Abstract :In this study, the lethal chlorine concentrations (LC) and residual chlorine concentrations in water for a fouling organism, the pearl oyster Pinctada radiata (Leach, 1814) [Avicula], were investigated during May 1999-April 2000. The study was carried out under laboratory conditions at 20ºC. Acute toxicity tests were conducted under a flow through system by using continuous application of chlorine according to bioassay test methods. Test solutions were made by using an appropriate amount of sodium hypochlorite (NaOCl-). According to the results, the 24h-LC50 was 1.75 mgl-1 and the residual chlorine was 0.47 mgl-1 for LC50 of Pinctada radiata.Keywords : Pearl Oyster, Pinctada radiata, Bioassay, Acute Toxicity, LC50, Residual Chlorine
