“…() also observed that 18:2ω6 was probably elongated to 20:2ω6 in R. philippinarum spat, given that 20:2ω6 was absent in the diet. Sánchez‐Lazo & Martínez‐Pita () also suggested that bivalves could synthesize 18:4ω3 and 20:2ω6 from precursors.…”

Fatty acid composition of female and male clams (Ruditapes philippinarum): energy intake and temperature reliance

We analysed the effect of temperature, coupled with food ingestion rate (IR), on the fatty acid (FA) profile of female and male clams conditioned in two groups: L (low IR at 14 and 18°C) and H (high IR at 18 and 22°C). Significant differences for group L, both 18L and 14L with low IR and slow gonadal development, owed to differences in energy balance between 18L clams (negative energy balance) and 14L clams (positive energy balance). Plasmalogens (DMA 18:0) and non-methylene-interrupted FAs might protect against reactive oxygen species and preserve the integrity of the cell membranes during food stress in 18L clams. Differences in composition for group H, both 18H and 22H with high food intake, positive energetic balance and complete and similar gonadal occupation index (GOI), probably owed to the greater energy levels at 18°C than at 22°C. Clams at 22°C H increased the oxidation of short-chained PUFA 18:3x3 and 18:3x6 to maintain the same GOI as 18H clams. Regarding the sexual differences, the greater accumulation of 20:5x3 and 20:4x6 in females might be related with oocyte maturation and release during spawning, while the greatest levels of 22:6x3 in males might be involved in spermatocyte membranes synthesis.

“…In fact, there have been recommendations that a mixed algae diet for bivalve larvae should be comprised of at least both a diatom and flagellate (Rico‐Villa et al . ; Sánchez‐Lazo & Martínez‐Pita ). Although P. margaritifera larvae are reportedly often fed with T. Iso in combination with other species such as Pavlova salina or Chaetoceros simplex (Southgate & Beer ; Doroudi et al .…”

Effect of different dietary microalgae combinations on growth and survival of black-lip pearl oyster (Pinctada margaritifera) larvae and the feasibility of replacing microalgae with a dietary lipid emulsion

et al. 2016

A 10-day experiment was performed to examine different mono, binary and ternary dietary combinations on survival and growth of D-shaped and umbone black-lip pearl oyster, Pinctada margaritifera, larvae. The three tropical microalgae species were the flagellate Isochrysis galbana clone T. Iso (CS-177) and diatoms Chaetoceros calcitrans (CS-178) and Chaetoceros muelleri (CS-176) which were fed to D-shaped and umbone larvae at a density of 7000 and 14 000 cells mL À1 , respectively. A second experiment was performed to investigate the feasibility of replacing T. Iso with a lipid emulsion for both D-shaped and umbone larvae for 10 and 12 days, respectively. The treatments included only T. Iso, unfed and lipid emulsion to substitute T. Iso at levels of 10% (LIP10), 30% (LIP30) and 100% (LIP100). In the first experiment, results showed that a monospecific diet of T. Iso led to significantly higher (P < 0.05) survival and growth of D-shaped larvae than all the other treatments. Meanwhile, D-shaped larval survival was significantly lower when only fed C. calcitrans as well as growth for those fed C. calcitrans or in combination with C. muelleri. However, for umbone larvae, survival and growth were significantly higher when fed a binary combination of T. Iso and C. muelleri or the ternary combination of T. Iso, C. muelleri and C. calcitrans compared with all other treatments. For the second experiment, results showed that with increasing lipid emulsion replacement, survival of both D-shaped and umbone larvae significantly decreased (P < 0.05); however, the LIP100 treatment was not significantly different (P > 0.05) from the unfed treatment. For D-shaped larvae, no significant growth difference was detected (P > 0.05) between the T. Iso and LIP10 fed treatments while for umbone larvae, the T. Iso, LIP10 and LIP30 were not significantly different (P > 005). These results indicate that microalgae combinations appear more necessary for later staged P. margaritifera larvae. In addition, the use of a lipid emulsion appeared to provide some nutrition to the larvae, although more research should be conducted to improve the use of such replacements.

“…For example, the Haptophyceae I. galbana was a favourable diet for E. ziczac larvae (see Figs and ), and it supports good survival and growth for the larvae of some clams (Fernández‐Reiriz et al . ), scallops (Velasco & Barros ) and mussels (Sánchez‐Lazo & Martínez‐Pita ). In contrast, it was an inadequate diet for Crassostrea spp.…”
