In this study the structure and diversity of the endohelminth community, as well as its interactions with 73 specimens of Piaractus mesopotamicus are described. The fish were caught in Aquidauana and Miranda rivers, both located in the Pantantal region, in the state of Mato Grosso do Sul. A total of 608,788 specimens of helminthes were found, representing five species: Dadaytrema oxycephala, Ch...

This study was carried out to determine the toxicity and biochemical morphophysiological changes caused by Serjania erecta leaf aqueous extract in pacu (Piaractus mesopotamicus). For acute testing (CL50-4h), juveniles were exposed during 4 h concentrations of 2.5, 12.5, 25, 50, 100, 150 µg mL-1, which added directly water tanks. In control group, animals kept free from extract. CL50-4 estimated...

O estudo teve como objetivo determinar a atratividade e palatabilidade de níveis inclusão proteína hidrolisada penas em rações para juvenis tambacu (Colossoma macropomum Piaractus mesopotamicus). As seis dietas foram formuladas acordo com as exigências nutricionais da espécie, nas quais: controle positivo sem hidrolisado (PHP0), proteico 1% (PHP1), 2% (PHP2), 3% (PHP3), 4% (PHP4) 5% (PHP5).
