“…These results suggest that the flesh of all examined species (except for Nile Tilapia) is of high nutritional quality and affords great benefits to human health [ 80 ]. According to De Sousa et al [ 81 ], Nile tilapia from continental aquaculture in Paraiba State (Brazil) can be recommended for human consumption due to low AI and TI indices and hypocholesterolemic/hypercholesterolemic fatty acids ratio (H/H). Similarly, all of the farmed fish species except turbot ( Scophthalmus maximus L.) had the recommended levels of the atherogenicity index, thrombogenicity index and hypocholesterolemic to hypercholesterolemic fatty acids ratio, whereas the highest flesh-lipid quality value was observed in the dentex ( Dentex dentex L.) [ 82 ].…”

The aim of this study was to determine the mercury content and fatty acids profile in roach (Rutilus rutilus L.) and European perch (Perca fluviatilis L.) from Lake Łańskie (Poland). Mercury content was higher in the muscles than other organs in both species (p < 0.05). Mercury accumulates along the food chain of the lake’s ecosystem. The value of the bioconcentration factor (BCF) indicated that Hg had accumulated in the highest amounts in muscles and in the other organs as follows: muscles > liver > gills > gonads. The metal pollution index (MPI) and target hazard quotient (THQ) were below 1, which means that these fish are safe for consumers. The values of HIS, GSI and FCF indicators show that both species of fish can be good indicators of water quality and food contamination. There were few differences between fatty acid content in the muscles of perch and roach. Contents of fatty acids having an undesirable dietary effect in humans (OFA—hypercholesterolemic fatty acids) were lower compared to hypocholesterolemic fatty acids (DFA, i.e., the desirable ones). In addition, the lipid quality indices AI and TI in the muscles of fish were at 0.40 and 0.22 (perch) and at 0.35 and 0.22 (roach), respectively. On this basis, it can be concluded that the flesh of the fish studied is beneficial from the health point of view.
