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 treatments. Number
over vertical bar is conductivity in mmhos.
. Data on location and conductivity are values
24 hr after start of experiment. N = 40
4-cm fish/replicate tested at 12°C .......................... 50
17. Relative frequency distribution in 8 compartments
of the TDS gradient device for pooled data for
8-12-cm humpback chubs tested at 18°C (I, II)
and 4-cm chubs tested at 12°C (III). Numbers
above vertical bars are the range of conductivity
(mmhos) for that compartment for 2 or 3 replicates
(Figures 13, 14, and 15) .................................... 51
