In Exp. 1, all LHC levels reduced cortisol concentrations ( I p i = 0.0026) (Figure 1a), while in Exp. 2, LHC did not affect cortisol after 15 and 30 days ( I p i > 0.05) (Figure 2a,c). In conclusion, levamisole hydrochloride reduced blood cortisol concentrations in tambaqui with higher parasitic infection, activated the complement system in stressed fish and potentiated the stress response. The high level of infection probably influenced the reduction in cortisol levels in fish fed with LHC, as lower levels were not found in fish less infected. [Extracted from the article] |
