V.K. Golovanov, D.S. Kapshaj. The responses of the juveniles of some fish species to a continuons water temperature rise // Transactions of Karelian Research Centre of Russian Academy of Science. No 5. Experimental biology. 2014. Pp. 95-101
Keywords: fish, behavior, locomotory activity, behavioral responses, acclimation temperature, heat tolerance, water heating, critical thermal maximum, lethal temperature.
The behavioral responses to continuons heating at a 9 °C/h rate were analyzed in juveniles of four fish species – common carp, roach, perch and Amur sleeper. All the fish were acclimated to two levels of temperature – 18 ± 2 °C and 28 ± 1 °C. For the first time, the differences befwern species in the nature of horizontal (jerks) and vertical movements (ascent to the surface) of the fingerlings were identified under experimental conditions with a rising ambient temperature. These data can characterize the locomotory activity of fish at abnormally high temperatures.
