FIGURE 2 in The thermal dependence of the protein-sparing effect in rainbow trout (Oncorhynchus mykiss, Walbaum 1792)

FIGURE 2 Ammonia quotient (AQ) of rainbow trout (Oncorhynchus mykiss) fed three isonitrogenous diets with different energy contents [high energy (HE) = 20.50 MJ kg 1, medium energy (ME) = 18.76 MJ kg 1, low energy (LE) = 17.35 MJ kg 1) at five temperatures (12 C, 14 C, 16 C, 18 C, 20 C). A quadratic dependency model was used to analyse the data. Parabolas describe the quadratic dependency of AQ values on temperature. Calculated lowest AQ values for each parabola are marked with a cross (). Each data point represents the measurement of one tank with rainbow trout at each respective diet and temperature. (n = 3)
