Combined effects of pollutants and salinity on embryo-larval development of the Pacific oyster, Crassostrea gigas
For several years, low larval recruitment has been observed in Arcachon Bay, in southwest France. Exposure to pollutants could partly account for the reduction of early life stages of the Pacific oyster. This study evaluated the effects of copper and S-metolachlor in combination with salinity on the...

For several years, low larval recruitment has been observed in Arcachon Bay, in southwest France.

Embryos were exposed to concentrations of copper (1, 10 and 50 μg L(-1)) or S-metolachlor (10, 100 and 1000 ng L(-1)) and six salinities (18, 21, 24, 27, 30 and 33 u.s.i).
