“…For O. edulis broodstock fed diets rich in PUFAs, a transfer of these fatty acids to their larvae was reported by Frolov and Pankov (1992). Lastly, many studies have documented relations between the fatty acid profile of the diet and that of the gonad or larvae contents (Caers et al, 2000;Flores-Vergara et al, 2004;Knauer and Southgate, 1999).…”

“…In contrast, the influence of the relative food value of different phytoplankton species (nutritional quality) on mollusc gonadic development has been very little explored, especially in O. edulis. The pioneer works of Frolov and Pankov (1992) and Millican and Helm (1994) provided relevant information in this field but only a few studies (Berntsson et al, 1997) have been carried out since. Indeed the appearance in France in the 1970-1980s of epizooties of Marteilia refringens (Comps, 1970) and Bonamia ostreae (Comps et al, 1980) and their progressive extension throughout Europe (see review in Laing et al, 2005) led to the collapse of O. edulis culture and research then focused more effort on recently introduced species (e.g., C. gigas: Helm and Millican, 1977;Robert et al, 1982;and R. philippinarum: Helm, 1990;Utting and Spencer, 1991).…”

The selection of an ideal diet for Ostrea edulis (L.) broodstock conditioning (part B)

International audienceFour microalgae species (Rhodomonas salina, Thalassiosira weissflogii, Thalassiosira pseudonana and Pavlova lutheri) were evaluated to estimate their potential as food for Ostrea edulis (L.) reproductive conditioning. Best ingestion and absorption were observed with R. salina (3.44 and 1.59 mg g− 1 h− 1, respectively), followed by T. pseudonana (2.75 and 0.98 mg g− 1 h− 1) and P. lutheri (2.40 and 0.91 mg g− 1 h− 1). Oysters fed T. weissflogii exhibited the lowest ingestion and absorption values (1.40 and 0.68 mg g− 1 h− 1). Proximate composition (proteins and carbohydrates) and lipid content (fatty acids and sterols) analysed in four main tissues (gonad, digestive gland, muscle and gills) also differed significantly with diet. Protein ranged from 355 mg g− 1 in the gonad of oysters fed P. lutheri to 837 mg g− 1 in gills of oysters fed T. weissflogii; whereas carbohydrates ranged from 17.5 mg g− 1 in gills of oysters fed P. lutheri to 271 mg g− 1 in gonads of oysters fed R. salina. An overall poor enrichment in total PUFAs across all diets masked some of their potential impact on nutrition. In gonad, however, the major polyunsaturated fatty acids (polar lipid fraction) were EPA (≈ 19% for oysters fed T. weissflogii and 14% for those fed P. lutheri) and DHA (17% for oysters fed P. lutheri and 15% for those fed R. salina). Sterol contents showed a clear transfer from food to oyster tissues except with P. lutheri, from which neither methylpavlovol nor ethylpavlovol (characteristic of Pavlophyceae) were detected in oyster tissues. Histological analysis showed that gametogenesis was active in oysters fed R. salina and T. weissflogii, whereas only low gonadic development occurred in unfed oysters or those fed P. lutheri. R. salina is accordingly highly recommended for O. edulis broodstock conditioning whereas P. lutheri should be excluded

“…There is little published work related to optimal algal size and algal densities in O. edulis broodstock conditioning. In contrast, more information is available on the nutritional requirements at different stages of development: broodstock (Frolov & Pankov 1992), larvae (Ferreiro, Pérez‐camacho, Labarta, Beiras, Planas & Fernandez‐reiriz 1990) and juvenile (Enright, Newkirk, Craigie & Castell 1986). Nevertheless, the relationship between broodstock feeding and larval development remains poorly known.…”

To select the best microalgae for Ostrea edulis conditioning, four single species diets were fed to batches of broodstock, which were then compared using physiological and biochemical approaches. Ingestion and absorption were first studied, showing that Chaetoceros gracilis and Skeletonema marinoï were efficiently ingested (4.9–5.3 mg g−1 h−1) and absorbed (1.9–2.5 mg g−1 h−1) while Tetraselmis suecica led to the lowest physiological responses (0.36 and 0.12 mg g−1 h−1 respectively). When O. edulis were fed any microalgae except T‐ISO with only 79 mg g−1, gonads accumulated carbohydrates from 116 to 141 mg g−1 and the extent of accumulation depended on the species supplied in the order T. suecica

“…Among all C 24 unsaturated fatty acids found in female gonad lipids, 9,17-24:2, 9,15,18-24:3, 5,9,15,18-24:4, 5,9,15,18,21-24:5, 24:4n-6, and 24:5n-3 were not detected in male gonad lipids of this species. Although trace amounts of C 24 polyunsaturated fatty acids (PUFAs) of both n-6 and n-3 series (< 0:1%) have been found in the oyster Ostrea edulis 11) and eight marine gastropod species from the littoral zone of the Red and Mediterranean Seas, 12) a comparative biochemical study of C 24 PUFA composition in the gonads of marine gastropod species has been done only for the oyster gonad of O. edulis.…”

The occurrence of positional isomers of minor C 24 unsaturated fatty acids in female gonad lipids of the limpet Cellana grata was clarified by gas chromatography-mass spectrometry of the combination of their 4,4-dimethyloxazoline and picolinyl ester derivatives. In this study, in addition to 5,9-24:2, 9,15-24:2, 5,9,15-24:3, and 5,9,17-24:3, previously identified, 24:4n-6, 24:5n-3, and four novel nonmethylene-interrupted fatty acids, 9, 17-24:2, 9,15,18-24:3, 5,9,15,18-24:4, and 5,9,15,18,21-24:5, were newly recognized. All C 24 unsaturated fatty acids detected were present only in triacylglycerols.
