Association of Official Analytical Chemists, Gaithersburg, MD, USA.Ī.Watters C, M. The present study gives the basis for improving the knowledge and promoting inland fish’ market and traceability along the supply chain.ĪOAC, 2000. Concerning molecular analysis, a 655 bp fragment of cytochrome C oxidase subunit I (COI) gene was successfully used for the identification at the species level using both BOLD and BLAST public databases. The fraction of polyunsaturated fatty acids (PUFA) revealed a higher DHA content (C22: 6 n3) in Anguilla anguilla than the other species (>12 %) while Chelon ramada presented both higher EPA content (C 20: 5 n3) and total fraction of omega 3 PUFAs. Oleic acid (C18: 1 n9 cis) was particularly high in Cyprinus carpio (55.46%).
As regards the fatty acids profile, the most abundant were MUFAs with the highest value in Anguilla anguilla (45.97%). Moisture, protein, fat, carbohydrates, ash, and sodium content were measured. All the samples were subjected to nutritional and DNA barcoding analysis. In this study, six different fish species were caught in the Fondi lake (Lazio, central Italy): Anguilla anguilla, Tinca tinca, Carassius gibelio, Cyprinus carpio, Micropterus salmoides, Chelon ramada.
Therefore, the marketing of the lake’s fresh and processed fish is limited to the local market and consumers are currently uninformed and mistrustful about these species.
Inland fish are usually considered having unmarked taste and are less appreciated by consumers thus, they have low commercial value. The increasing world market demand for seafood requires an expansion of product categories available to consumers.
