Evaluation of experimental infection with Aeromonas hydrophila in pacu (Piaractus mesopotamicus) (Holmberg, 1887)*
The aim of this work is to determine the concentration of Aeromonas hydrophila to be inoculated in pacu (Piaractus mesopotamicus), so as to induce bacterial infection but not death during a period of at least ten days and, therefore, enable the development of treatment protocols. The tested concentrations were established through the Mac Farland scale and fish were subjected to three A....

The effects of replacement of soybean meal by shrimp shell meal on the growth of hybrid tilapia (Oreochromis niloticus x Oreochromis aureus) reared under brackish water
To evaluate the effects of complete replacement of soybean meal (SBM) protein by shrimp shell meal (SSM) on the growth performance of hybrid tilapia (O. niloticus x O. aureus), five approximately isoenergetic and isonitrogenous (30% crude protein) diets containing 0, 33, 50, 67 and 100% SSM were fed to triplicate groups of ten fry with an initial mean weight 1.54 ± 0.03 g/fish under brackish water (15...
