RESUMO

The physiological and biochemical status and characteristics of fishes of different taxonomic groups under the impact of elevated water temperature have been investigated. Perch and carp differently responded to the thermal factor at biochemical level. As temperature rises, the hormones level in perch remained almost the same, in carp it changed. Activity of the energy metabolism enzymes in perch showed deceleration of catabolism in tissues, this was also confirmed by glucose content. In carp such changes caused activation of catabolic reactions. Dependence was revealed of the energy metabolism reactions in both fish species on oscillatory elevations of water temperature. The obtained results regarding changes of biochemical parameters in carp and perch indicated species specificity of their response to untypical changes of thermal conditions.
