“…While regionally depth and distance to land may be correlated, they are not globally (r = −0.46, p ≥ 0.05, Additional file 1: Table S1) because of the variation in sizes of continental shelves and occurrence of mid-ocean islands. Sea surface temperature (SST), dissolved and saturated oxygen, and surface current may also affect the distribution, growth, reproduction, juvenile survival and mortality of Solen species [14,17,[26][27][28][29]. Razor clams are filter feeders and consume phytoplankton as a food source.…”

Razor clams (Pharidae and Solenidae) are deep-burrowing bivalves that inhabit shallow waters of the tropical, subtropical, and temperate seas. Using 'maximum entropy' , a species distribution modelling software, we predicted the most suitable environments for the entire family and 14 Solen species to indicate their present and future geographic distributions. Distance to land, depth, and sea surface temperature (SST) were the most important environmental variables in training and creating the present and future distribution models both at the family and species level. In the present distribution models at the family level, the most suitable environment was where distance to land was between 0 and 100 km, a depth of 0-150 m, wave height of 5-7 m, a mean chlorophyll-a concentration about 0.7 mg m −3, and mean SST between 12 and 28 °C. Comparison with the future distribution models at the species level, found that most species were predicted to shift their distribution ranges poleward under the future environmental scenarios; i.e. species in the northern hemisphere would shift northward and southern species southward. Models also predicted that half of the species would expand their distribution ranges, 29% of species would not change their distribution, and 21% of species would shrink their distribution ranges under future climate change. Expanding geographic ranges would result in overlap in species ranges and thus greater species richness at regional scales. Model results predict that the mid-latitude peaks of species richness will move further apart, increasing the dip in richness near the equator, due to global climate change.

“…Peaks 1-4 represent the main endogenous FAs of S. cerevisiae, namely C16:0 (1), C16:1n-7 (2), C18:0 (3) and C18:1n-9 (4). The remaining main additional peaks (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17) correspond to the exogenously added FAs and the products of their elongation-C18:2n-6 (7), C20:2n-6 (8), C20:3n-6 (9), C22:3n-6 (10), C22:3n-6 (11), C20:4n-6 (12), C22:4n-6 (13), C18:3n-3 (14), C20:3n-3 (15), C20:5n-3 (16) and C22:5n-3 (17). Other minor peaks are 20:1n-9 (5) and 20:1n-7 (6), the latter two resulting from the elongation of 18:1n-9 and 18:1n-7.…”

“…Previous studies have showed that these PUFAs are crucial to the survival, growth, development and reproduction for molluscs, such as Mytilus galloprovincialis [8], Babylonia areolata [9], Solen marginatus [10], and Ostrea angasi [11], etc. Decades of research on PUFAs of elongation and desaturation activity in bivalves has improved our understanding of the PUFAs synthesis pathway.…”

The elongases of fatty acids (ELO) are essential for long chain polyunsaturated fatty acid (LC-PUFA) biosynthesis, and their activities depend on the substrates. The full length cDNA of Crassostrea angulata ELO (CaELO) was cloned by RACE PCR and its function was confirmed. The CaELO encodes a polypeptide of 309 amino acid residues, which containes a histidine box HXXHH motif conserved in all elongases and shares high similarity to the elongases of Chlamys nobilis and Octopus vulgaris. Phylogenetic analysis showed that the putative elongase was placed in the same group with ELOVL2 and ELOVL5, which have been demonstrated to be critical enzymes participating in the biosynthesis of PUFAs in vertebrates. When expressed in Saccharomyces cerevisiae, CaELO was able to elongate n-3 and n-6 PUFA substrates with chain lengths of C18 and C20, indicating that the CaELO had similar substrate specificities to vertebrate ELOVL5. CaELO had lower activity to elongate monounsaturated fatty acids, but had not activity to saturated fatty acids. Interestingly, the conversion rate of PUFAs depended on the length of carbon chain, the number of double bond, and n-3 / n-6 series in the species.

“…Larval culture duration is very short in S. marginatus (8 days), due to the high levels of stored reserves in eggs (da Costa et al, 2011b), and a larval survival ranging from 28 to 81% (53% on average) was recently achieved by da Costa and MartinezPatiño (2009) in specimens obtained from adults spawned in hatchery by induction. As a consequence of the large size of eggs and the short length of the larval stage, a different pattern in the use of gross biochemical and fatty acid reserves during larval development compared to other razor clams and bivalve species was recently found (da Costa et al, 2011b). A dramatic reduction in survival was obtained by the same authors in 1-month-old spats (8.6%), the bottleneck phase resulting at the post-larvae age corresponding to 1 mm in length (15 to 22 day from settlement).…”

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.
