Na+1, Na+2: plasma sodium concentration at first and second challenge respectively.

Cl-1, Cl-2: plasma chloride concentration at first and second challenge respectively.

Final gill weight and body weight measured 2 months after the end of the second challenge.

SD: overall standard deviation; n: total number of individual records.
