Figure 1: Box-plots of growth rates (SGR and TGC), feed intake (% of BW) and energy requirement (DEN, kJ DE•g-1) of Eurasian perch (Perca fluviatilis) in different temperature categories (8, 13, 18, 23 and 27°C). Square symbols within boxes represent the median of the sample (white square symbols for SGR and black square symbols for TGC), boxes represent quartiles and the whiskers show non-outlier range. Identical lower and upper case letters indicates no significant differences (P>0.005) between temperature categories. For growth rates (SGR and TGC) and feed intake, number of replicates in temperature categories 8-23°C were six and in category 27°C five. For the energy requirement (DEN) data, numbers of replicates were four in temperature category 8 and 13°C, and six in categories 18 and 23°C. |
