Combined osmotic dehydration and drying process of pirarucu (Arapaima gigas) fillets. [PDF]
The osmotic dehydration (OD) and complementary drying of pirarucu (Arapaima gigas) fillets were studied. Pieces of the dorsal portion of pirarucu (60 mm × 20 mm × 10 mm) underwent OD in a binary solution (NaCl-water) with the application of vacuum pulse following a central rotatable composite design.

Abstract The aim of the present study was to assess the use of sodium chloride (NaCl) against monogenoid infestations in pirarucu (Arapaima gigas). Two assays were conducted with pirarucu juveniles, the first comprising an in vitro exposure to 8; 9; 10 and 11 g.L− 1 NaCl and comparison to controls not exposed to NaCl, and the second, an in vivo

Heart structure in the Amazonian teleost Arapaima gigas (Osteoglossiformes, Arapaimidae) [PDF]
AbstractThe fish heart ventricle has varied morphology and may have a specific morpho‐functional design in species adapted to extreme environmental conditions. In general, the Amazonian ichthyofauna undergoes constant variations in water temperature, pH and oxygen saturation, which makes these species useful for investigations of cardiac morphology ...
