“…The fatty acid composition of P. lividus gonads in the present study is in general agreement with the literature (Arafa, Chouaibi, Sadok, & El Abed, ; Martinez‐Pita, Garcia, & Pita, ; Serrazanetti, Pagnucco, Conte, & Cattani, ; Siliani et al., ). Stearic acid, palmitic acid, EPA and ARA are the most abundant fatty acids in P. lividus gonads.…”

“…Variations in the lipid composition of sea urchin gonads has been found, related to both endogenous and exogenous factors such as water temperature, season, growing stage and sampling area (Siliani et al., ; Zárate, Díaz De Vivar, Avaro, Epherra, & Sewell, ). It has also been suggested that dietary lipids play a key role in establishing the fatty acid profile of sea urchin gonads (Carboni, Hughes, Atack, Tocher, & Migaud, ; Marsh et al., ; Martinez‐Pita et al., ). However, a recent study by Kabeya et al.…”

Gonad quality of sea urchin Paracentrotus lividus cultured in an offshore pilot-scale trial on the south-east Italian coast

A pilot project aimed at testing roe enhancement strategies based on offshore Paracentrotus lividus cultures was conducted off the south‐east coast of Italy (Apulia Region). Adult sea urchins were reared in sea cages located 700 m offshore at a depth of 12 m for 3 months. The animals were fed once a week on two formulated diets, prepared mixing nutrients with agar 20 g/Kg and differing only in terms of the protein source: anchovy flour (Diet A) or krill flour (Diet K). At the end of the rearing trial, the gonad somatic index of sea urchins fed on formulated diets significantly exceeded that of wild sea urchins. Total FAA content in the gonads of wild sea urchins and Diet A‐fed sea urchins was similar, whereas in Diet K‐fed sea urchins it was significantly higher. In terms of fatty acids, the gonads contained SFAs, MUFAs and PUFAs. In visual and sensory assessment of gonads by panel test and electronic nose, the gonads of reared sea urchins were rated as being of better size, while no differences were recorded for coloration, taste and odour. This study shows that under these experimental conditions, commercial‐grade Paracentrotus lividus roe enhancement can be achieved after 3 months in sea cages.

“…Thus, an understanding of the biochemical requirements for growth and development of nutritive phagocytes is necessary to optimize the feeds for sea urchins in aquaculture (Marsh et al, ). Previous studies have evaluated the variation of lipid levels in sea urchins over time, but the results were contradictory (Martinez‐Pita et al, ). However, large amounts of spermatozoa and oocytes accumulate in the gonads as they mature, which confers a peculiar lipid composition to the gonadal tissue (Siliani et al, ).…”

“…To create the appropriate diet for these purposes, it is necessary to understand the nutritional profile of sea urchins throughout their gametogenic development. In fact, it has been referred that dietary lipids have a key role in the fatty acid profile of roe (Carboni et al, ; Martinez‐Pita, Garcia, & Pita, ; Siliani et al, ) and consequently, in their organoleptic attributes. Accordingly, three diets were tested, with macroalgae and vegetables, to compare the somatic growth of P. lividus sea urchins, but also the growth and nutritional quality of their gonads.…”

Effect of three diets on the gametogenic development and fatty acid profile of Paracentrotus lividus (Lamarck, 1816) gonads

In this study, the effects of three diets were investigated to enhance Paracentrotus lividus production for commercial purposes. P. lividus were fed ad libitum for 80 days with: diet A—fresh Codium tomentosum Stackhouse, 1797; diet B—formulated using a jellified mix of macroalgae and vegetables, including C. tomentosum (20%), Coralina sp. Linnaeus, 1758 (17%), cabbage Brassica oleracea var. capitata Linnaeus, 1753 (30%), carrot Daucus carota Linnaeus, 1753 (30%) and agar (3%) as a gelling agent. Diet C consisted of maize Zea mays Linnaeus, 1753 (56%) and New Zealand spinach Tetragonia tetragonoides (Pallas, 1781) Kuntze, 1891 (44%). Their effects on the gonadal and somatic growths, gonadosomatic index (GI) and gametogenesis were evaluated, as well as on the total lipid content and fatty acid composition of sea urchin's gonads. Diet A provided high values of eicosapentaenoic acid (EPA). Gonads of sea urchins fed with diet A were found mostly in growth and maturation stages of gametogenesis and showed the lowest lipid content. Sea urchins fed with diet B presented their gonads in the reabsorption stage and had the highest values of omega‐3 polyunsaturated fatty acids (PUFAs). Sea urchins fed with diet C were in the early stages of gametogenesis and had the highest values of lipid content, plus omega‐6 PUFAs. Once as an ingredient in a balanced mix with vegetables, C. tomentosum can be a key factor to the development of new promising high‐quality and low‐cost feed for P. lividus roe enhancement.

“…It is generally recognized that FA compositions of sea urchin gonads reflect dietary inputs although reproductive status could alter relative FA abundance in P. lividus (Hughes et al, 2005, Martinez-Pita et al, 2010. However, a complete description of the FA profile of each gametogenic stage is not currently available.…”

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.
