“…The latter was determined in both molluscs but in a definitely higher percentage in mussels. This is in accord with previous findings from other research studies . As above mentioned, from the observation of literature data the clam species Venerupis aurea appears to be underinvestigated.…”

“…Many more papers explored fatty acids in mussels of the common species M. galloprovincialis . Previous papers have dealt with changes in fatty acid profiles depending upon season, processing, availability of food, environmental conditions, animals’ tissues . In this study, a method based on the use of comprehensive gas chromatography (GC × GC) was developed for the achievement of bidimensional fingerprints of fatty acids extracted from edible fish and shellfish.…”

Comprehensive two-dimensional gas chromatography-mass spectrometry was exploited for the obtainment of fatty acid fingerprints in fish and molluscs from South Italy. Scope of the lipidomic investigation was to highlight differences in the fatty acid profiles of samples from aquaculture and from the wild. The fish species under investigation were Sparus aurata and Dicentrarchus labrax, typically cultivated in Italy and commonly found in the fish market. Another aim was to find a correlation between the diet fed to fish and the expression of specific fatty acids in muscle composition. Beyond fish, two species of bivalves were analyzed to assess their lipidomic composition: Mytilus galloprovincialis (mussels) and Venerupis aurea var. laeta (clams). Both species originated from two salt lakes in South Italy. GC Â GC-MS analysis showed that omega-3 fatty acids were naturally more concentrated in wild fish, whereas their presence in cultivated fish was lower and in favor of omega-6 and oleic acids, as an evident consequence of food supplementation. Bivalves reported a consistent amount of PUFA, although presenting some differences in the quality of fatty acids. As an additional parameter of investigation, the content of mercury was determined in all the samples by means of a Direct Mercury Analyzer, based on Atomic Absorption Spectroscopy. Wild fish reported a level of mercury that was ten times higher than in aquafarmed fish, and the maximum amount tolerated by the EC regulation. On the contrary, the level of mercury in molluscs was in general very low, particularly when compared with samples from other Italian sites of collection.Practical applications: One of the possible applications of the GC Â GC methodology here presented could be the detection of a common food fraud. In the Mediterranean Sea, gilthead sea bream and sea bass are today rarely found in sea open waters. Basically, fish sold in the market comes from cultivation. Due to the fact that wild fish is more appreciated by the consumer, quite often fish sellers are encouraged to lie about the real origin of fish. The bidimensional plots shown in this study represent an extraordinary tool for differentiating the two types of fish. Also, this study provides substantial support to aquafarmers, who can draw useful advice on how to tune optimal diets to be fed to fish. In fact, it was demonstrated that fish feed highly affects fatty acid composition.

“…However, EPA and DHA proportions signifi cantly (p<0.05) differed among the bivalve species. M. galloprovincialis showed the highest EPA level with 11.74% of total FAs, while the highest DHA was found in M. varia and L. tuberculata (10.88-14.41% of total FAs), which is in line with literature data [Bongiorno et al, 2015;Dernekbasi et al, 2015;Prato et al, 2010;Radić et al, 2014;Telahigue et al, 2010]. In turn, Azpeitia et al [2016] in their study with mussels (M. galloprovincialis) cultured in the Bay of Biscay (northern Spain) found lower levels of EPA (8.77%-8.82% of total FAs) and higher levels of DHA (18.24%-22.49%) than those determined in our study.…”

“…The major MUFAs were palmitoleic (C16:1) and oleic (C18:1 n-9) acids, which is in agreement with literature data [Bongiorno et al, 2015;Fuentes et al, 2009]. However, the relative contents of these fatty acids differed widely among all species.…”

for the synthesis of resolvins, which are believed to play a key role in terminating inflammatory processes [Kohli & Levy, 2009]; moreover, they have benefi cial effects on other diseases, namely skin disease, asthma, arthritis, nephritis, lupus erythematous, multiple sclerosis, and certain types of cancers [Harris, 2010; Massaro et al., 2010]. PUFAs are infl uenced by taxonomic relations and environmental conditions and depend on species, nutrient habits, food availability and physiological conditions, so they differ for molluscs species that come from different geographical areas [Orban et al., 2007]. Minerals such as sodium, potassium, magnesium, calcium, iron, zinc and copper, are essential substances for organisms and for their vital functions and growth. In fact, minerals are important components of hormones and enzymes activated in human nutrition [Khan, 1992], and are involved in physiological processes in the body, the most important of which are pH maintenance, osmotic pressure, nerve conductance, muscle contraction and energy production. Zinc, for example, has different important biochemical functions, in particular as cofactor to more than 300 enzymes involved in DNA and RNA metabolism and stabilization of cell membranes [Beyersmann, 2002; Rink & Gabriel, 2000]. Unsuited dietary intakes of the minerals Ca, Mg, Na and K, either insuffi cient or excessive, can cause serious health issues such as cardiovascular disease, osteoporosis, and hypertension. In general, the seafoods are excellent sources of Ca, K, Na, Fe, Zn, Cu and in particular, oysters are good sources of Fe, Zn, and Cu.

“…Bivalve molluscs, besides their fundamental role within the marine ecosystem (Newell, 2004), are of substantial economic value in the aquaculture industry. Indeed marine molluscs, including the Mediterranean mussel Mytilus galloprovincialis (Lamarck 1819), a very popular shellfish with a wide geographical distribution worldwide (Branch and Stephani, 2004), are commonly included in human diet because of their exceptional nutritional value (Bongiorno et al, 2015;Cappello et al, 2018). Mussels are routinely used as good bioindicators in ecotoxicological studies (Cappello et al, 2017a(Cappello et al, , 2017bGiannetto et al, 2015Giannetto et al, , 2017Maisano et al, 2017) and, due to their filter-feeding habit, are also known to accumulate large numbers of bacteria from the surrounding waters.…”
