CaCl2 was used to increase the total hardness of water in three ponds from 20 to 45-100 mg/l as CaCO3 5 days before harvest. CaCl2 was used to increase hardness from 10 to 70-200 mg/l as CaCO3 in water used for holding and transporting fish after they were harvested from ponds. All groups of fish in water containing additional calcium had 80-99% survival compared with 16% survival for a group of fish without additional calcium in the water before or after harvest. Addition of 1% CaCl to the water did not increase survival.
