Table 1--1. Population estimates (number/ river km) of adult Gila
cypha (> 150 mm TL) in three reaches of the Little Colorado River
(Confluence, Powell, Salt) from July, 1991 through December,
1992. Estimates were adjusted before analysis for length of reach
(in km). Loglo fishing effort was used as ANCOVA covariate.
Diagonal elements represent average least squares population
estimates (adjusted for loglo fishing effort), and have been
converted from loglo values. Upper triangular cells represent
F-values for pairwise a priori contrasts.
