Yellow perch, movement, dispersal, lake, seasonal
Movement of yellow perch (Perea flavescens) from Lake East Okoboji into Lake West Okoboji was confirmed. Recapture trends suggested general movements into Lake West Okoboji in autumn and return into Lake East Okoboji before spawning in spring. Thermal gradients occurring due to seasonal differences in direction of interlake flows and differential warming and cooling rates of the two lakes, appeared to be major ecological factors that governed these interlake movements.
