“…Our δ 13 C tissue isotopic data showing sole utilization of maternally derived carbon during the formation of the initial D‐hinge shell (Figure b) confirms previous findings on the role of endogenous energy sources for early larval bivalves [ Gallager and Mann , ; Sanchez‐Lazo and Martinez‐Pita , ]. The depletion of larval energy reserves (primarily lipids) following D‐hinge shell formation (Figure b and c), and the δ 13 C tissue trend (Figure b) highlights that the energy available for embryogenesis and D‐hinge shell growth is limited by the available maternally‐derived energy.…”

[1] Acidified waters are impacting commercial oyster production in the U.S. Pacific Northwest, and favorable carbonate chemistry conditions are predicted to become less frequent. Within 48 h of fertilization, unshelled Pacific oyster (Crassostrea gigas) larvae precipitate roughly 90% of their body weight as calcium carbonate. We measured stable carbon isotopes in larval shell and tissue and in algal food and seawater dissolved inorganic carbon in a longitudinal study of larval development and growth. Using these data and measured biochemical composition of larvae, we show that sensitivity of initial shell formation to ocean acidification results from diminished ability to isolate calcifying fluid from surrounding seawater, a limited energy budget and a strong kinetic demand for calcium carbonate precipitation. Our results highlight an important link between organism physiology and mineral kinetics in larval bivalves and suggest the consideration of mineral kinetics may improve understanding winners and losers in a high CO 2 world.

Influence of one selectedTisochrysis luteastrain rich in lipids onCrassostrea gigaslarval development and biochemical composition

Effects of a remarkably high overall lipid Tisochrysis lutea strain (T+) upon gross biochemical composition, fatty acid (FA), sterol and lipid class composition of Crassostrea gigas larvae were evaluated and compared with a normal strain of Tisochrysis lutea (T) and the diatom Chaetoceros neogracile (Cg). In a first experiment, the influence of different single diets (T, T+ and Cg) and a bispecific diet (TCg) was studied, whereas, effects of monospecific diets (T and T+) and bispecific diets (TCg and T+Cg) were evaluated in a second experiment. The strain T+ was very rich in triglycerides (TAG: 93-95% of total neutral lipids), saturated FA (45%), monounsaturated FA (31-33%) and total fatty acids (4.0-4.7 pg cell À1 ). Larval oyster survival and growth rate were positively correlated with 18:1n-7 and 20:1n-7, in storage lipids (SL), and negatively related to 14:0, 18:1n-9, 20:1n-9, 20:4n-6 and trans-22-dehydrocholesterol in membrane lipids (ML). Surprisingly, only the essential fatty acid 20:5n-3 in SL was correlated positively with larval survival. Correlations suggest that physiological disruption by overabundance of TAG, FFA and certain fatty acids in larvae fed T+ was largely responsible for the poor performance of these larvae. 'High-lipid' strains of microalgae, without regard to qualitative lipid composition, do not always improve bivalve larval performance.

“…To maintain the long‐term sustainable development and competitive advantages of this industry, the development of techniques that could provide progenies without seasonal limitations or assist the genetic improvement programmes has become the key interests in recent years (Pettersen et al . ; Sánchez‐Lazo & Martínez‐Pita ,b). Gamete cryopreservation is one of the effective techniques that could achieve these goals and has been well advanced in Pacific oysters Crassostrea gigas (Adams, Smith, Roberts, Janke, King, Tervit & Webb ; Zhang, Li, Clarke & Li ) and abalone (Liu, Li, Xu, Robinson & Qin ; Zhu, Li, Qu, Liu & Clarke ).…”

In this study, a non-programmable freezing technique has been developed with the strip spawned blue mussel (Mytilus galloprovincialis) sperm. The key parameters optimized including (1) cryoprotectant agents (CPAs); (2) cooling temperature; (3) thawing temperature; (4) sugar and amino acid supplementation and (5) sperm to egg ratio. The fertilization rate and/or integrity of plasma membrane and acrosome were used as sperm quality assessment indicators. The highest post-thaw sperm fertilization rate of 95% was achieved, when sperm were cryopreservated in 8% dimethyl sulfoxide at 7.8 cm above the liquid nitrogen surface and thawed in a 60°C seawater bath. The addition of glucose, sucrose or trehalose in dimethyl sulfoxide did not, whereas 0.8% glycine did significantly improve the post-thaw sperm fertilization rates. The fluorescent evaluation has demonstrated that the addition of glycine significantly improved the post-thaw sperm acrosome integrity, revealing a positive role of glycine in the improvement of postthaw sperm quality in blue mussels.
