Abstract

This study was undertaken to determine acute toxicity level (median lethal concentration) of copper to goldfish
Carassius auratus Linnaeus, a freshwater cyprinid. The experiment was conducted in filtered (mesh size I urn)
freshwater having total hardness 34.2 (as CaC03) in a static condition. Copper sulphate (CuS04 5HP) was used as
a source of copper. The LCso values of copper were determined from probit values of cumulative mortality percentage
against exposure concentrations (dose response) using simple linear regression model Y =a + bX. The LCso values
of copper to goldfish (10.5 ± 1.43 g) were determined as 0.44 ± 0.06, 0.36 ±0.04,0.20 ±0.03,0: 19 ±0.02,0.15 ±
0.02 and 0.14 ± 0.02 ppm for 12,24,48,72,96 and 120 hr. respectively.
