Fig. 2. Restoration of plasma volume in intact trout after 40% volume expansion with saline (A) or trout plasma (B). The solid line is a mono-exponential decay fit to data points 5-60 min after volume expansion. Pre-expansion, calculated plasma volume prior to saline or plasma infusion; actual (t=0), pre-expansion plasma volume plus volume of saline or plasma infused. Values are means + S.E.M.; N=12 for both experiments.
