摘要: Fish in aquaculture are often exposed to various stressors that may change their ability survive or limit growth. Amino acids used for processes other than growth, including stress response. This study intended analyse how repeated acute handling can affect growth and amino acid requirements fish. Senegalese sole juveniles were weekly held the air during 3 min (Handling) 9 weeks; Control groups left undisturbed. Growth plasma levels of indicators free assessed at end experiment. Plasma cortisol osmolality showed fish Handling treatment stressed, but was unaffected. concentrations indicate stressed altered, which probably reflects synthesis proteins specific compounds related
