Bioaccumulation of two macro-elements (Sodium and Potassium) in relation to body size and condition factor of Notopterus chitala from River Indus, Ghazi Ghat, Pakistan

Notopterus chitala is a member of the primitive teleost lineage and considered as commercially important food fish. To study concentration sodium potassium influence fish size condition factor on bioaccumulation these macro-elements, total 16 specimens N. were collected from River Indus. Mean (±SD) body weight, length was found 250.32±113.93 g, 32.93 ± 4.85 cm 0.647± 0.094. Fish samples oven dried, grinded, ashed digested into 1M HNO3 to make sample solution. Flame atomic absorption measurements analyzed detect with spectrophotometer. 255.51± 32.45 µgg-1 range values 206.28-298.70 µgg-1, while observed 1327.15 234.71 815.08-1694.87 in wet weight wild captured chitala. Body represented insignificant correlations concentrations chitala, indicating no dependence essential minerals this species.
