Delineation of Pb contamination pathways in two Pectinidae: the variegated scallop Chlamys varia and the king scallop Pecten maximus.
Bioaccumulation of Pb was determined in Chlamys varia and Pecten maximus exposed to (210)Pb via seawater, food and sediment. Both scallops readily concentrated dissolved Pb with whole-body 7-d concentration factors of 250+/-40 and 170+/-70, respectively. In both species, more than 70% of Pb taken up from seawater was strongly retained within tissues (biological half-life>1.5 month) whereas Pb i...
متن کاملInterspecific and geographical variations of trace element concentrations in Pectinidae from European waters.
Cd, Cu and Zn were analysed in the organs and tissues of the three scallop species from the Bay of Biscay, the variegated Chlamys varia L., the queen scallop Aequipecten opercularis L. and the common scallop Pecten maximus L. for interspecific comparisons. In P. maximus the greatest concentrations of Cd and Cu were found in the digestive gland, whereas the two other species showed similar level...
متن کاملAntioxidant response of the variegated scallop (Chlamys varia) under anthropogenic impact
The variegated scallop (Chlamys varia L.) is an important economic resource in the aquaculture sector in Spain. The aim of the present study was to determine the oxidative status of C. varia, exposed to anthropogenic activities in waters of the Mallorca Island (Western Mediterranean). Specimens were collected from two locations attending to a different degree of human impact. The first station ...
متن کاملEvaluating the Potential of Bivalve Scallop (Bivalvia: Pectinidae: Scallop) in Biofiltration of Wastewater in Shrimp Farms from Guowater Bay, Chabahar
In this study, the Scallop bivalves were used for biofiltration of wastewater in shrimp farms during spring 2018 from Guowater Bay. Sedimentation, biological and aeration ponds were prepared for biofiltration around the main pool, then, oyster bivalves were collected from natural environment (sea) and were placed in these pools. Concentration of quality parameters were investigated in four samp...
متن کاملDe Novo Assembly and Characterization of Two Transcriptomes Reveal Multiple Light-Mediated Functions in the Scallop Eye (Bivalvia: Pectinidae)
BACKGROUND The eye has evolved across 13 separate lineages of molluscs. Yet, there have been very few studies examining the molecular machinary underlying eye function of this group, which is due, in part, to a lack of genomic resources. The scallop (Bivalvia: Pectinidae) represents a compeling molluscan model to study photoreception due to its morphologically novel and separately evolved mirro...
