Figure 2. Thiosulfate was not able to increase the rate of depuration of
Ag from the gills (A). Although not statistically
different, there was a tendency for plasma Cl to increase at the end of the
depuration period (B). This
increase in plasma Cl may indicate the ability of the fish to recover ionoregulatory
function once in Ag-free
water without necessarily removing Ag from the gills.
