Table 6-Analysis of covariance for growth rate (mm/month) as a function of logo total <br />length (mm) of humpback chub during first and second growing seasons after initial <br />capture. Probability values for the intercept tests are differences in means between <br />groups (gear) designated by the indicator variable (first or second growing season) after <br />adjustments were made for the covariate (log,o total length). The interaction term tests <br />whether slopes were equal between groups (gear). <br />Sum of <br />Effect df squares F P RZ <br />1$t growing season after initial capture <br />Slope test <br />logo Length 1 57.92 10.36 0.002 0.20 <br />Gear 1 23.13 4.14 0.05 <br />logo Length X Gear 1 21.53 3.85 0.05 <br />2"d growing season after initial capture <br />Slope test <br />logo Length 1 5.30 8.20 0.007 0.31 <br />Gear 1 0.16 0.25 0.62 <br />logo Length X Gear 1 0.15 0.22 0.64 <br />Intercept test <br />logo Length 1 9.50 15.03 0.0004 0.31 <br />Gear 1 0.47 0.75 0.39 <br />19 <br />
