Summary of variables (fixed effects) tested in linear mixed models for their independence in explaining variability among plasma cortisol, glucose and potassium concentrations in yellowfin bream (Acanthopagrus australis).

For each blood parameter, three models were applied to the trawled fish only (all individuals, and then just those sampled immediately after sorting—T0 and then after five days in cages—T120), and a fourth model applied to trawled (from conventional and water sorting) and control fish at T120 (defined as ‘treatment of fish’). -, term not appropriate in the model. The river salinity and temperature were bottom readings.○ p > 0.05;*p **p Summary of variables (fixed effects) tested in linear mixed models for their independence in explaining variability among plasma cortisol, glucose and potassium concentrations in yellowfin bream (Acanthopagrus australis).
