Resumo: Stressful husbandry conditions are likely to a¡ect growth and amino acid metabolism in ¢sh. In this study, chronic ammonia exposure was used to test the e¡ects of a stressor on growth and amino acid metabolism of Senegalese sole juveniles. The ¢sh were exposed for 52 days to 11.6 mg L 1 [low-TAN (L-TAN)] or 23.2 mg L 1 [high-TAN (H-TAN)] of total ammonia nitrogen (TAN), or to 0 mg L 1 (Control). Growth in L-TAN groups was slightly but signi¢- cantly di¡erent from the Control groups [relative growth rate (RGR50.35 0.13 and 0.52 0.23% day 1respectively)]. In H-TAN groups, growth was severely a¡ected (RGR50.01 0.13% day 1 ).
