摘要: In this assay the effect of consecutive stress handling and carrageenin injection (500 µg in 0.5 ml saline solution) or mL on Piaractus mesopotamicus Holmberg, 1887 (Osteichthyes: Characidae) was evaluated. The fish were subjected to 30 s capture applied repeatedly at 60 min intervals over 6 h. Blood sampling as following: time 0: basal blood first stress; 1: with after 5 min; 2: 3: 4: 5: 90 min. Circulanting cortisol levels showed significant decrease 4 both carageenin injected fish. fish, glucosis increased 2 while fact occurred 3. An increase special granulocitic cells lymphocitopenia observed 2. Neutrophilia reported
