This experiment was performed to study the acute toxic effects of mereuric chloride(HgCl 2 ) in goldfish (Carassius aurams). In the study, Lc₅₀ values were determined for each 24, 48, 72 ,and 96-hr and mercury bioassay during the tests were performed. in five parts gill, kidney, liver, muscle and egg. The results isummarized were as follows ; 1. In the range of acute lethal toxicity for goldfish was 0.15-1.50 mg/l and the Lc₅₀ values decreased with exposure time. 2. The Lc₅₀ values of HgCl₂ for goldfish at 24, 48, 72 and 96 hour were 0.64, 0.53, 0.46, and 0.39 mg/l, respectively. 3. In the 400 μg/l treatment group, the average levels of mercury residues in the gill, kidey, liver, muscle and egg during 96 hour were 107.02 μg/g, 8.65 μg/g, 6.87 μg/g, 0.61 μg/g, and 0.82 μg/g, respectively. 4. The mercuny residues of gill was up to 12-175 times greater than mercury contents found in the other tissues.
