Última Evaluation of biomarkers in oyster larvae in natural and polluted conditions ArchiMer Damiens, Gautier; His, Edouard; Gnassia Barelli, Mauricette; Quiniou, Francoise; Romeo, Michèle. Crassostrea gigas D-shaped larvae were subjected to different conditions of temperature and salinity for 24 h and four biomarkers (acetylcholinesterase (AChE) activity, thiobarbituric acid reactive substances (TBARS) levels, glutathione S-transferase (GST) and catalase (CAT) activities) were measured. AChE activity decreased when salinity increased from 25 to 30 and 35 psu at 20 and 25 degreesC. Temperature did not seem to have an influence on AChE activity. TBARS levels increased as a function of salinity when the temperature was maintained at 20 degreesC, whereas at 25 degreesC no effect of salinity could be observed. Variations in GST and CAT activities were not significant with salinity and temperature except that catalase activity was higher at 25...

Larval stages of bivalve molluscs are highly sensitive to pollutants. Oysters from a hatchery from Normandy (English Channel) were induced to spawn, and fertilized eggs were exposed to copper or cadmium for 24 h. Metal accumulation (from 0.125 to 5 mu g Cu L-1 and from 25 to 200 mu g Cd L-1) and MT concentrations were measured in larvae. Compared to controls, larvae accumulated copper and cadmium with an increase in MT concentrations particularly with cadmium (i.e. 130.96 ng Cu (mg protein)(-1) and 12.69 mu g MT (mg protein)(-1) at 1 mu g Cu L-1 versus 23.19 ng Cu (mg protein)(-1) and 8.92 mu g MT (mg protein)(-1) in control larvae; 334.3 ng Cd (mg protein)(-1) and 11.70 mu g MT (mg protein)(-1) at 200 mu g Cd L-1 versus 0.87 ng Cd (mg protein)(-1) and...
