Abstract :ABSTRACT Mercury is one of the most harmful heavy metals, present in many aquatic media. This study was aimed to determine the acute toxicity of   mercury-II-chloride and behavioral changes in    Leuciscus cephalus insert ignore into journalissuearticles values(L., 1758);. Leuciscus cephalus were selected for the bioassays experiments and caught in Kirmir branch of Sakarya river. Behavioral changes at each mercury-II-chloride concentration were recorded. The experiments were repeated 3 times. Water temperature was regulated at 22±1 o C. The 96-h LC 50 value of mercury-II-chloride insert ignore into journalissuearticles values(HgCl 2 .H 2 O); on Leuciscus cephalus was found to be 0.55 mg/L insert ignore into journalissuearticles values(0.53-0.57); according to Probit Analysis. There were significant changes observed in the behavior of the fish as the concentration of the toxic compound increased.   Key Words: Leuciscus cephalus; Mercury-II-chloride; Lethal concentration; Bioassay
