title: Temperature preference of the crayfish Orconectes obscurus.
abstract: Acclimation temperature influenced the acute preferred temperature of the crayfish Orconectes obscurus. This species preferred a higher temperature than its acclimation temperature for those acclimation temperatures ranging from 6 degrees to 26 degrees C. When acclimated to 30 degrees and 33 degrees C, the crayfish preferred a lower temperature than its acclimation temperature. The final temperature preferendum is estimated to be approximately 30 degrees C.
