AbstractThe factors affecting lipid and fatty acid composition of copepod Calanus sinicus in the Yellow Sea (YS) and the East China Sea (ECS) were examined in this study. In spring, there were significant differences between these two regions for both environmental conditions and food availability. Such regional difference significantly influenced the lipid and fatty acid profiles of C. sinicus. Our results show that C. sinicus has a higher lipids content in ECS, especially for wax ester and triglyceride lipids, indicating a more active and efficient predation. According to BIO-ENV analysis, the variation of lipids profiles may be influenced majorly by water temperature. Moreover, the fatty acids (FAs) profiles of C. sinicus were also different between YS and ECS, especially in the four major contributors, C22:1 omega 11, eicosapentaenoic acid (EPA), docosahexenoic acid (DHA), and C20:1 omega 9. The considerable amounts of self-biosynthesized FAs of herbivorous copepod (C22:1 omega 11 and C20:1 omega 9) and low DHA/EPA ratio may indicate that C. sinicus in ECS feed mainly on phytoplankton comparing to those in YS. The fatty acid profiles of C. sinicus were affected by the differences in food availability.
