FIGURE 4.-Somatic (total length, TL) and otolith (J..Lm) growth patterns of Colorado squawfish larvae in (A)
constant and (B) fluctuating temperature conditions centered on 220([:. Fish were II d old at the start of the experiment
(day 0). Treated fish were fed for 6 d, starved for 6 d (interval between arrows), fed for 6 d, and preserved, Error
bars about means are :':2 SE (N = 8). .

lith diameter to age also differed between fast- and
slow-growing fish. Otolith growth was more con-
servative than somatic growth; in regressions of
squared total length (Figure 2) or squared lapillus
diameter (Figure 3) versus age, slope differences
