“…Substitutions of microalgae with processed diets, such as yeast and plant-based flours, have been shown to be effective for the cultivation of Tapes philippinarum (Caers et al 1999), Ruditapes decussatus (Albentosa et al 1999), and Mercenaria mercenaria (Epifanio 1979). Albentosa et al (1999) in their study with T. philippinarum spat have successfully replaced up to 50% of the daily food ration with wheat germ flour.…”

A set of feeding trials was carried out for different microalgal species and processed diets for the culture of the New Zealand pipi, Paphies australis. Five microalgal species (Isochrysis galbana clone T-ISO, Pavlova lutheri, Tetraselmis suecica, Chaetoceros muelleri, and Thalassiosira pseudonana clone 3H) and three formulated diets (baker's yeast, wheat flour, and corn flour) were fed to spat, juvenile, and adult pipi for 21 days. Unfed pipi were used in the control group. The spat and juvenile pipi showed the major shell increase with I. galbana, while the greatest wet weight increase was obtained with P. lutheri. The shells of adult pipi grew better with corn flour and P. lutheri-fed group obtained the greatest wet weight. Results of proximate analysis in adult pipi revealed that proteins and lipids were accumulated in the tissue for all fed groups, while carbohydrate levels depleted in all treatments including the control group. It is suggested that the gonads have developed during the experiment.

“…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

“…Lipids were first successfully supplied to bivalves using gelatin-acacia microcapsules (GAM) (13)(14)(15)(16) and lipid microspheres (17)(18)(19). Emulsions were subsequently demonstrated to be an alternative way to deliver EFA (20)(21)(22)(23) and sterols (24). Liposomes also have been used to deliver essential lipids and water-soluble compounds to oysters (25)(26)(27)(28).…”

The present study tested two techniques for dietary supplementation of Crassostrea gigas spat with PUFA, such as arachidonic acid (AA). The first technique consisted of a preliminary enrichment and growth of an algal concentrate (T-ISO, Isochrysis sp.) with AA dissolved in an ethanol solution, the whole culture then being fed to the spat. This enrichment increased the AA weight percentage in T-ISO neutral and polar lipids from 0.6 to 22.4% and from 0.4 to 6.8%, respectively. The second delivery technique was direct addition separately of free AA dissolved in ethanol solution and algal concentrate (T-ISO + AA) to the spat-rearing tank. To test the efficiency of these delivery techniques, oyster spat were supplemented with AA-enriched T-ISO, T-ISO + AA, and T-ISO alone. The possible biological impacts of these dietary treatments were assessed by measuring growth, condition index, and TAG content of oyster spat. Dry weight and condition index of spat fed AA-enriched T-ISO decreased by 24 and 49%, respectively, after 26 d of feeding; basically, TAG content declined 88% after 34 d of conditioning. When AA was added directly to seawater, spat growth and condition index were comparable with those of oysters fed T-ISO alone. AA incorporation in oyster tissues was assessed by analysis of the FA compositions in both neutral and polar lipid fractions. After 34 d, AA content in neutral lipids reached 7 and 11.7% in the spat fed, respectively, AA-enriched T-ISO and T-ISO + AA, as compared with 1.1% in spat fed only T-ISO. AA incorporation was greater in polar lipids than in neutral lipids, reaching 7.8 and 12.5% in spat fed AA-enriched T-ISO and T-ISO + AA, respectively. A direct addition of PUFA along with the food supply represents an effective and promising means to supplement PUFA to oyster spat.
