THE ACUTE TOXICITY OF NaOCl ON ZEBRAFISH (Danio rerio Hamiton, 1822), TIGER BARB (Puntius tetrazona Bleeker, 1855) AND VARIABLE PLATY FISH (Xiphophorus spp.)

Abstract

: In this study, NaOCl is used as a pollutant to test acute toxicity LC50 on Zebrafish, Tiger barb fish and Variable platy fish, which will make a foundation for early warning and bio-moninitoring of water pollution. The results have shown that when fish are exposed to different concentrations of NaOCl, their behaviours such as fast swimming, rushing into sides of aquarium, jumping out of water, then dying happen The change of behavior depends on exposure time and concentration of NaOCl, the Zebrafish is the most sensitive with LC50 = 58.00 mg/l, Tiger barb fish is 80.05 mg/l and Variable platy fish is 84.16 mg/l. The Zebrafish is used to monitor water at low level pollution, while the Tiger barb fish and Variable platy fish are used for monitoring water at high level pollution.
