The toxicity of copper was compared for Daphnia magna cultured in reconstituted versus pond water and fed on trout-pellet versus vitamin-enriched, algal foods. Effects of a chronic copper stress were highly variable when animals were tested in reconstituted waters. This variability is thought to be due to variability in the quality of the distilled-water matrix. The vitamin-enriched algal food was found to be superior to the trout-granule food in culturing D. magna. Control animals lived much longer and test animals were less sensitive to a chronic copper stress. The acute and chronic toxicity of copper was also compared for four species of Daphnia. When tested in pond water and fed vitamin-enriched algae, the two largest species (D. magna and D. pulex) were significantly less sensitive to an acute copper stress than the two smallest species (D. parvula and D. ambigua). There was, however, no significant differenc in sensitivity to a chronic copper stress when reduced longevity was used as the index. Application factors for the four species varied from 0.47 to 0.62 and were not significantly different.
