs. The morphology of hemolymph cells was studied for the first time in Ruditapes decussatus. Two main types of hemocytes (hyalinocytes and granulocytes) exist in R. decussatus. Three types of granulocytes were identified by light microscopy, in accordance with the presence of basophilic or ...

Abstract Organisms living in coastal ecosystems are frequently subjected to anthropogenic pressures such as metals. Metals, especially those not required for metabolic activity (e.g. mercury, lead and cadmium) can be toxic even at quite low concentrations not only to organisms that accumulate them, but also to their consumers.

TBT effects on the larvae of Ruditapes decussatus
Journal of the Marine Biological Association of the United Kingdom, 2001The effects of sublethal tributyltin (TBT) concentrations on the growth and development of Ruditapesdecussatus larvae were studied. Veliger larvae of R. decussatus were exposed to TBT nominal concentrations of 25, 50, 75 and 100 ng Sn l−1 in the water for a period up to 13 d.

Effects of Temperature Regime on Broodstock Conditioning of Ruditapes decussatus
Journal of Shellfish Research, 2008To optimize the conditioning procedure to obtain better larvae with lower production costs, Ruditapes decussatus broodstock was conditioned at different periods during the year [October (C1), February (C2), and April (C3)] under two different controlled temperature regimes: a constant temperature (CT, 20°C) and a gradual increase in temperature from ...

The presence of Vibrio parahaemolyticus in bivalve mollusc is an important cause of foodborne illnesses, and their levels are influenced by environmental changes, such as temperature and salinity. Clams are common species in estuaries and are used in environmental monitoring programmes. Present study compared the uptake and retention of nonpathogenic V.

Transcriptomic analysis of Ruditapes decussatus oocytes
2012The European clam Ruditapes decussatus is native to the Mediterranean Sea and Atlantic coasts and, while its production is still relatively low in Europe (8 200 tons/year; FAO, 2006), it is a high value seafood product and economically important in many Mediterranean countries (mainly Portugal, Italy and Spain).
