Estimation of Mineral Ca, Mg, Fe, Cu and Zn Content in Common Fish of Bangladesh

Abstract

The present article reports the content of mineral content (Ca, Mg, Fe, Cu and Zn), and moistute in some indigenous fishes.
Mineral contents were determined by Atomic Absorption Spectrophotometer (AA-6800) after appropriate digestion of the
fish samples, and moisture was determined by AOAC method. Calcium and magnesium content were found to be highest
in Mola (Amblypharyngodon mola) followed by Ketchki (Coria soborna), the iron, copper and zinc amounts were higher
in Ketchki (Coria soborna) than the Mola (Amblypharyngodon mola) fish. The other fishes contained little amounts of
these minerals compared to the Mola and ketchki. Moisture content was in a range of 71.90 g % in Pangas to 80.73 g % in
Ketchki. The Mola and ketchki are very rich in mineral contents (Ca, Mg, Fe, Cu and Zn), regular intake of which would
certainly fill up the mineral deficiency of the people.
