Studies on the quality and safety aspect of some commercially important marine fishes of the Bay of Bengal along the Cox’s Bazar coast of Bangladesh

Abstract

Moisture, ash, crude protein and lipid content (%) of <em>Stromateus cinerius</em> was 77.91±1.32, 2.52±0.2, 14.24±1.07, and 2.82±0.16 respectively; <em>Lates calcarifer</em> was 77.99±0.17, 3.63±0.16, 16.79±0.45 and 1.55±0.13 respectively; <em>Trichiurus haumela</em> was 75.22±0.51, 2.76±0.23, 15.19±0.64 and 4.25±0.07 respectively; <em>Harpodon nehereus</em> was 86.39±0.75, 0.75±0.38, 10.11±1.2 and 2.29±0.45 respectively and <em>Hilsa ilisha</em> was 68.05±1.85, 3.19±0.09 and 16.59±0.07 respectively. TVB-N content (mg/100g) of <em>Stromateus cinerius</em>, <em>Lates calcarifer</em>, <em>Trichiurus haumela</em>, <em>Harpodon nehereus</em>, and <em>Hilsa ilisha</em> was 24.58±0.6, 20.63±0.31, 24.68±0.1, 25.53±0.21 and 23.39±0.3 respectively. TMA-N content (mg/100g) of <em>Stromateus cinerius</em>, <em>Lates calcarifer</em>, <em>Trichiurus haumela</em>, <em>Harpodon nehereus</em>, and <em>Hilsa ilisha</em> was determined as 2.116±0.0, 2.11±0.0, 2.62±0.52, 2.7±0.54 and 2.06±0.0 respectively. In case of heavy metal the Cd and Cu concentration of all fishes was within the Maximum Allowable Limit i.e <1 ppm Cd and <10 ppm Cu. However the Cr, Pb concentration in the fishes was above Maximum Allowable Limit i.e >0.05 ppm Cr and >2 ppm Pb except <em>Stromateus cinerius</em> in which Cr was nil and Pb was 1.62 ppm.
