Objectives and Tasks

Objective Task
1. Determine aquatic plant species composition and site characteristics of vegetated habitats in the John Day Reservoir. a. Collect and preserve representative samples of aquatic macrophyte species for later identification and verification.
1. Determine aquatic plant species composition and site characteristics of vegetated habitats in the John Day Reservoir. b. Measure depth and substrate composition as habitat indicators for aquatic macrophyte occurrence.
2. Quantify fish community composition in selected near-shore habitats of John Day Reservoir. a. Sample fishes in a range of vegetated and non-vegetated shallow littoral habitats (stratified by depth and substrate type).
3. Determine if vegetated habitats are used by juvenile salmonids. a. Examine differences in habitat use between habitat types (vegetated or non-vegetated).
3. Determine if vegetated habitats are used by juvenile salmonids. b. Determine differences in physicochemical characteristics (e.g., DO,Temp.)
4. Identify interactions between exotic fishes and juvenile salmonids in vegetated and non-vegetated habitats. a. Determine, through dietary information, if there is differential predation on juvenile salmonids among vegetated and non-vegetated habitats.

Section 7. Abstract


The proliferation of exotic and invasive fishes and aquatic vegetation in littoral zones of impounded segments of the Columbia River Basin has likely substantially modified the ecology of shoreline areas. However, no research is currently being conducted to monitor exotic species in this area, although this is an objective of the FWP. Our goal is to determine the impact of exotic fishes and macrophytes on juvenile salmonid survival in near-shore and backwater reservoir habitats. Specifically, we will examine how macrophytes influence local habitat conditions, fish community composition, habitat use by juvenile salmonids, and predation on juvenile salmonids by introduced predators. Fishes will be sampled in main-channel and backwater vegetated and non-vegetated habitats of the John Day Reservoir using light traps for larvae, and boat electroshocking for juveniles and adults. Aquatic plant species composition and habitat characteristics will be determined at fixed sample sites. Gut samples will be obtained from exotic predators, and the intensity of predation on juvenile salmonids in different habitat types will be determined. Information from this study will aid effective management of exotic species to maximize juvenile salmonid survival. Additionally, there has been much recent discussion concerning a return of the Columbia River to a more normal ?riverine? state through various changes in hydrosytem operation. Monitoring exotic species is a means of determining the success of attempts to return the Columbia River to a healthy river ecosystem with a greater proportion of native taxa.
