Copepods Salmincola prevalence appears to increase with the duration of time spent in reservoirs. Copepod infection seems rare in stream-rearing juveniles. Need information on how copepods affect saltwater transition (physiology, parasitology). Need standardized protocol to record intensity of infection. Are fish infected in the reservoir? Do Salmincola negatively affect survival? Species Composition Large abundance of piscivorous predators in Lookout Point Reservoir. Currently processing diet samples collected in Spring and Fall 2011. Drawdown in Lookout Point could decrease abundance of predatory fish. Downstream effects? Detroit Reservoir - Hatchery Rainbow Trout prey on juvenile Chinook stream, reservoir, below the dam
