Abstract

Bivalves are a good source of lipid such as fatty acids and phospholipids, but little is known about how dietary fatty acids affect the fatty acid and phospholipid profiles of bivalves. In this study, the effects of dietary fatty acids on growth, oxidation status, fatty acid and phospholipid profiles of razor clams were investigated by employing microencapsulated feeds containing different oils (fish oil, FO; soybean oil, SO; flaxseed oil, FLO; coconut oil, CO; arachidonic acid-enriched oil, AO; olive oil, OO; and palm oil, PO). The results showed that the final weight of the razor clams fed FO enriched with eicosapentaenoic acid (EPA, C22:5n-3) and docosahexaenoic acid (DHA, C22:6n-3) was significantly higher than that of all other treatment groups. The final weight of the razor clams in the SO group was significantly higher than that in AO, OO and PO groups. The superoxide dismutase and catalase activity of the razor clams in the AO group was significantly higher than that in the OO group. Fatty acid profiles of the razor clams reflected dietary fatty acid composition. A total of 410 phospholipids were found in razor clams. Among them, phosphatidylcholine and phosphatidylethanolamine were the most abundant phospholipids. In addition, dietary fatty acids significantly altered the fatty acid composition of phospholipids. Our findings revealed that addition of certain amounts of EPA and DHA to the feed significantly promoted the growth rate of the razor clams. Moreover, the EPA and DHA content in the razor clams and their proportion in phospholipids increased significantly.

期刊介绍： Comparative Biochemistry & Physiology (CBP) publishes papers in comparative, environmental and evolutionary physiology. Part B: Biochemical and Molecular Biology (CBPB), focuses on biochemical physiology, primarily bioenergetics/energy metabolism, cell biology, cellular stress responses, enzymology, intermediary metabolism, macromolecular structure and function, gene regulation, evolutionary genetics. Most studies focus on biochemical or molecular analyses that have clear ramifications for physiological processes.
