With priority given to various-sized samples of market-available Hilsa (Tenualosa ilisha), human health consequences of trace metals along with total essential acids, including the fatty acid (FA) and amino acid (AA) profile were measured and compared to different size groups (G I, G II, and G III) using chemometric approaches. Essential amino acids were lower than nonessential amino acids. The G III contained the highest (97.55%) saturated and unsaturated fatty acids. The highest concentrated metal was found in G1 among the groups and the order of metal (mg/kg) was Zn (205.01) > Mn (37.37) > Fe (69.39) > Cu (1.47) > Cr (1.31) > Ni (0.42) > Pb (0.017) > Cd (0.005). Even though the adult group showed no health hazards for Hilsa consumption, non-carcinogenic risks have been identified for G1 fish consumption by children. Continued monitoring is recommended to overcome the health consequences caused by fish consumption.
