The effects of 4-nonylphenol (NP) on functional responses of haemocytes from the clam Tapes philippinarum were investigated after 7 d exposure to sublethal NP concentrations (0, 0 + acetone, 0.025, 0.05, 0.1 and 0.2 mg l–1 NP). Haemocytes from both controls and exposed clams were collected, and the effects of NP on uptake of the vital dye Neutral Red (NR), superoxide dismutase (SOD) and lysozym...

The suspension-feeding Manila clam Ruditapes philippinarum is a native species of the western Pacific that is now widely distributed around the globe because of its commercial importance. To determine the adaptive physiological responses to changing thermal and nutritional conditions, clearance, filtration, feces production, ammonium excretion, respiration rates, and scope for growth (SFG) were...

We investigated the response of Manila clam Venerupis philippinarum to possible temperature and salinity changes in a holding facility. First, clams were exposed four temperatures for 15 days. Valve closure survival seawater at 18 °C higher than that those 24 °C. Second, six salinities Survival two fluctuation conditions (24–30 27–24 psu) was lower constant 30 psu conditions. closures low (24 L...

Arcachon Bay, in the southern Bay of Biscay, is first French production area Manila clam (Ruditapes philippinarum) with an annual commercial fisheries around 400 tons recent years. This bivalve mollusc was introduced into bay 1980s for aquaculture purpose and quickly succeeded natural settlement so that its high market value led to progressive establishment a perennial fishery from mid-1990s. L...
