White amur TL measurements were highly
variable over time but were all >_ 360 mm TL
(Fig. 15). To comply with AGFD white amur
stocking permit conditions, SRP must stock sterile
white amurs with a minimum head width of 57.2
mm. Due to low sample sizes and the wide range
in TL, distinct cohorts were not apparent except
for 1 in Spring 1994 (TL 440 to 560 mm). Over
time, we found white amurs showed some degree
of growth due to the upward shift of TL.
Due to low sample sizes, the yellow bass and
roundtail chub length frequency distributions
were plotted across seasons. We found 2 cohorts
of yellow bass (Fig. 16) with peaks at 90 mm and
230 mm TL. We identified 2 separate cohorts of
roundtail chubs with peaks at 170 mm and 250
mm TL (Fig. 17).
