“…The highest phospholipid content in this study from the three areas was lower than the maximum reported in other studies[Dagorn et al, 2016;Liu et al, 2020;Pogoda et al, 2013]. Phospholipids are synthesized and accumulated as a response to low water salinity and freezing temperatures[Fokina et al, 2018]. This might explain the low phospholipid values in this study in comparison to other areas.…”

The lipid profiles of the oyster Crassostrea gigas cultured in Khanh Hoa coast at three locations and harvested in different months throughout the year were compared. Seasonal and locational changes in total lipid (TL) content, phospholipid content, free fatty acid content, fatty acid (FA) composition, and thrombogenicity index were found. The total lipid content and n-3/n-6 ratio in oysters from Ninh Hoa were higher compared to those from Cam Lam and Van Ninh. For oyster from all three farming areas, the total lipid content was the lowest during the two spawning seasons (May and September). Lipids from C. gigas were separated into neutral and polar lipid fractions using silica gel column chromatography. The amount of neutral lipids recovered from the oyster muscle was significantly higher than that of the polar lipids. The FA composition showed that C. gigas was abundant in saturated fatty acids (30.89-39.16 g/100 g TL), followed by polyunsaturated fatty acids (28.13-35.88 g/100 g TL), and monounsaturated fatty acids (19.32-23.75 g/100 g TL). The dominant polyunsaturated fatty acids of oysters from the three farming areas were eicosapentaenoic acid (9.09-13.77 g/100 g TL) and docosahexaenoic acid (6.71-16.47 g/100 g TL). Based on the present findings, it can be concluded that the Pacific oyster C. gigas cultured in Khanh Hoa, Vietnam is a promising source of highly nutritious exploitable lipids.

“…Seasonal variability was observed in Astarte moerchi and Hiatella arctica , which displayed an ~35% decrease in lipid content between winter and summer. The seasonal decrease in lipid content observed for A. moerchi and H. arctica may reflect (1) a strong allocation of energy reserves (i.e., egg production and spawning) between these two sampling periods toward reproduction (Amiraux et al., 2021 ; Birkely et al., 2003 ; Fokina et al., 2018 ; Pazos et al., 1997 ) and/or (2) high mobilization of energy reserves to meet the energetic needs of bivalves in the face of low food availability and/or interruption of bivalve feeding during winter (Ahn et al., 2003 ; Mayrand et al., 2017 ; McMeans et al., 2015 ). The mobilization of energy reserves for egg production usually involves a transfer of EFAs (especially 20:5ω3 and 22:6ω3) from the digestive glands to the gonads, resulting in a drastic decrease of these fatty acids in the digestive glands after reproductive investment (Leroy et al., 2013 ; Martínez‐Pita et al., 2012 ).…”

Seasonal lipid dynamics of four Arctic bivalves: Implications for their physiological capacities to cope with future changes in coastal ecosystems

The Arctic is exposed to unprecedented warming, at least three times higher than the global average, which induces significant melting of the cryosphere. Freshwater inputs from melting glaciers will subsequently affect coastal primary production and organic matter quality. However, due to a lack of basic knowledge on the physiology of Arctic organisms, it remains difficult to understand how these future trophic changes will threaten the long‐term survival of benthic species in coastal habitats. This study aimed to gain new insights into the seasonal lipid dynamics of four dominant benthic bivalves (Astarte moerchi, Hiatella arctica, Musculus discors, and Mya truncata) collected before and after sea ice break‐up in a high‐Arctic fjord (Young Sound, NE Greenland). Total lipid content and fatty acid composition of digestive gland neutral lipids were analyzed to assess bivalve energy reserves while the fatty acid composition of gill polar lipids was determined as a biochemical indicator of interspecies variations in metabolic activity and temperature acclimation. Results showed a decrease in lipid reserves between May and August, suggesting that bivalves have only limited access to fresh organic matter until sea ice break‐up. The lack of seasonal variation in the fatty acid composition of neutral lipids, especially essential ω3 fatty acids, indicates that no fatty acid transfer from the digestive glands to the gonads occurs between May and August, and therefore, no reproductive investment takes place during this period. Large interspecies differences in gill fatty acid composition were observed, which appear to be related to differences in species life span and metabolic strategies. Such differences in gill fatty acid composition of polar lipids, which generally influence metabolic rates and energy needs, may imply that not all benthic species will be equally sensitive to future changes in primary production and organic matter quality in Arctic coastal habitats.

The lipid composition of blue mussels Mytilus edulis L. living under different environmental conditions (in the intertidal zone and in aquaculture) was studied to detect origin-related differences in seasonal modifications of lipids, and their fatty acid composition in gills and digestive glands. In early May, the gills and digestive glands of intertidal mussels contained higher amounts of total lipids, chiefly phospholipids and sterols, which appear to perform a protective function as maintenance of membrane integrity. Seasonal modifications in lipid composition of both intertidal and aquaculture mussels were related to environmental factors (mainly low temperature), reproductive processes and food availability. We show that seasonal changes in membrane lipid composition of both intertidal and aquaculture mussels reflect the process of membrane lipid remodelling (namely changes in phosphatidylethanolamine proportion and in the fatty acid composition of phospholipids) required for homeoviscous adaptation in low-temperature conditions. In particular, the unsaturation index and chain fluidity index of phospholipids increased in gills and digestive glands of mussels collected in early May and in November. Similar seasonal changes in the triacylglycerol levels and its fatty acid composition were observed in gills and digestive glands of both intertidal and aquaculture mussels collected in late May and August.
