The toxicities of various metals to Moina macrocopa were investigated by the static bioassay method. The 24-h and 48-h LCso for the metals were as follows: nickel nitrate 2.201 and 0.461 mg/1, lead nitrate 1.120 and 0.755 mg/1, zinc sulphate 0.246 and 0.094 mg/1, cadmium nitrate 0.218 and 0.013 mg/I , cupric nitrate 0.019 and 0.017 mg/1, and mercuric nitrate 0.003 and 0.001 mg/1, respectively. The yeast-algal method was successfully used in culturing Moina. The data may be useful for the planning of water quality criteria and bioassay toxicity tests of industrial wastes in the regions where M. macrocopa is found abundantly.
