Conclusions
Growth modulation successfully reduced minijack rates
It also significantly reduced both juvenile and adult survival-size matters
The Yakima HxH line shows consistently lower minijack rates than the supplemented line.
High numbers of minijacks appear to migrate downstream in the spring
Increased egg incubation temperatures significantly alter life-history composition-global climate change effects?
Further research is needed to develop hatchery rearing protocols that will not alter life-history composition of hatchery stocks
