Manaus: a capital do tambaqui. [PDF]

, 2010
Até meados da década de 80, a piscicultura era atividade agropecuária pouco atrativa na Amazônia Ocidental devido à abundância de recursos pesqueiros na região. Mas com o crescimento acelerado dos centros urbanos do norte, em especial a cidade de Manaus,

Fine‐Scale Genomic Divergence in the Amazonian Pirarucu (Arapaima gigas) Highlights the Need for Local Management Strategies

Freshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Freshwater habitats face significant human disturbances globally, impacting food security and ecosystems. Protected areas can mitigate biodiversity loss, but limited data on population connectivity hinders conservation management. This study examines pirarucu (Arapaima gigas), a heavily exploited and threatened Amazonian fish, using genomic ...

Recomendações técnicas para a reprodução do tambaqui. [PDF]

, 2013
Das espécies nativas brasileiras, o tambaqui (Colossoma macropomum) é a mais produzida em cativeiro. Quase a totalidade da produção desse animal puro ocorre nos estados da região Norte do Brasil, com destaque para Rondônia.

The effect of fairy shrimp “branchoneta” (Dendrocephalus brasiliensis) as the initial diet of tambaqui postlarvae

Acta Scientiarum: Animal Sciences, 2021
The effect of fairy shrimp “branchoneta” as the first exogenous feed for tambaqui postlarvae was evaluated. A hundred and eighty larvae were distributed in 12 aquariums, containing 1.5L of water and the stocking density was 10 larvae per liter.

Digestible tryptophan requirement for tambaqui (Colossoma macropomum) fingerlings

REVISTA CIÊNCIA AGRONÔMICA, 2020
ABSTRACT The objective of this study was to determine the digestible tryptophan requirement of tambaqui (Colossoma macropomum) fingerlings and its relationship with digestible lysine. A total of 300 tambaqui fingerlings with three initial weights (2.12 ± 1.19, 8.13 ± 0.75, and 15.18 ± 1.91 g) were distributed in a randomized complete block design ...

Oxygen consumption from air and water, ammonia and urea‐N excretion, and Na+ fluxes during progressive aquatic hypoxia in Amazonian armoured catfish Pterygoplichthys gibbiceps and Pterygoplichthys pardalis

Journal of Fish Biology, Volume 108, Issue 3, Page 867-880, March 2026.
Abstract The Amazonian loricariid fish Pterygoplichthys gibbiceps, from the Rio Negro, and Pterygoplichthys pardalis, from the Rio Solimões, are facultative air‐breathers that can use the stomach as an air‐breathing organ. Measurement of oxygen uptake under progressive aquatic hypoxia revealed a relatively high hypoxia resistance of both species.

A eficácia do mentol como anestésico para tambaqui (Colossoma macropomum, Characiformes: Characidae) Efficacy of menthol as an anesthetic for tambaqui (Colossoma macropomum, Characiformes: Characidae)

Acta Amazonica, 2005
Os anestésicos são importantes na piscicultura para reduzir o estresse e a mortalidade no manejo. Este trabalho tem como objetivo determinar a eficácia do mentol para tambaqui durante o manejo.

Nitrogen excretion and oxygen consumption under severe hypoxia in siluriform fishes from the Amazon

Journal of Fish Biology, Volume 108, Issue 3, Page 881-893, March 2026.
Abstract Siluriform fishes collected from the Rio Negro and Rio Solimões proved to be highly resistant to aquatic hypoxia. In all four species analysed in this study, aquatic oxygen consumption significantly decreased from normoxic levels at water PO2 values near 1 kPa. Air‐breathing activity was observed only in Sturisoma sp. (Rio Negro).

Genetic variability of tambaqui broodstocks in the Brazilian state of Pará [PDF]

Revista Brasileira de Zootecnia, 2019
ABSTRACT The present study evaluated the genetic variability of the broodstocks of tambaqui hatcheries in the Brazilian state of Pará. Samples were obtained from the caudal fin of 110 broodstocks from one hatchery in each of four municipalities (Santarém, Peixe-Boi, Breu-Branco, and Ulianópolis), representing all the individuals of each hatchery stock.
