PROXIMATE AND MINERAL COMPOSITION OF FOUR TENGRA (MYSTUS SP.) FISHES OF BANGLADESH

Body flesh of the four fish species (Mystus) namely Mystus gulio, bleekeri, cavasius, and vittatus were collected proximate composition mineral contents (Na, K, Ca, Mg, P, Fe, Zn Cu) analyzed. The highest amount protein (22.2±0.94%) lipid (5.25±0.64%) found in M. gulio. maximum moisture (79.31±1.86%) ash content (1.45±0.14%) observed cavasius where gulio showed lowest (71.5±0.95 %) (1.03±0.06%).The concentration range Na, P 128±5.09 mg to 288± 2.94 mg, 67.2±0.8 86±2.16 254.5±2.43 316.8±3.98 43.0±1.31 47.4±1.31 122.5±1.89 220±1.8 per 100 g respectively. Na (86±2.16 mg) (220±1.8 mg). Among fish, had Ca (288±2.94 while both K (316.8±3.98 Mg (47.40±1.31 Micro different more or less similar except which a higher Fe (5.47±0.56 as contained no Cu.
