Abstract
This study was conducted to determine the nutritional value of hilsa fish from the six selected regions in Bangladesh. The moisture, protein, fat, carbohydrate and energy value were found 66.94 ± 7.34 to 72.04 ± 5.77%, 18.95 ± 3.97 to 20.56 ± 4.57%, 4.97 ± 0.89 to 8.21 ± 1.87%, and 3.08 ± 0.68 to 4.84 ± 1.22%, 0.35 ± 0.09 to 0.72 ± 0.05% and 128.38 ± 11.43 to 161.68 ± 13.21 kcal/100 g respectively. The pH, TVB-N and salt value were found 6.52 ± 0.07 to 6.84 ± 0.10, 2.01 ± 0.71 to 3.50 ± 0.33 mg/100 g and 2.05 ± 0.03 to 6.48 ± 0.07% respectively. The vitamin A and vitamin C value were found 33.50 ± 14.28 to 95.54 ± 11.69 μg/100 g and 11.20 ± 0.47 to 14.28 ± 1.93 μg/100 g respectively. The calcium (Ca), iron (Fe), phosphorus (P), magnesium (Mg), manganese (Mn), copper (Cu) and zinc (Zn) were found 144.21 ± 17.43 to 372.67 ± 17.44 mg/100 g, 9.04 ± 5.14 to 13.07 ± 5.17 mg/100 g, 118.17 ± 13.56 to 204.06 ± 5.89 mg/100 g, 34.18 ± 3.72 to 45.07 ± 9.22 mg/100 g, 8.54 ± 1.79 to 12.68 ± 4.3 mg/100 g, 0.95 ± 0.13 to 1.54 ± 0.29 mg/100 g and 0.94 ± 0.22 to 1.23 ± 0.19 mg/100 g respectively. These values are useful references for consumers in order to choose fish and shellfish based on their nutritional contents. These results also suggest that the proximate composition of hilsa fish greatly varies due to physiological reasons and changes in environmental conditions, i.e., spawning, migration, and starvation or heavy feeding.

Summary
The River Shad, popularly known as hilsa is in great demand globally, in the oriental world and enjoys high consumer preference. In Bangladesh, hilsa fish is mainly caught in the Padma (lower Ganges), Meghna (lower Brahmaputra), and Jamuna rivers. Hilsa fish contributes a total of 346512 MT (Inland 114475 MT and Marine 232037 MT) in 2011-12 [1]. Fish meat is basically composed of water (66-81%), protein (16-21%), carbohydrates (
