Daphnia magna, the crayfish Pacifastacus leniusculus, and nymphs of the stoneflies, Acroneuria californica, A. pacifica, and Pteronarcys californica were tested in the laboratory to determine their survival in different concentrations of air-supersaturated water. The mean 96-h LC50 value (lethal concentration, 50% mortality) for D. magna was 122.5% total air saturation. The 7-day LC50 was 120% and the 10-day LC50 was 117.5%. The mean 96-h LC50 for crayfish was 147% total air saturation. The 7-day LC50 was 145% and the 10-day LC50 was 133%. The 10-day EC50 values (effective concentration, 50% immobilized) for stoneflies were 135% for A. californica and greater than 125% for A. pacifica and P. californica. Bubbles (emboli) were observed in body fluids and tissues, and general body distention occurred before death in Daphnia, crayfish, and stoneflies. Lethal threshold concentrations for Daphnia and crayfish were near 111 and 127%, respectively.
