A study of the hematological parameters, glycogen, glucose, and lactate, and the activity of malate and lactate dehydrogenases was carried out in blood and tissues of fishes submitted to two, four, and six hours of hypoxia and recuperation. Only after 4 h of hypoxia was there a drop in liver glucose. Alter 16 h, a drop in lactate and a rise in glucose in practically all tissues signaled a recup...

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...

Abstract The objective of this work was to evaluate the effects dietary supplementation with fructooligosaccharides (FOS) on performance, hematology, and immunology pacu (Piaractus mesopotamicus) juveniles. A total 0 (control), 2.0, 4.0 g kg-1 probiotic were added fish diets. Fish (49.3±4.3 g) allotted into 12 tanks 60 L, in a completely randomized design (n=4). After days, final weight, weight...
