ABSTRACT Variations in biochemical composition and lipid classes in relations to the gametogenic cycle were studied in digestive gland, labial palps and gonad in the Pacific oyster Crassostrea gigas from the Western Atlantic coast of France over 1 y. Variations in the weight of the soft body parts, gonad development and spawning depended on environmental conditions, mainly on nutrients availability. The main energy reserve is the glycogen, showing a marked seasonal variability in all tissues studied this component increased in the digestive gland during the phytoplankton blooms and was rapidly transferred and accumulated in labial palps and gonad during stages IIID-0; ...
