Furthermore, the same results was also observed in Argopecten ventricosus (Lora-Vilchis and Doktor, 2001), Pinctada imbricata (Lodeiros et al, 2016), and Ostrea edulis (Laing and Millican, 1986. ) Although in other species of mollusk, I. galbana showed better result in inducing growth of M. mercenaria (Wikfors et al, 1992) and C. virginica (Epifanio, 1979).…”

A feeding trial was conducted to assess the potential of four species of marine microalgae as diets for green mussel Perna viridis spats. Species of algae tested were: Isochrysis galbana, Tetraselmis tetrahele, Chaetoceros calcitrans, and Skeletonema tropicum. Growth, survival and filtration rates were assessed. Highest growth rate was observed in spats fed with C. calcitrans followed by I. galbana and T. tetrahele, and S. tropicum, respectively. No significant differences in the survival of spats was observed in all feeding treatments. Further, filtration rate as factor affecting bivalve filter-feeding behavior was also measured. Highest filtration rate was observed in groups fed with C. calcitrans and I. galbana. The present study provides valuable information on the suitable diets for the nursery culture of green mussel spats. Furthermore, our results provide a basis for developing a better feeding strategy for the production of mussel spats in captivity.

“…Early studies recognised lipids to be the main energy stores for bivalves up to 6 months post-settlement [25,26]. Since then, evaluating the lipid composition of diets and juveniles gained a central importance on bivalve nutrition studies with examples available for clams [27][28][29][30][31][32][33], scallops [34][35][36], oysters [37][38][39][40][41][42] and mussels [19,[43][44][45][46]. Other than protein and carbohydrate composition, the nutritional properties of shellfish diets strongly depend on the essential PUFA (arachidonic acid-20:4n-6, AA; eicosapentaenoic acid-20:5n-3, EPA; docosahexaenoic acid-22:6n-3, DHA) content [47].…”

Lipidomics analysis of juveniles’ blue mussels (Mytilus edulis L. 1758), a key economic and ecological species

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.

“…Suitable particle sizes for P. f. martensii and P. maxima are 2.5-10 μm and >4 μm, respectively (Yukihira and Klumpp, 1999;Tomaru et al, 2002). Although the microalgae of all sizes used in this study could be easily ingested, smallsize microalgae [I. galbana (I, ~5.51 μm) and C. muelleri (C, ~4.5 μm)] were more suitable for these two pearl oyster species 2002; Lodeiros et al, 2017). In our study, the crude protein and lipid in the I and C groups were higher than those in the P group, which indicated that more nutrients are obtained by pearl oysters from I and C treatments.…”

Pinctada fucata martensii and P. maxima are two main traditional pearl oyster species that can produce seawater pearls. Our previous study showed a higher clearance rate (CR) and growth performance in P. f. martensii than in P. maxima fed with Isochrysis galbana. In this study, the P. f. martensii and P. maxima juveniles of two sizes (large and small) were fed with six different microalgae diets [I. galbana (I), Platymonas subcordiformis (P), Chaetoceros muelleri I, I+P, I+C, and P+C] to evaluate the differences in growth, feeding, and metabolism between two pearl oyster species. After 60 d of the rearing period, P. f. martensii and P. maxima fed with mixed microalgae showed a significantly higher relative growth rate (RGR) than those fed with single microalgae (P< 0.05). The RGRs were significantly higher in P. f. martensii than those in P. maxima fed with the same diets (P< 0.05). The RGRs showed a decreasing tendency with the growth in both pearl oyster species. The CRs of pearl oysters fed with mixed microalgae were significantly higher than those fed with single microalgae (P< 0.05), and the CRs of P. f. martensii were significantly higher than those of P. maxima fed with the same diets (P< 0.05). Significantly lower respiration rates (RRs) were observed in small-size P. f. martensii groups fed with I, P, and I+P diets and all large P. f. martensii groups compared to P. maxima fed with the same diets (P< 0.05). Higher activities of amylase, cellulase, lipase, and pepsin in P. f. martensiiwere observed compared to P. maxima fed with the same diets at two sizes. The pepsin activities in P. maxima decreased with the growth, while there were no consistent pepsin activities of P. f. martensii with the growth. The carbonic anhydrase activities in P. maxima were significantly higher than those in P. f. martensii fed with the same diets (P< 0.05). The carbonic anhydrase activities were highest in the I+C diet group, followed by C+P and I+P, I, C, and P groups. Significant differences were observed among different diet groups in the same pearl oyster species (P< 0.05). Our results suggest that the lower CR and activities of digestive enzymes and higher RRs and activities of carbonic anhydrase may cause a lower growth rate of P. maxima compared to P. f. martensii.
