Striped bass were transposed from a soft water hatchery to a hard water facility and recovered for one month in either 1.0% sodium chloride, 0.1% calcium chloride of freshwater. The addition of 1.0% sodium chloride to the transportation and recovery waters of striped bass increased survival, decreased plasma cortisol and glucose levels, and reduced osmoregulatory dysfunction when compared to fish transported and allowed to recover in 0.1% calcium chloride or freshwater. Water containing 0.1% calcium chloride did not reduce transport-induced stress when compared to freshwater. The presense of 1.0% sodium chloride in the transportation and recovery water reduce the above stress responses and increased survival of striped bass following transport. The presence of 0.1% calcium chloride was unable to provide a protective effect compared to freshwater.
