| Summary: | The Ayeyarwady river is the life-blood of Myanmar people and fresh water aquatic organisms. So, in this research work, one of the well-known commercial fishes, Nga-but (Wallago attu) was collected for chemical analysis. The sample was collected from Mayangyan Jetty, Ayeyarwady river, Mandalay. The amount of protein present in the sample was measured by micro Kjeldahl’s method. The protein content of flesh sample was found to be 20.06% - 20.50%. Ash content of sample was determined by oven drying method. The ash content of flesh, bone, internal organs were found to be 0.86%, 3.49%, 1.25% and 1.12% respectively. Water content of sample was determined by Dean and Stark dislillation method. The water content of flesh sample was found to be 54.77%-55.55%. Mineral compositions (K, P, Ca, Fe, As, Cd, Hg, Pb, etc) in sample were analyzed by using Spectro XEPOS EDXRF spectrometa, Germany. The potassium, phosphorus, Calcium, Iron, Arsenic, Mercury and Lead contents of flesh sample were found to be 23.27%,13.82%, 1.11%, 0.88%, 0.00004%, not detected, 0.00026% and 0.00011% respectively. |
