The adaptation kinetics of TH and TC upon sharp change of the water temperature from 20 to 30 °C of Danio rerio. Abscissa, the adaptation time, hours. Experimental values of the heat shock temperature, TH, are shown by open circles (○) and the values of cold shock, TC, by filled circles (●). Horizontal lines indicate the values of TH and TC after a prolonged acclimation at 20 °C and at 30 °C
