Table 6. Overall and pairwise ANCOV A tests to determine differences between feeding

treatments for larval razorback suckers. A). Analysis of covariance of lo~

sagittal diameter as a function of larval razorback sucker TL among feeding

treatments. B). ANCOV A between Ad libitum and Starved larvae C).

ANCOV A between Ad libitum and Suboptimal larvae. D). ANCOV A between

Suboptimal and Starved larvae. Tests are for equivalency of intercepts and for

homogeneity of slopes. ........................................... 49

Table 7. Least squares analysis of sagittal diameter as a function of known age for larval

razorback suckers reared at Ad libitum, Suboptimal and Starved feeding levels.

The equation for the regression is sagittal diameter = intercept + slope (known

age). .......................................................... 51

Table 8. Analysis of covariance of sagittal diameter of larval razorback suckers as a

function of AGE among feeding treatments. A significant difference in the

variable FEED indicates a difference in intercepts between treatments. A

significant AGE*FEED interaction indicates different slopes for the regression

lines. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. 52

Table 9. Repeated-measures analysis of variance for TL2 for razorback sucker larvae at

140C. Repeated measure is LOC (tank). Treatment effect uses LOC(TREAT)

type ill MS for the error term. Differences at each date are measured using a

Tukey multiple comparisons test of means. Asterisks (*) denote means not

significantly different from one another. .............................. 83
