Figure 11.— Log TL (cm) versus log age class (years) of juvenile and adult giant kelpfish 

 (males and females). * = one fish. N = 137. Regression equation: Log TL = 1.234 + 

 G.528 (log age). F = 1,589.28, P < 0.0001. Regression equation for females only (N = 

 77): Log TL = 1.234 + 0.561 Gog age); F = 1,460.7, P < 0.0001. Regression equation 

 for males only (N = 60): Log TL = 1.235 + 0.453 (log age); F = 535.0, P < 0.001. ANCOVA 

 regression analysis of log TL for males and females (two different groups versus log age 

 class (years): F = 5.82 (P < 0.05). 



MEAN LENGTH VS. AGE OF FEMALES AND MALES 



Figure 12.— Mean TL (cm) versus age class (years) of 

 female and male giant kelpfish. Significant differences 

 between male and female mean sizes indicated. 

 * = Significant difference in t-test results (0.05 level). 

 Standard error bars shown. N = 137. Two-way ANOVA 

 with replication for mean lengths of male and female 

 kelpfish at three ages (2.0, 2.5, and 3.0 yr) showed signifi- 

 cant differences between the sexes (F = 38.52, P < 0.001) 

 and the age classes (F = 78.01, P < 0.001), but no inter- 

 action (sex x ages; F = 3.37).
