Abstract
Brook trout were acclimated heterogeneously for 3 weeks by exposing the head and tail simultaneously to two different temperatures. Time to death at a lethal temperature was taken as a measure of resistance acclimation. The relation between the resistance acclimation and mean temperature of the whole fish during acclimation indicated that the response of the whole organism depends on the mean thermal history of the total tissue regardless of the anatomical site. The mechanism through which a fish can acclimate to a higher or lower level of temperature is still unknown and whether the central nervous system has a direct or indirect role on such acclimation is not yet clear.Keywords
