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 کاملVirus-like particles associated with mortalities of the Manila clam Ruditapes philippinarum in England.
Mortalities of the Manila clam Ruditapes philippinarum (Adams & Reeve, 1850) were reported in southern England (Kent and Poole Harbour) during late spring of 2008. In response to these reported mortalities, samples were collected from 5 sites across the south coast of England. Clams were sampled for both histology and electron microscopy. Transmission electron microscopy (TEM) revealed unenvelo...
متن کاملAlterations in hemolymph and extrapallial fluid parameters in the Manila clam, Ruditapes philippinarum, challenged with the pathogen Vibrio tapetis.
In a recent study, we demonstrated the presence of defense factors, competent hemocytes and high enzymatic activities (peptidases, hydrolases, lytic, etc.), in the extrapallial fluid, located between the mantle and the shell, of the Manila clam, Ruditapes philippinarum. In Europe, this species is affected by brown ring disease, an epizootic disease caused by the bacterium Vibrio tapetis. The pr...
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...
متن کاملEcophysiology of Brown Ring Disease in the Manila clam Ruditapes philippinarum, experimental and modelling approaches
Brown Ring Disease (BRD) in the Manila clam, Ruditapes philippinarum, is a disease caused by the bacterium Vibrio tapetis. This pathology was first observed in Northern Brittany (France) in 1987. The pathogenic agent enters in the extrapallial cavity (i.e. the space between mantle and shell), disrupts the normal production of periostracal lamina and causes an anomalous deposition of periostracu...
