Physiological responses to long fasting followed by refeeding in juveniles of pirapitinga, Piaractus brachypomus [PDF]

open access: yesActa Amazonica, 2023
For many fish species, prolonged fasting is part of their life cycle, as there are seasonal fluctuations in the quantity and quality of food available in their natural habitat.

Seasonality of reproduction of Piaractus brachypomus in South Bolivia

open access: yes, 2008
The reproductive period of Piaractus brachypomus is short in South Bolivia. This area is close to the Southern limit of the species and conditions favourable to its reproduction last for only a few months. In order to increase fry production, we studied the possibility of extending its spawning period in captivity.

Effect of dietary carbohydrates and lipids on growth in cachama (Piaractus brachypomus)

open access: yesAquaculture Research, 2012
The effects of diets with three contents of carbohydrates and lipids were evaluated on the growing performance of cachama Piaractus brachypomus juveniles (initial weight 7.8 ± 0.49 g). The experiments were performed a 3 × 3 factorial design (200, 280 and 360 g of carbohydrates and 40, 80 and 120 g of lipids kg−1).

Genetic identification of F1 and post-F1 serrasalmid juvenile hybrids in Brazilian aquaculture.

open access: yesPLoS ONE, 2014
Juvenile fish trade monitoring is an important task on Brazilian fish farms. However, the identification of juvenile fish through morphological analysis is not feasible, particularly between interspecific hybrids and pure species individuals, making the ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

The Flooding Gradient Affects Seed Dispersal by Fruit‐Eating Fishes in Amazonian Whitewater Floodplain Forests

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
This research approaches the interaction between frugivorous fish and the flooded forests in the central Amazon. We evaluated the fruit consumption by fish and the seed dispersal potential along the flood gradient. We tested the hypothesis that the role of fish as seed dispersers varies between low várzea (LV) and high várzea (HV) forests.

Production of cachama reciprocal hybrids in earth ponds [PDF]

open access: yesCiência Rural, 2019
: The growth of cachama hybrids, cachamoto (Colossoma macropomum ♀ x Piaractus brachypomus ♂) and cachamay (P. brachypomus ♀ x C. macropomum ♂) was compared for 154 days to determine which showed the better productivity.

Longitudinal Effects of Improved Pond Aquaculture Techniques on Household Well‐Being: A Case Study From Rural Bangladesh

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Improved pond management techniques (IPMTs) in rural Bangladesh increase household fish consumption and reduce poverty, yet their sustained adoption remains limited. Analysis of panel data demonstrates that practices such as sunlight exposure, liming, supplementary feeding, and fertilization yield significant improvements in household well‐being ...
