“…Of particular interest is the finding of extensive bioaccumulation of 6 docosapentaenoic acid linked to improved growth in scallop species [37][38][39] and cod [40] during early ontogeny, suggesting that this is a fourth PUFA which may be essential in marine fauna. 6DPA may play an important structural role in membranes and/or may be a precursor of bioactive docosanoids.…”

“…It is interesting that this is the same question being asked in the field of aquaculture nutrition in different ontogenetic stages of multiple species from several phyla. For example, dietary and tissue fatty acids and sterols have been measured to determine incorporation efficiencies or enrichments and depletions in yellowtail flounder [121] and sea scallops [37,78]. Such data may help in the application of QFASA to fish and primary consumers; however, the breadth of species and differences in lipid metabolism in the lower food web may make quantitative estimates of fatty acid flow through the lower food web difficult.…”

Lipids provide the densest form of energy in marine ecosystems. They are also a solvent and absorption carrier for organic contaminants and thus can be drivers of pollutant bioaccumulation. Among the lipids, certain essential fatty acids and sterols are considered to be important determinants of ecosystem health and stability. Fatty acids and sterols are also susceptible to oxidative damage leading to cytotoxicity and a decrease in membrane fluidity. The physical characteristics of biological membranes can be defended from the influence of changing temperature, pressure, or lipid peroxidation by altering the fatty acid and sterol composition of the lipid bilayer. Marine lipids are also a valuable tool to measure inputs, cycling, and loss of materials. Their heterogeneous nature makes them versatile biomarkers that are widely used in marine trophic studies, often with the help of multivariate statistics, to delineate carbon cycling and transfer of materials. Principal components analysis has a strong following as it permits data reduction and an objective interpretation of results, but several more sophisticated multivariate analyses which are more quantitative are emerging too. Integrating stable isotope and lipid data can facilitate the interpretation of both data sets and can provide a quantitative estimate of transfer across trophic levels.

The development of swift's scallop Chlamys swiftii, reared in the laboratory, has been examined through the investigation of morphological characteristics in fertilized egg, larvae and juvenile. Eggs were fertilized with a dilute sperm solution to improve the survival of fertilized eggs. Developing larvae were maintained at a temperature of 16 ± 0.5℃ and salinity concentration of 33 ppt. We have investigated the fertilization rates and egg number spawned at several stimulating conditions such as sunlight exposure, air dry, seawater temperature rise (5℃) and seawater temperature rise (5℃) after exposure of air dry for spawning induction of swift's scallop Chamys swiftii. Stimulation treated with sunlight exposure and seawater temperature rise (5℃) have shown the spawning number of 700,000-900,000 and 700,000-800,000 per individual, respectively while stimulation treated with seawater temperature rise (5℃) after exposure of air dry have shown the high spawning number of 1,000,000-1,500,000 per individual. Survival rate of D-shaped larvae of swift's scallop put into the different seawater temperatures of 8℃, 1 2℃, 16℃, 20℃ and 24℃ has been 4.1%, 11.6%, 32.7%, 18.6% and 3.2%, respectively. Fertilized eggs with the diameter of 72 μm developed into trochophore larvae of 103 ± 3.8 μm shortly after 35 hours and to D larvae of 129 ± 10.4 μm shell length within 72 hours. It took 336 hours to become initial Umbo-stage larva of 145 ± 16.8 μm shell length. Post larvae, which have been 197 ± 13.6 μm shell length, spontaneously have settled in the attachment substances. It have required 528 hours from fertilized eggs to early attached juvenile to become initial juvenile size of 245 ± 15.8 μm shell length.

This study was done to examine the effect of several diets (Phytoplankton = PHY, Shellfish Diet 1800 = INS, Oil type = OTE, Powder type = PTE) on growth, survival rate and biochemical composition of scallop juvenile Patinopecten yessoensis. The highest survival rate were observed in PTE + PHY (90%). The highest shell length and shell height was observed in PHY and PTE + PHY diet (P > 0.05). The growth with PTE and OTE diet was the lowest in shell length and shell height (P < 0.05). On the other hand, the shell width and meat weight were highest in PHY and PTE + PHY, while the lowest in PTE and OTE (P < 0.05). The content of fatty acids such as DHA and n-3 PUFA levels was significantly higher in the juvenile fed on PTE + PHY than in those fed on PHY and INS alone. Also, the total protein ranged 55.5 to 65.2% in PHY + INS, while 44.8%, 47.9% in PTE and OTE respectively. The RNA and DNA contents were the highest in PHY and PTE + PHY, while the lowest in PTE and OTE (P < 0.05). RNA/DNA ratio significantly higher in juvenile with PHY + INS than those with PTE and OTE alone (P < 0.05). The combination of PTE + PHY could improve the growth and survival of scallop juvenile. Our results suggested that PTE could partially replace live algae in bivalve laval rearing.
