The certain objectives of our study had been to (1) evaluate isotopic Yampa River, Colorado. The precise objectives of our study were to (1) compare isotopic signatures from two reservoirs inside the Upper Yampa River which can be possible sources of signatures from two reservoirs inside the Upper Yampa River which can be possible sources of northern pike recruitment inside the Yampa River and (two) estimate temporal variation in northern pike recruitment within the Yampa River and (two) estimate temporal variation in isotopic data. isotopic data. two.

Otolith Collection and ProcessingAge-0 northern pike have been collected making use of either boat electrofishing or seines. We Age-0 northern pike had been collected making use of either boat electrofishing or seines. We assumedthat age-0 northern pike collected in our study have been captured inside the reservoir in assumed that age-0 northern pike collected in our study were captured within the reservoir in which they hatched, and we believe that this can be a affordable assumption for the following which they hatched, and we believe that this is a affordable assumption for the following reasons. To come to be entrained in dam releases, age-0 northern pike would have to move causes. To grow to be entrained in dam releases, age-0 northern pike would must move long Croverin MedChemExpress distances by means of unsuitable habitats, which unlikely as it is known that age-0 long distances through unsuitable habitats, which isis unlikely since it is identified that age0 northern pike stay close to vegetation for protection and meals [59]. Offered that Lake northern pike stay close to vegetation for protection and food [59]. Offered that Lake Catamount lies downstream of Stagecoach Reservoir, age-0 northern pike could Catamount lies downstream of Stagecoach Reservoir, age-0 northern pike could potentially emigrate emigrate from Reservoir Reservoir into Lake As a result, Thus, fish potentiallyfrom Stagecoach Stagecoachinto Lake Catamount.
