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]
AnimalsThis 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]
MoleculesArapaima 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

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

Feeding frequency affects feed intake and growth in juvenile pirarucu (Arapaima gigas) [PDF]
Acta Amazonica, 2019 Pirarucu is one of the main fish species for the development of aquaculture in the Amazon. In this study, the optimal feeding frequency for juvenile pirarucu was assessed based on growth and feed efficiency. Juvenile pirarucu weighing ca.

Oropharyngeal morphological aspects of Arapaima gigas (Schinz, 1822)
Boletim do Instituto de Pesca, 2022 The study of the functional anatomy of the digestive system of fish, in particular the oropharyngeal cavity, is of great importance because it allows inferences about the feeding habit, mechanisms of capture, selection, and processing of food carried ...
