Fig. 1. Plasma osmolality (mOsmol kg1) of Arctic char, Atlantic
salmon and rainbow trout acclimated to freshwater (control) or seawater
(32
) for up to 30 days. For clarity only one control time point (1 day
freshwater, FW) is included for each species as it was not significantly
different from the corresponding 30 day freshwater group. *Significantly
different (P<0.05) from both freshwater control groups;
asignificantly different (P<0.05) from corresponding 2,
4 and 10 day seawater groups, but not different from either freshwater control
group; bsignificantly different (P<0.05) from
corresponding 4 day seawater group, but not different from either freshwater
control group. See text for interspecies comparisons. Values are means
± s.e.m.; sample size ranged from 5 to 8, and is listed in Results.
