| Abstract: | The nutritive composition in muscle of Gymnocypris przewalskii was analyzed. It showed that the muscle consisted of 79.37 % water, 19.28 % crude protein, 1.73% fat and 1.25 % ash. The content of mercury was 0. 123 4 mg/kg, arsenic was 0. 130 6 mg/kg, copper was 0. 255 mg/ kg, zinc WaS 2. 255 mg/kg, lead was 3.485 mg/kg and cadmium was 0,0. 09 mg/kg. Zinc content surpassed the national food standard near 7 times. |
