Table 3 Effects of dietary electrolyte balance (DEB) and dissolved oxygen levels (DO) on the apparent nutrient digestibility in trout. DEB in mEq kg⁻¹. Parameters are expressed as %. Mean values per tank (n = 3), measured in 30 fish. Further details are provided in Methods. Pooled standard error of mean (SEM); Interaction (I); Not significant (ns) P > 0.1; *P < 0.05; **P < 0.01; ***P < 0.001.
