University of Minnesota; 1978.https://hdl.handle.net/11299/166187The movement patterns of four fish species, yellow perch (Perea flavescens), northern pike (Esox lucius), largemouth bass (Micropterus salmoides) and walleye (Stizostedion vitreum) were monitored with radio telemetry methods near the thermal discharge of a power plant, (6 T 15°c nominal). A minature temperature sensing transmitter and an automatic recording system were developed for use with yellow perch. Fish movements relative to depth, temperature, center of the home range, discharge point, and release location are examined. Near thermally altered areas northern pike exhibited the greatest amount of movement followed by yellow perch, walleye and largemouth bass. Except for largemouth bass, thermal experience was found to be transitory. An overa11 winter temperature preference of 5.4°c was determined for yellow perch. I concluded that temperature, when in concert with numerous other environmental variables, did not alter the distribution of yellow perch to that predicted on the basis of laboratory temperature preference studies.Thesis or Dissertation
