摘要：Spawning movements and the factors affecting those movements are often of interest to fisheriesmanagers and biologists. The objective of this study was to examine the influence of environmentalfactors on the movements of an adfluvial Rainbow Trout Oncorhynchus mykiss population in the BlackHills, South Dakota. Three unique strains of hatchery-reared Rainbow Trout and resident RainbowTrout were implanted with passive integrated transponder (PIT) tags and movements between DeerfieldReservoir and the Castle Creek tributary system were monitored from August, 2010-July, 2011. Initialadfluvial movements of Rainbow Trout were detected using a stationary PIT tag reader deployed nearthe mouth of Castle Creek. Multiple linear regressions were used to model the relationship between PITtaggedRainbow Trout movement and water temperature, photoperiod, and discharge. Using Akaike’sinformation criterion (AIC) to compare models, discharge was the top supported model explainingvariation in Rainbow Trout movement. Additionally, models containing temperature and photoperiodwere also supported. Supported models only explained moderate levels of variation (<23%) in RainbowTrout movement. Understanding how environmental variables affect the movement patterns of thisunique population is essential in determining the proper management strategy for the Deerfield Reservoirsystem..
