Author(s): Ghazala Jabeen, Muhammad Javed, Abdul Rauf
Abstract: Heavy metals were analyzed in the samples of herbivorous fishes, Catla catla, Labeo rohita and Cirrhina mrigala collected from the three public fishing sites, Shahdara bridge, Baloki headworks and Sidhnai barrage of the river Ravi during the sampling year, 2009-2010. All the three fish species exhibited significantly different abilities to accumulate metals in their body organs with the order: Al> As> Ba. The concentrations of heavy metals showed significant amassing of aluminium and arsenic in all the body organs of herbivore fishes while barium accumulations were significantly least in fish body at all the sampling stations. The three species of fish had the mean metallic toxicity levels followed the order: Cirrhina mrigala> Labeo rohita> Catla catla. The fish at Shahdara bridge were more contaminated with Al, followed by As and Ba with statistically significant differences.
