Fig. 2. Time-course of whole-body calcium influx rate in fish maintained at 100%SW
(filled circles) and in fish transferred to 50%SW (open circles) for a 16-h
period. Each point is the mean least squares adjusted for body mass
(1050 mg), and the vertical lines are their standard errors. Asterisks
represent statistically significant differences to 100%SW
(*P<0.01; **P<0.001) at a given
time.
