The influence of sex ratio on the reproduction of pirarucu, Arapaima gigas, in captivity [PDF]

open access: diamondActa Amazonica, 2018
Because sex ratio in the broodstock can influence the reproductive behaviour of a species, the influence of sex ratio on the reproductive success of pirarucu, Arapaima gigas, in captivity was assessed.

Predation on pirarucu larvae by opportunistic fish species

open access: yesActa 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]

open access: yesAnimals, 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 ...

Morphology and Histology of the Pirarucu (Arapaima gigas) Digestive Tract [PDF]

open access: diamondInternational Journal of Morphology, 2017
The present study describes the morphology and histology of the digestive tract of juvenile pirarucu, which is a Neotropical fish species with great potential for aquaculture in the Amazon region. Three size classes of pirarucu juveniles from commercial fish farms were sampled for histological examination of the oesophagus, stomach, pyloric caeca ...
