Proximate, lipid, and fatty acid composition of farmed and wild meagre (Argyrosomus regius) muscle, head, skin, and liver, were comparatively studied. Distinct differences were evident in the lipid and fatty acid composition among different tissues of farmed and wild meagre. Total lipid content of the farmed fish parts was significantly higher than that of the wild fish. Neutral lipids, mainly triglycerides, predominated in muscle, head, and skin for both fish. The fact that muscle fat was found significantly lower in triglycerides (TG) concentration than head and skin indicates that muscle consumption after head and skin removal may contribute to a healthy diet. Wild fish muscle, head, and skin fat was found to have significant contribution to the phosphatidylcholine daily intake in the human diet. A. regius liver was also found to be an excellent source of glycerophospholipids. Fatty acid patterns of muscle, head and skin of farmed fish were found to be affected by the feed. MUFA/saturated fatty acid (SFA), PUFA/SFA, and DHA/eicosapentaenoic acid (EPA) ratios were found significantly higher in muscle, head, and skin TL of wild fish compared to the farmed one. Farmed fish muscle could provide similar amount of EPA + DHA and significantly higher amount of ω-3 PUFA compared to wild fish muscle.



Practical applications: Argyrosomus regius is considered a promising fish species for aquaculture due to its tasty meat and great market acceptance in the Mediterranean countries. Hence it is important to determine its lipid and fatty acid content of both farmed and wild fish edible parts (muscle, head, and skin) for nutritional purposes. Remaining parts (such as liver) could still be interesting to analyze for possible use in other food or nutraceutical applications. Here we compare the distribution pattern of lipids and fatty acids of muscles, heads, skin, and liver in wild and farmed A. regius, fed a commercial diet. Furthermore, the present study is a novel comparison between cultured and wild fish species A. regius in terms of their proximate and fatty acid composition.

abstract = {An efficient separation and quantification of the individual neutral and polar lipid classes and their constituent fatty acids was achieved by the combination of two different detection techniques: Iatroscan TLC-FID and GC-FID. The solvent composition and ratio of development system, the sample size, the fidelity, and precision were tested in order to estimate the effectiveness of separation of individual neutral and polar lipid classes and the quantitative reproducibility of the Iatroscan TLC-FID technique. GC-FID method, with a high-quality capillary column, allowed sensitive and reproducible fatty acid qualitative and quantitative analyses, separation of fatty acid structural isomers (e.g., n-C16:0, iso-C16:0 and anteiso-C16:0), positional isomers (e.g., C18:1ω-9 and C18:1ω-7), geometrical isomers (cis-trans), and homologues (e.g., C16:0, C17:0, C18:0, etc.) in standards and complex lipid samples. Seventeen (17) lipid classes and fifty-two (52) saturated (SFA), monounsaturated (MUFA), and polyunsaturated (PUFA) fatty acids were identified and quantified, respectively, in samples of standard lipid and fatty acid mixtures, simulating the composition of natural lipids and their fatty acid methyl esters in common foods. The wide number of applications establishes this combination of Iatroscan TLC-FID and GC-FID methods as a powerful tool for lipid class and fatty acid analysis of any fat origin.},
