We found that by the time age 4 adults returns from BY 2002 arrived at RAMF the Low and High growth treatment differences in juvenile length- and weight-at-release shown in Figure 2 no longer exist. In no case was there a significant Treatment or Acclimation site effect, nor were there significant interactions. We also found that age 3 returns from BY2002 demonstrated no significant Treatment effect, but did find significant Treatment effects in age 2 returns from both BY2002 and 2003. Age 2 precocious males were sampled approximately 6 to 8 months after release
