The kinetics of temperature adaptation of Danio rerio. Abscissa, adaptation time (t) in the logarithmic scale; ordinate, shock temperatures TH(○), TH(◊), TC(●), TC(♦). Experimental values of TH are shown by open symbols (○ and ◊) and values of TC, by filled (black) symbols (● and ♦). The shock temperatures recorded after the transfer of the fishes into water with higher temperatures are designated with circles (○ and ●) and shock temperatures recorded after the transfer of the fishes into water with lower temperatures, with diamonds (◊ and ♦). Horizontal lines show the stationary values of TH and TC calculated on the basis of linear regression, with regard of the values of shock temperatures in the range from 20 °C to 30 °C: TC = 0.70 TA—4.12, TH = 0.53 TA + 24.20. The letters A, B, C, D, E and F indicate the kinetics of adaptation in different temperature ranges
