Figure 11. Longitudinal variation in mean body condition (Kn) of bluehead sucker,
flannelmouth sucker and roundtail chub. Colorado River fish data were pooled by strata into
four major river segments as indicated; the one Gunnison River stratum is also shown. Means
were first calculated for each of the three sampling periods for which data were collected in all
strata (fall 1994, spring 1995, fall 1995), and the mean of these means was then calculated.
Error bars represent the 95 % confidence interval.
