Abstract
The Guilan province in the north of Iran has witnessed a rapid industrial development in recent years causing pollution of water resources in rivers, wetlands and the Caspian Sea coastal areas. We studied the acute toxicity of Copper and Lead in kutum fingerlings through acute toxicity and M.A.C value determination in summer and autumn 2006. A total of 21 aquariums with a capacity of 30 liters each stocked with 10 fingerlings were used in our experiments with the two metals. Six aquaria and six concentrations of Cu and Pb composed the 18 treatments while 3 other aquaria were used as control. For each treatment, three replications were conducted. The relevant physical and chemical parameters of water during the experiments were measured including pH which was in the range 7-7.5, DH=200-250mg/l (CaCO sub(3)), DO= 80% and temperature which was recorded as 24 plus or minus 1C. Fish investigations were conducted in 24 hour intervals. The results indicated that the lethal concentration (LC s.....
