Abstract

Lipid classes and fatty acids of triacylglycerol and phospholipid fractions of introduced Crassostrea gigas from El Grove were analysed andcompared for 16 months. The fluctuations in the lipid content were correlated to the phytoplankton concentration and sexual cycle. The seasonal variations in lipid content were due largely to changes in triacylglycerols, the major lipid class. Phospholipids and sterols followed a similar seasonal cycle with minor oscillations. Polyunsaturated fatty acid (PUFA) was negatively correlated with temperature and showed a pattern similar to n-3 series with great fluctuations, whereas the n-6fatty acids had minor fluctuations throughout the year and showed no clear seasonal variation. The content of 20:5n-3 was higher than 22:6n-3 in triacylglycerols and similar in phospholipids. The 20:4n-6 was the major fatty acid of n-6 series and correlated negatively with condition index, temperature and chlorophyll a in the phospholipid fraction. The maturity index correlated positively with 18:4n-3 from phospholipids.
