15 are values 24 hours after start of experiment.
N = 20, 8-12 cm fish/replicate. Concentrations
were double those of previous tests . . . . . . . . . . . 217
16 Relative frequency distribution of juvenile
humpback chubs in 8 compartments to TDS
gradient device (Figure 2) with and without
gradient established. Numbers I, II, and
III are replicates for controls and treat-
ments. Number over vertical bar is conduc-
tivity in mmhos. Data on location and
conductivity are values 24 hours after start
of experiment. N = 40, 4 cm fish/replicate
tested at 120 C . . . . . . . . . . . . . . . . . . . . . 218
17 Relative frequency distribution in 8 compartments
of the TDS gradient device for pooled data
for 8-12 cm humpback chubs tested at 180 C
(I, II) and 4 cm chubs tested at 120 C (III).
Numbers above vertical bars are the range of
conductivity (mmhos) for that compartment
for two or three replicates (Figures 13, 14, and 15) 219
