A field experiment conducted in August 2005 that compared the survival of trout fry (newly hatched fish) exposed to constant versus varying metal concentrations, Dry Fork Belt Creek, Mont. Water stored in the streamside tanks was used to periodically refresh the water in the plastic containers in the stream. Water in the tanks had high, medium, or low metal concentrations. The fourth tank contained metal-free water used for the experimental control. The most upstream group of containers (at bottom of photo) were perforated so that metal concentrations in these containers would fluctuate as they do in the stream -- from the Diurnal Metal Variations Photo Gallery
