“…However, T-Iso algae, which provided high amounts of 22:6(n-3), allowed the maintenance of this PUFA in the haemocyte membranes of animals fed this diet. This impact of the lipid profile of the diet on haemocyte polar lipids agrees with other observations reported in other tissues or in larvae (Delaunay et al, 1993;Berntsson et al, 1997;Soudant et al, 1996bSoudant et al, , 1997Soudant et al, , 1999.…”

“…Many studies have shown that the quality of the algal diet affects the growth and development of molluscs such as the great scallop Pecten maximus (Delaunay et al, 1993;Soudant et al, 1996aSoudant et al, , 1998, C. gigas (Knauer and Southgate, 1997;Soudant et al, 1999Soudant et al, , 2000, O. edulis (Berntsson et al, 1997), R. decussatus (Albentosa et al, 1996;Fernández-Reiriz et al, 1998, 1999 and R. philippinarum (Caers et al, 1999). Dietary conditioning is also important in the resistance of the catfish Ictalurus punctatus to a stressful condition (Lingenfelser et al, 1995).…”

International audienceThe impact of diets upon the fatty acid composition of haemocyte polar lipids and consequently upon immune parameters has been tested in the oyster Crassostrea gigas and the clam Ruditapes philippinarum. Oysters and clams were fed each of three cultured algae: Chaetoceros calcitrans, which is rich in 20:5(n-3) and 20:4(n-6) and poor in 22:6(n-3) fatty acids; T-Iso (Isochrysis sp.), which is rich in 22:6(n-3) and deficient in 20:5(n-3) and 20:4(n-6); and Tetraselmis suecica, which is deficient in 22:6(n-3) and contains only small amounts of 20:5(n-3) and 20:4(n-6). Fatty acid composition of haemocyte polar lipids was greatly affected by the diet. Oysters and clams fed C. calcitrans maintained a higher proportion of 20:5(n-3) and 20:4(n-6) in their haemocyte polar lipids, while these polyunsaturated fatty acids decreased drastically for animals fed T-Iso. However, the T-Iso diet maintained 22:6(n-3) in haemocyte polar lipids of both species. Higher 20:5(n-3) and 20:4(n-6) contents in diets appeared to have a positive effect upon total haemocyte count, granulocyte percentage, phagocytic rate and oxidative activity of clam haemocytes. Similarly, a positive effect of 20:5(n-3) on oxidative activity of oyster haemocytes was observed but to a lesser extent than in clams. Interestingly, when oyster haemocytes are submitted to a stressful condition, a positive effect of a higher dietary 22:6(n-3) content on the phagocytic rate was noticed

“…Variability in maturation, egg laying, and larval and juvenile survival rates among batches may depend on many factors such as food, environmental factors and genetic background. Moreover, variation in the nutritive composition of the larvae between broods may influence development of larvae in various molluscs (Berntsson et al 1997;Marasigan and Laureta 2001;Gallager and Mann 1986;Soudant et al 1996;Wilson et al 1986). Teruel et al (2001) reported that a higher amount of essential nutrients in the artificial diets such as protein, lipid and the highly unsaturated fatty acids, e.g., 20:4n -6, 20:5n -3, 22:6n -3 in hatchery-bred donkey's ear abalone Haliotis asinina fed artificial diet alone and a combination of natural diet and artificial diet influenced the increased reproductive performance.…”

Differences in fatty acid composition of egg capsules from broodstock spotted babylon, Babylonia areolata, fed a local trash fish and formulated diet under hatchery conditions

This study is the first attempt to condition broodstock Babylonia areolata using formulated diets under hatchery conditions. Samples of spotted babylon egg capsules from broodstock fed either a formulated diet or a local trash fish, carangid fish (Seleroides leptolepis) for 120 days were analyzed for proximate composition and fatty acid composition. The formulated diet contained significantly higher levels of arachidonic acid (20:4n -6; ARA), eicosapentaenoic acid (20:5n -3; EPA) and docosahexaenoic acid (22:6n -3; DHA) than those of the local trash fish. The formulated diet also had significantly higher ratios of DHA/EPA and (n -3)/(n -6) PUFA than those of local trash fish but not for the ARA/EPA ratio. The compositions of egg capsules produced from broodstock fed formulated diet contained significantly more ARA, EPA and DHA compared to broodstock fed the local trash fish. The ARA/EPA and DHA/EPA ratios in egg capsules were significantly higher in the trash fish-fed group compared to those fed the formulated diet. However, (n -3)/ (n -6) PUFA ratios in egg capsules produced from broodstock fed the formulated diet did not differ significantly compared to those from broodstock fed the local trash fish. The relatively low DHA/EPA, ARA/EPA and (n -3)/(n -6) ratios in the egg capsules produced from the formulated diet-fed broodstock B. areolata suggested that this diet is inferior, when compared to the traditional food of trash fish.

“…In particular, much attention has been paid to both survival and growth of experimental batches of hatchery-reared O. edulis larvae and spat (Davis and Calabrese, 1969;Laing and Millican, 1986;Spencer and Gough, 1978;Utting, 1988;Berntsson et al, 1997;Rodstrom and Jonsson, 2000), and to the biochemical composition of larvae fed on different food regimes (Ferreiro et al, 1990;Millican and Helm, 1994).…”

Shellfish aquaculture is a widespread activity in the Italian peninsula. However, only two bivalve species are mainly cultured along the coastline of that country: the Mediterranean mussel Mytilus galloprovincialis and the Manila clam Venerupis philippinarum (Ruditapes philippinarum). By contrast, just a few other mollusc species of commercial interest are scarcely reared at a small-scale level.After analysing the current status of Italian shellfish production, this paper reports and discusses the potential for culturing several different invertebrate species [i.e., the European flat oyster Ostrea edulis, the grooved carpet shell Venerupis decussata (Ruditapes decussatus), the razor clams Ensis minor and Solen marginatus, the cephalopod Octopus vulgaris, and the purple sea urchin Paracentrotus lividus] in this country.In addition, a detailed overview of the progress made in aquacultural techniques for these species in the Mediterranean basin is presented, highlighting the most relevant bottlenecks and the way forward to shift from the experimental to the aquaculture phase. Finally, an outlook of the main economic and environmental benefits arising from these shellfish culture practices is also given.
