A study was conducted with Daphnia magna to determine the effect of neonate weight loss or lack of weight gain on experimentally derived copper 48‐h LC50s. Standard unfed tests as well as algal‐fed ( Selenastrum capricornutum ) tests were used to look at weight loss and gain. No significant relationship was found between amount of weight loss and copper LC50s. However, dry weight of unfed and algal‐fed control organisms could be used to predict total copper LC50s.
