Resumo: Fish held at high stocking densities are generally exposed to chronic stress situations that impose severe energy demands and may predispose the ¢sh to infection. Senegalese sole Solea senegalensis (Kaup) juveniles (78.8 18.9 g body weight) were maintained at low (LSD; 4 kg m2 at the end of the experiment), medium (MSD; 9 kg m2 ) and high (HSD;14 kg m2 ) stocking densities during a period of 63 days. Although disease outbreaks were observed in ¢sh reared at HSD, growth and food consumption did not vary among di¡erent treatments. Results from plasma cortisol and free amino acids (FAAs) showed signi¢- cant di¡erences among di¡erent rearing densities pointing to HSD as stressful rearing condition.
