Water quality measured during an experiment to determine the effects of pulsed direct current electrosedation on juvenile hybrid striped bass Morone chrysops × M. saxatilis. Values represent means ± SE of water quality parameters measured in water samples collected at time  =  0, 3, and 6 h from the holding recirculation system. Due to equipment sensitivity, values <0.1 are reported as 0.0. Observed variability was due to replacing water lost when recirculation system filters were backflushed during the course of the experiment.
