  • Effects of trophic exposure to diclofenac and dexamethasone on hematological parameters and immune response in freshwater fish

    The aim of this work was to evaluate the effects of diclofenac and dexamethasone on hematological parameters and immune response in the fish species Hoplias malabaricus after trophic exposure. Fish were fed twice every week with Astyanax sp., which was submitted to intraperitoneal (i.p.) inoculation with diclofenac (0, 0.2, 2.0, or 20.0 µg/Kg) or dexamethasone (0.03, 0.3, or 3.0 µg/Kg).
