THE STUDY OF THE TOXIC EFFECTS OF MERCURY-II-CHLORIDE TO CHUB Leuciscus cephalus (L., 1758)
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 (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±1oC. The 96-h LC50 value of mercury-II-chloride (HgCl2.H2O) on Leuciscus cephalus was found to be 0.55 mg/L (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.
