Table 3: General linear model analyses (GLM, type III, unbalanced ANOVA) of the effect of temperature category (low=8 and 13°C, high=18, 23 and 27°C) and experimental round (1a, b and c for high temperatures and 2a and b for low temperatures) on growth (SGR and TGC) and feed intake (% of BW1) of Eurasian perch (Perca fluviatilis) from the temperature study. For the general analysis (only temperature categories), tank number was used as a nested factor. In the table are degrees of freedom (df) and F- and P- values for growth rates (SGR and TGC), feed intake and energy requirements (DEN) demonstrated.
