Teflubenzuron as a tool for control of trichodinids in freshwater fish: Acute toxicity and in vivo efficacy.

In this study we describe the anti-Trichodina effects of teflubenzuron (TFB) for Oreochromis niloticus and for Piaractus mesopotamicus. We also evaluated the acute toxicity, for both species, by using TFB in the concentrations of 700.0, 800.

Histopathological biomarkers in pacu (Piaractus mesopotamicus) infected with aeromonas hydrophila and treated with antibiotics.

Pharmacochemicals usage in fish farming disease treatment can cause morphological and functional changes in absorption capacity, metabolism and excretion organs. The aim of this research was to evaluate the histopathological biomarkers in the gills, liver, kidney and skin of pacu (P. mesopotamicus), which have been infected with A.
