Replacement of Fish Meal With Poultry Viscera Meal in Diets for Juvenile Arapaima gigas: Growth Performance, Hematological Parameters, Fillet Composition, and Gut and Liver Histology

Aquaculture Research, Volume 2026, Issue 1, 2026.
This study aimed to evaluate the effects of replacing fish meal with poultry viscera meal (PVM) in diets for juvenile Arapaima gigas, assessing growth performance, hematological parameters, fillet composition, and gut and liver histology. Five isonitrogenous (450.20 g kg−1 crude protein [PRO]) and isocaloric (20.02 MJ kg−1 gross energy) diets were ...

Chemical composition of different muscle zones in pirarucu (Arapaima gigas) [PDF]

Food Science and Technology, 2017
Abstract Identifying potential patterns in pirarucu ( Arapaima gigas ) composition, as a function of the different fish muscle zones (dorse, venter, ventrecha and tail), was the main objective of this research. For such, the different pirarucu muscle zones were evaluated, in order to obtain proximate composition and minerals content.

Co‐Supplementation of Vitamins C and E Ameliorates Growth, Blood Biochemistry, Histomorphometry and Mucosal Health in Nile Tilapia, Oreochromis niloticus Under High Stocking Density

Aquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT Supplementing diets with vitamins C and E has been reported to reduce the negative effects of stress associated with higher stocking density. This study investigated the combined effects of dietary vitamins C and E on the growth, nutritional composition, haematobiochemical response and mucosal health of Nile tilapia, Oreochromis niloticus ...

Morphology and expression of genes related to skeletal muscle growth in juveniles of pirarucu (Arapaima gigas, Arapaimatidae, Teleostei) - doi: 10.4025/actascianimsci.v35i3.18219

Acta Scientiarum: Animal Sciences, 2013
Skeletal muscle growth in the pirarucu (Arapaima gigas) is highly interesting to fish farmers because it provides information about how the mechanism in muscle mass increase, characteristic of the species, is regulated.

Amazonian fish migration as a social–cultural–ecological process

People and Nature, Volume 7, Issue 12, Page 3297-3312, December 2025.
Abstract In this study, we highlight the rich perspectives and explanations of fish migration held by Indigenous groups across the Amazon. We present the aspects of Indigenous cosmological stories, drawing from our exploratory review of cultural ethnographies and grey literature, as well as the authors' own experiences. We ask, how do Amazonian peoples

Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Conservation strategies for Arapaima gigas (Schinz, 1822) and the Amazonian várzea ecosystem

Brazilian Journal of Biology
In the present study we report a spatial autocorrelation analysis of molecular data obtained for Arapaima gigas, and the implication of this study for conservation and management. Arapaima is an important, but critically over-exploited giant food fish of

Seasonal Forest Resources Support Fish Biomass in Floodplain Lakes of an Amazonian Tributary

Freshwater Biology, Volume 70, Issue 11, November 2025.
ABSTRACT The Flood Pulse Concept is a foundational ecological theory that emphasizes the critical role of lateral connectivity between a river channel and its floodplain. Many tropical rivers inundate the surrounding floodplain in the flood stage, thereby receiving large amounts of terrestrial organic matter that can be decomposed by microbes and ...
