Abstract Groups of Eurytemora affinis were held in flow-through chambers and exposed to ambient water from moderately (Station 1) and heavily (Station 2) polluted sites in Chesapeake Bay tributaries. A control group was held in identical chambers supplied with water from a clean site. Survival, growth and reproduction were assessed after 10 days exposure. At the moderately polluted site, an additional treatment consisting of a 50∶50 mix of control and ambient water was also run. Survival of E. affinis was not a reliable indicator of water quality. Growth was indicative of water quality at each station, but not between stations. Relative fecundity was the best indicator of water quality within and between stations. At Station 1, the relative fecundity was 2.6, 4.2 and 10.0 in ambient, 50∶50 mix and control water, respectively. At Station 2, the relative fecundity was 0.8 and 10.0 in ambient and control water, respectively.
