In the Colorado River, C/E for Colorado squawfish was significantly
correlated with C/E for sand shiner, red shiner and fathead minnow in
backwaters and in all habitats combined (Table 3), and with fathead minnows
and channel catfish in runs. In contrast, C/E for red shiner and sand shiner
in the Green River were not significantly correlated with that for Colorado
squawfish (Table 4). The C/E for fathead minnows in backwaters and in all
habitats combined, and for channel catfish in runs, shorelines and all
habitats combined were significantly correlated with that of Colorado
squawfish. However, most of these correlation coefficients were low {Table
4).
