Última Approche de l'état physiologique de l'huître creuse Crassostrea gigas au cours d'un cycle saisonnier à Marennes-Oléron ArchiMer Moal, Jeanne; Samain, Jean-francois; Bodoy, Alain; Le Coz, Jean-rene. The energy charge was measured for two Crassostrea gigas populations, during an annual survey at Marennes Oleron, to appreciate the condition of health of these oysters. It is assumed that the actual decrease in production of this area is related to a biomass overload which affects the oysters by lowering their scope for growth. Energy charge, an index developped by ATKINSON (1968), defines the energy equilibrium of organisms. It is the adenylic nucleotide ratio: E.C = (ATP + 1/2ADP)/ATP + ADP + AMP). We have measured this parameter to determine the state of health of these oysters. A methodological study has been conducted previously to define the conditions of sampling, conservation and extraction for a HPLC assay. The HPLC method (high performance...

Adenylatc Encrgy Charge (AEC) values of Crassostrea gigas (9 and 18 months old) cultured in ponds in Marennes-Oléron Bay (Atlantic coast, France) are reported. Two ponds were loaded with two different initial oyster biomasses in order to obtain different food conditions. The growth of oysters was different in the two ponds which corroborated the effectivences of attaining different food conditions. AEC level was different depending on the pond and was therefore related to food availability per unit oyster biomass. Well-fed oysters exhibited greater AEC values than poorly-fed oysters, throughout thc study. Information on nutritional situations for wild or cultured populations can therefore be obtained by AEC. In cach pond, the seasonal AEC variations were...
