Ion fluxes and hematological parameters of two teleosts from the Rio Negro, Ama...
Baldisserotto, Bernardo; Chippari-Gomes, Adriana Regina; Lopes, Nilva Pereira; Bicudo, José Eduardo Pereira Wilken; Paula-Silva, Maria Nazaré N.The aim of this study was to describe the effect of hypoxia on whole body ion fluxes and hematological parameters in two Amazonian teleosts: Serrasalmus eigenmanni and Metynnis hypsauchen. The increase of Na+ and Cl- effluxes on M. hypsauchen exposed to hypoxia may be related to an increase of gill ventilation and effective respiratory surface area, to avoid a reduction in the oxygen uptake, and/or with the dec...

Mesquita-Saad, Lenise Socorro B.; Leitão, Marco Aurélio B.; Paula-Silva, Maria Nazaré N.; Chippari-Gomes, Adriana ReginaLepidosiren paradoxa (pirambóia) is the single representative of Dipnoan (lungfish) in South America. This species is considered a living fossil, in spite of some reports describing this fish as having a very specialized life style. It aestivates during the dry season, and has developed metabolic adaptations to cope with both flooding and drought. The literature describing its tissue ultra-structure shows high ...

Transportation of juvenile tambaqui (Colossoma macropomum) in a closed system
Gomes, Levy de Carvalho; Araújo-Lima, Carlos Alberto Rego Monteiro; Chippari-Gomes, Adriana Regina; Roubach, RodrigoThe objective of this study was to investigate the effect of density, duration and the use of additives to the water during the transportation of juvenile tambaqui (Colossoma macropomum) and use of this data to establish a safe transportation protocol for the species. The tested products and dosages were: salt (1000, 2000 and 3000 mg/L), gypsum (100, 300 and 500 mg/L) and benzocaine (10, 20 and 30 mg/L). Fish w...
