Introduction

Physical stressors associated to intensive fish production (injuries, manipulations and handling) are low but continuous. Those processes usually derive in a chronic stress situation involving suppressive effects on the fish immune system, disease resistance and energetic metabolism as result of the allostatic load imposed to the organism (Tort, 2011). These adverse effects have been mainly associated with increased secretion of cortisol by interrenal cells via activation of the HPI axis (Vijayanet al., 2005).
