“…Another polar lipid class highly present in MONO resulted LPC. LPC are products of PC metabolism, formed by the cleavage of a FA residual in position sn-1 or sn-2 by a phospholipase [97]. Increasing in LPC could be connected with the lower nutritional value of M. subterranean and the attempt to produce energy by polar lipid catabolism in the juvenile mussels.…”

Blue mussels (Mytilus edulis L. 1758) are important components of coastal ecosystems and in the economy of rural and coastal areas. The understanding of their physiological processes at key life stages is important both within food production systems and in the management of wild populations. Lipids are crucial molecules for bivalve growth, but their diversity and roles have not been fully characterised. In this study, traditional lipid profiling techniques, such as fatty acid (FA) and lipid class analysis, are combined to untargeted lipidomics to elucidate the lipid metabolism in newly settled spat fed on a range of diets. The evaluated diets included single strains treatments (Cylindrotheca fusiformis CCAP 1017/2 -CYL, Isochrysis galbana CCAP 927/1-ISO, Monodopsis subterranean CCAP 848/1 -MONO, Nannochloropsis oceanica CCAP 849/10-NANNO) and a commercial algae paste (SP). Spat growth was influenced by the diets, which, according to their efficacy were ranked as follows: ISO>NANNO/CYL>SP>MONO.

“…The hepatopancreas is a potential source of 1,3‐specific lipases hydrolysing long‐chain triacylglycerols in scallops (Itabashi & Ota 1994). PLA 2 activity in bivalves is mainly present in the digestive glands with much lower activities in the other tissues (Sajiki & Taguchi 1995).…”

Activities of the digestive enzymes neutral lipase and phospholipase A2 were present in 2‐mm scallop juveniles, indicating an endogenous ability to digest lipids. When determined in the dietary microalgae, lipolytic activities of both enzymes differed significantly, being highest in Isochrysis galbana and Tetraselmis sp. and lowest in Chaetoceros mülleri. Compared with the activities found in scallop juveniles, enzyme activities from the microalgae were rather low and did not seem to contribute considerably to their digestive process. However, ingested algae seemed to have a regulating effect on the phospholipase activity in scallops, as juveniles fed I. galbana had a significantly lower activity than juveniles of the other treatments. No such effect was evident for neutral lipase, indicating different regulation mechanisms for both enzymes. Dietary effects on digestive enzymes in scallop juveniles should be considered when choosing new potential algal species as feed or for future formulation of artificial diets.

Blue mussels (Mytilus edulis L.) are important components of coastal ecosystems functioning through benthopelagic coupling and ecosystem engineering. At the same time, mussel production is central in the economy of coastal areas. Therefore, understanding their nutritional, physiological and metabolic processes at key life stages is important for their management, both within food production systems and in wild populations.Lipids are crucial molecules for bivalve growth, but their diversity and roles have been considered from fatty acid (FA) perspective. In this paper, we applied lipidomics to bivalve nutrition. Lipidomics provides a holistic perspective on lipid patterns; by examining the lipidome, important physiological information can be acquired. Here, we use controlled laboratory experiments to elucidate the responses to changes in the diet of newly settled mussels juveniles, one of the most critical life stages. The diets considered in this study are single strains diet of Cylindrotheca fusiformis CCAP 1017/2 – CYL, Isochrysis galbana CCAP 927/1– ISO, Monodopsis subterranean CCAP 848/1 – MONO, Nannochloropsis oceanica CCAP 849/10– NANNO and a commercial algae paste –SP.The diets had a significant effect on spat GR and WI, and according to their efficacy resulted ranked as follows: ISO>NANNO/CYL>SP>MONO. Spat FA composition and neutral lipid content (principally triacylglycerols - TG), were influenced by the diets. Furthermore, untargeted lipidomics also showed shifts in several phospholipid species, with changes related to the essential PUFA available from the diet. TG content, neutral lipids and several TG and FA species were correlated (Spearman R2>0.8 FDR p<0.05) with spat WI, suggesting their possible application as markers of mussel juvenile condition. The availability of dietary essential PUFA deeply modified the spat lipidome both for neutral and for polar lipids. This change in the lipidome could have major impacts on their ecology and their production for food.
