Dispersal, recurrence and settlement of Manila clam, Ruditapes philippinarum
The majority of the marine benthos is pelagic in their larval stage. The Manila clam Ruditapes philippinarum, is widely distributed on sandy tidal flats across Japan and a commercially important shellfish. The clam has a planktonic larval stage, which lasts 2 to 3 weeks after hatching. In this stage, the most clam larvae are able to disperse over wide areas with the currents and then settle on ...
متن کاملSediment geochemical controls on CD, CR, and ZN assmilation by the clam Ruditapes philippinarum.
Several important sediment geochemical factors (particle size, contact time, artificial sediment composition, acid volatile sulfide, and pure inorganic particles coated or uncoated with humic acid) were examined for their influences on the assimilation of Cd, Cr, and Zn in the marine clam Ruditapes philippinarum. Metal desorption and phase speciation were concurrently measured for these particl...
متن کاملGenetic differentiation between natural and hatchery populations of Manila clam (Ruditapes philippinarum) based on microsatellite markers.
Manila clam (Ruditapes philippinarum) is one of the major aquaculture species around the world and supports an important segment of the aquaculture industry in China. In this study, we used ten microsatellite markers to detect genetic diversity within six R. philippinarum populations and genetic differentiation between them. A total of 109 alleles were detected across all loci. Compared to wild...
متن کاملVibrio atlanticus sp. nov. and Vibrio artabrorum sp. nov., isolated from the clams Ruditapes philippinarum and Ruditapes decussatus.
Facultatively anaerobic marine bacteria isolated from cultured clams, Ruditapes decussatus and Ruditapes philippinarum, were previously investigated using amplified fragment length polymorphism (AFLP) and 16S rRNA gene sequence analyses. The isolates formed two AFLP clusters and belonged to the genus Vibrio, more precisely to the Splendidus clade. In this study, phylogenetic analyses based on s...
متن کاملHemocytes of the carpet shell clam ( Ruditapes decussatus) and the Manila clam (Ruditapes philippinarum): Current knowledge and future prospects
Hemocytes are the immune effectors in clams, directing cellular but also humoral defences. In the Manila clam (Ruditapes philippinarum) and the carpet shell clam (Ruditapes decussatus), two phenotypically similar venerid species, fishery and aquaculture importance motivated scientific studies to improve knowledge about the participation of hemocytes in immune response. Currently, gaps still per...
