The Daphnia 21-d juvenile production test was ring tested in 1985. The results showed maximum variability, that is, the effective concentration ranged from less than the lowest concentration to greater than the highest concentration. At a workshop on this subject in 1989 several contributory factors to this variability were identified. This paper describes two experiments designed to investigate these factors, specifically the species of algae supplied as food, the ration, the age of algal… Expand
