A study was conducted to evaluate the uptake and accumulation of waterborne lead (Pb) in various tissues of Catla catla when exposed to lower doses. Single breed fingerlings (6-8 cm) of C. catla were obtained from a commercial fish seed hatchery. Six groups (in duplicate) of fish (40 each) were maintained at 22 C, pH 7.0, hardness 140 mg/l and DO 7.0 mg/l in 90 liters of water in glass tanks. E...
