Abstract :In this study, the lethal chlorine concentrations insert ignore into journalissuearticles values(LC); and residual chlorine concentrations in water for a fouling organism, the pearl oyster Pinctada radiata insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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.
