Abstract

The lipid and fatty acid (FA) contents of muscle, gonad and digestive glands (DG) of Jade Tiger hybrid abalone were studied over the four seasons. Higher contents of total lipid and saturated fatty acids (SFA) were found in summer from muscle. For gonad the higher total lipid content was found in summer and spring whereas the SFA content peaked in summer only. For DG the higher contents of total lipid and SFA were recorded in all seasons except autumn. Winter samples showed significantly higher content of PUFA in all three types of tissue. High contents of eicosapentaenoic acid (EPA, 20:5 n−3), docosapentaenoic acid (DPA, 22:5 n−3) and docosahexaenoic acid (DHA, 22:6 n−3) were recorded in winter from muscle, although no marked variations were observed from gonad. For DG the high content of DHA was also observed in winter whilst EPA and DPA maintained high levels in all seasons except summer.
