“…Indeed, the ability to biosynthesize 20:3 NMI FA from the precursor 18:2n-6 and to substitute ARA in the membrane phospholipids may represent an important advantage for organisms exposed to fluctuating temperatures which requires membrane fluidity adaptations. Indeed, it was shown that the unusual double bond position in 20:3 NMI FA causes a melting point shift of about 10 C lower (Zakhartsev et al, 1998;Pirini et al, 2007) and this could partly explain the wide geographical distribution of P. lividus.…”

A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT AbstractThe effects of dietary fatty acids on the composition of Paracentrotus lividus gonads were investigated to determine whether dietary inputs affect their relative abundance during gametogenesis. Egg and embryo FA compositions were compared with that of mature gonads to understand how maternal FA are transferred to the offspring. Urchins were fed an experimental pellet diet in comparison to brown kelp (Laminaria digitata). FA profiles of diets, gonads, eggs and embryos revealed the presence in gonads of FA that were absent in the diets and/or higher contents of some long-chain polyunsaturated fatty acids (LC-PUFA). Moreover, some unusual FA, such as non-methylene interrupted (NMI), were found in gonads, eggs and embryos, but not in the diets, suggesting that P. lividus may be capable of synthesizing these FA and accumulating them in the eggs. A description of gonad FA profiles during gametogenesis is reported for the first time and data suggest that eicosapentaenoic and docosahexaenoic acids are accumulated during gametogenesis, while arachidonic acid is highly regulated and is the only LC-PUFA clearly accumulated into the eggs along with NMI. Further studies are required to determine if maternal provisioning of FA has the potential to influence sea urchin production outputs and increase hatchery profitability.

“…Although we specifically analysed the PL fractions, where NMI FA are believed to accumulate (Klingensmith, 1982;Pirini et al, 2007), the amounts of all the NMI FA identified were generally low, and only relatively higher contents were detected for Δ5,11 20:2 in nephridium (1.8 %) and its potential elongation product Δ7,13 22:2 in male gonad (2.2 %).…”

“…This suggests that adult A. purpuratus possess high homeostatic capabilities that minimise the effect of exogenous FA on phospholipid composition. Presumably, A. purpuratus can modulate the incorporation of FA even if the dietary supply is high, as observed for other bivalves (Pirini et al 2007;Delaporte et al 2003;Soudant et al 1998). Even though we have not identified the exact mechanism(s) and factor(s) affecting mitochondrial capacities, differences between the phytoplankton in the content of other compounds such as vitamins or antioxidants could have led the functional capacities of mitochondria to differ.…”

-We examined whether escape response performance and mitochondrial capacities could reveal differences created by feeding scallops, Argopecten purpuratus, mono-specific algal diets composed of either Chaetoceros calcitrans or Isochrysis galbana (variety T. iso) hereafter T. iso. Before and after feeding scallops with these diets, we assessed force production in vivo to evaluate escape response performance (initial and repeat). We measured oxidative capacities of mitochondria isolated from the adductor muscle and from the male and female portions of the gonad. Initial escape response performance was reduced more by the C. calcitrans diet than by the T. iso diet. Repeat escape responses, which require aerobic recuperation, were reduced by both treatments. The oxidative capacity of mitochondria isolated from muscle and female gonad was markedly lower in scallops fed C. calcitrans than in those fed T. iso. Flux through complex I-IV and through complex IV was also lower in mitochondria from muscle of scallops fed C. calcitrans than in those fed T. iso. Muscle aerobic capacity, assessed by citrate synthase activity, was lower in scallops fed C. calcitrans than in those fed T. iso. Despite the marked differences in fatty acid (FA) composition of the algal diets, the FA composition of mitochondrial phospholipids differed little between scallops fed C. calcitrans and those fed T. iso. Both escape response behaviour and mitochondrial capacities changed with feeding mono-specific diets. The simplicity of measurements of scallop escape responses suggests this as a practical means of evaluating the status of scallops for the two monoalgal diets tested.
