Abstract

The Blue Revolution aims to provide a sustainable food source for disadvantaged populations, focusing on fish as a rich source of fat and high-quality protein. To improve fish consumption recommendations, it is essential to consider local consumption patterns, fish contamination levels, nutrient content, and the nutritional status of the target population. This requires conducting risk-benefit analyses at regional, national, or subnational levels. This study examined several biological and physiological parameters of the common bony fish species captured by trawling nets, specifically: Diplodus sargus, Xyrichtys novacula, Trachurus trachurus, Saurida lessepsianus, Fistularia commersonii, Pagellus erythrinus, Pagellus bellottii, Mullus surmuletus, Boops boops, and Scomber japonicus. Key parameters investigated included total weight, total length, age determination, and food and feeding habits. The results revealed significant differences (P< 0.05) in the accumulation of minerals (Na, Ca, Mg, and Fe) in the white muscles among the examined species. Mean values for these minerals ranged from 160.8 to 289.6μg/ g wet weight for Na; 334.8 to 574.3μg/ g for Ca; 290.9 to 489.0μg/ g for Mg; and 3.3 to 35.1μg/ g for Fe. The accumulation of essential metal selenium (Se) ranged from 0.7 to 4.3μg/ g wet weight, while levels of toxic metals (Cd and Pb) were below detectable limits, except for Pb in D. sargus, which was measured at 0.21 ± 0.01μg/ g wet weight. Additionally, total protein, total cholesterol, low-density lipoprotein (LDL), and triglycerides ranged from 15.5 to 21.9mg/ dl; 9.8 to 21.1mg/ dl; 0.9 to 9.0mg/ dl; and 11.6 to 118.2mg/ dl, respectively, based on wet weight tissue. The status of prooxidation and antioxidant levels was also investigated. These examined species are rich sources of lipids, protein, and trace minerals that are vital for human health. Fish from this study location do not pose a health risk to humans when consumed.
