Predation on pirarucu larvae by opportunistic fish species

Acta Amazonica, 2022
One of the constraints in pirarucu, Arapaima gigas farming is the reproduction in captivity, due to inconsistent number of spawning events per reproductive cycle, thus, unreliable availability of juvenile fish. This is a first-hand report on predation of

Ammonia Increases the Stress of the Amazonian Giant Arapaima gigas in a Climate Change Scenario [PDF]

Animals, 2023
Ammonia is toxic to fish, and when associated with global warming, it can cause losses in aquaculture. In this study, we investigated the physiological and zootechnical responses of Arapaima gigas to the current scenarios and to RCP8.5, a scenario ...

Effects of Dietary Lipid Levels on Growth Performance, Hematological Parameters, and Muscle Fatty Acid Composition of Juvenile Arapaima gigas [PDF]

Animals
This study evaluates the effects of dietary lipid levels on growth performance, hematological health, and muscle composition of juvenile Arapaima gigas. We tested five isonitrogenous diets (451.7 g kg−1 of crude protein) with increasing lipid levels (6%,

Synthesis of Arapaima gigas Growth Hormone (ag-GH) in HEK 293 Cells: Its Purification and Characterization via In Vivo Bioassay in Dwarf “Little” Mice [PDF]

Molecules
Arapaima gigas growth hormone (ag-GH) cDNA was previously cloned from A. gigas pituitaries. In this work ag-GH has been synthesized using human embryonic kidney 293 cells (HEK293) transiently transfected with the 3.4-TOPO® vector carrying ag-GH cDNA. The

Combined osmotic dehydration and drying process of pirarucu (Arapaima gigas) fillets. [PDF]

J Food Sci Technol, 2017
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.

Anestesia do pirarucu por aspersão da benzocaína diretamente nas brânquias Anesthesia in pirarucu by benzocaine sprays in the gills

Ciência Rural, 2010
O pirarucu (Arapaima gigas) é um peixe que pode atingir mais de 2m e 100kg. No entanto, por ser um animal de grande porte, o risco de acidentes é bastante elevado durante o manejo. Logo, anestésicos são essenciais para segurança no trabalho.
