“…Polyunsaturated fatty acids (PUFAs) play important roles in bivalve growth and development [31,51]. DHA has been shown to be integral in maintaining the membrane structure and functional integrity of tissues, and EPA has been shown to play a vital role in growth [52,53]; more importantly, as bivalves have limited ability to synthesize these FAs, they must be provided through their diet [25,54,55].…”

The sunray venus (sunray) clam, Macrocallista nimbosa, is an alternative clam species reared in hard clam hatcheries in Florida. Current feeding practices follow those used for hard clam culture. This study aimed to identify whether a hard clam bi-algal Tisochrysis lutea and Chaetoceros neogracile diet was an optimal diet for post-set sunray clams or whether other microalgal dietary combinations could improve production. Six dietary bi-, tri-, or tetra-algal combinations consisting of four microalgae species (Tisochrysis lutea, Diacronema lutheri, Chaetoceros neogracile, and Thalassiosira weissflogii) were fed for 6 weeks; the growth, survival, and fatty acid profiles of post-set clams were evaluated. Clams fed equal proportions of T. lutea, D. lutheri, C. neogracile, and T. weissflogii had higher growth, while those fed equal proportions of T. lutea and C. neogracile had higher survival. The poorest-performing diet consisted solely of diatoms. A contrasting polyunsaturated fatty acid (PUFA) profile was found in post-set clams fed flagellate- or diatom-only diets. Clams fed the bi-algal flagellate diet had a higher percentage of docosahexaenoic acid (DHA) but a lower percentage of (n-6) PUFA, whereas those fed the bi-algal diatom diet had a higher percentage of arachidonic acid (ARA) and eicosapentaenoic acid (EPA) but a lower percentage of DHA. The percentages were similar and neither very high nor very low in clams fed the remaining dietary treatments. The results of this study show that sunray venus post-set clams can be successfully produced when fed a typical hard clam bi-algal flagellate and diatom diet, but they indicate that growth may be accelerated by the addition of other microalgae species.

“…As a result of the hydrolysis of lipids during digestion, much of the nutritional value of lipids is related to the FA profile (Sánchez-Lazo & Martínez-Pita 2014). The n -3 PUFA, DHA, and EPA are vital for growth and larval development and, as bivalves are thought to be unable to synthesize these FA, they must be acquired through diet (Soudant et al 1998, Patil et al 2007, Kapranova et al 2019), although there is some evidence to suggest that low levels of synthesis may occur based on studies with Pacific oysters (Waldock & Holland 1984). Both DHA and EPA are needed to maintain cell membrane structure and tissue integrity and are important for membrane function (Marty et al 1992, Hendriks et al 2003, Gagné et al 2010).…”

“…In late August-early September, an adult mussel throws larvae (glochidia) into the water column [21,26,[28][29][30]77]. Mollusks can actively accumulate lipids during gametogenesis [78,79]. The lipid content in the mantle of the female bivalve M. galloprovincialis increases during the reproductive cycle [73,74].…”

Lipid Profile of the Freshwater Pearl Mussel Margaritifera margaritifera Inhabiting Different Biotopes of the Lake-River System of the Kem River, White Sea Basin

The freshwater pearl mussel Margaritifera margaritifera is considered to be the most rapidly declining species of freshwater bivalve, whereas its colonies in rivers of the White Sea Basin remain the most numerous in the world. The lipid profiles of mantle, muscle (foot), and digestive gland tissues of the freshwater pearl mussel from the Kem, Ukhta, and Vozhma Rivers in autumn (end of September, early October) were studied using high performance thin-layer chromatography. The highest total lipid [TL] content was found in the digestive gland. Cholesterol esters, non-esterified fatty acids, phospholipids, and cholesterol were the dominant lipids in all studied tissues. The reduced triacylglycerol content in the mussels was associated with its utilization during the spawning period. The colony of the freshwater pearl mussel inhabiting the Vozhma River was distinguished by higher TL content in the mantle and digestive gland. Data on the size-age characteristics of mollusks from the Kem, Ukhta, and Vozhma Rivers and the relationship between the structural and storage lipid content and size-age parameters are discussed. The results are important for different conservation strategies of endangered species, such as the freshwater pearl mussel, especially in ecological monitoring based on evaluation of the physiological and biochemical state of mollusks and rare natural colonies.
