Abstract

Fish samples of Sardinella albella were collected seasonally from Balochistan coast during (Pre-monsoon, Monsoon, Post-monsoon) season in (January 2012 - December 2012). The maximum mean length (cm) and weight (g) of the fish were (20.1 ± 0.29 cm) and (93.13 ± 1.9g) in Monsoon season and the lowest mean length (18.5 ± 0.58cm) and weight (82 ± 3.60 g) were measured in Pre-monsoon season. Determinations of heavy metals were made by Atomic Absorption Spectrophotometer (AA Analyst). The highest mean concentration of Fe (496.43 ± 41.79µg/g), Mn (9.42 ± 0.81µg/g), Zn (66.22 ± 7.06µg/g), Pb (2.42 ± 0.21 µg/g), and Cu (14.69 ± 2.30µg/g) were recorded in liver. The lowest mean concentration of Fe (3.82 ± 0.91µg/g), Mn (1.41 ± 0.62µg/g), Zn (1.88 ± 0.25µg/g), Cd (0.64 ± 0.16 µg/g), Pb (0.35 ± 0.06 µg/g), and Cu (1.69 ± 0.14µg/g) were recorded in fish muscles. Metals concentration didn’t vary seasonally and following trends of metal concentrations were observed in various organs of S. albella. Muscles: Fe > Zn > Mn > Cd > Pb Liver: Fe > > Zn > Cu > Mn > Pb > Cd Gills: Fe > Zn > Mn > Cu > Cd > Pb
