Comparison of Iron concentration in the muscle, liver and gill of farmed common carp (Cyprinus carpio), in the warm water fish ponds of Khuzestan Province of I.R. Iran

This study was conducted in order to determine the Iron levels in muscle, liver and gill tissues of Cyprinus carpio at the farmed ponds in Karoon river of three area, north (Shushtar), center (Ahvaz) and South (Khoramshahr) from Khuzestan Province of I.R. Iran in 2010. Fifteen fish were collected from each area. Iron was extracted and its concentration was measured using Atomic Absorption Spectrophotometer, Perkin Elmer. Data were statistically analyzed with SPSS14 at 0.05 confidence level. The order of Fe concentration in organs of Cyprinus carpio was gill> liver> muscle. The average of Fe levels in muscle, liver and gill were 0.82± 0.07, 6.18± 0.61 and 6.66± 0.45 mg/ Kg dw, respectively. The highest and lowest concentration of Fe in fish muscle were observed in Khoramshahr and Shushtar area, which were 0.98 and 0.54 mg/ Kg dw, respectively. According to the results of this study, accumulation of Fe in muscle of Cyprinus carpio was higher than FDA standards (0.5 ppm).
