Mean whole body composition of Atlantic salmon juveniles fed non-GM maize or <i>Bt</i>-maize without or with soybean meal (SBM) for 99 days.

Means and pooled standard errors (pSE) were calculated from pooled samples of 20 fish per tank, three replicate tanks per treatment group (n = 3). The p values are given for the main variables non-GM/GM and non-SBM/SBM inclusion, respectively, as well as p values for interactions between the variables by two-way ANOVA analysis. *Gross energy was calculated using the energy concentrations of 39.5 for lipid, 23.6 for protein, and 17.2 kJ/g for glycogen (glycogen levels were calculated as: 100 – (water + crude protein + crude lipid + ash).
