Studies on Conditioned Responses in Fishes. Part VII. Temperature Perception in Teleosts

Abstract

By the use of a “conditioned response” technique it has been shown that teleostean fishes respond “purposively” to an increase in temperature of the water surrounding them of between 0-03° C. and 0-10° C. It is probable that the former figure is true for all the species investigated, but it has only been practicable to establish it with certainty in a few sedentary forms
