Trends in Medicinal Uses of Edible Wild Vertebrates in Brazil

Evidence-Based Complementary and Alternative Medicine, Volume 2017, Issue 1, 2017., 2017
The use of food medicines is a widespread practice worldwide. In Brazil, such use is often associated with wild animals, mostly focusing on vertebrate species. Here we assessed taxonomic and ecological trends in traditional uses of wild edible vertebrates in the country, through an extensive ethnobiological database analysis. Our results showed that at

A Revision of the Neotropical Orb‐Weaving Spider Genus Scoloderus (Araneae: Araneidae)

Psyche: A Journal of Entomology, Volume 102, Issue 1-2, Page 49-72, 1995., 1995
More than one‐fourth of the spiders examined for this revision were collected since the neotropical genus Scoloderus was revised in 1976. Thirteen names have been proposed for what appear to be five valid species (Scoloderus cordatus, S. gibber, S. nigriceps, S. tuberculifer, and S. ackerlyi).

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 ...

Practical Diets Formulated With Different Plant‐Based Energy Ingredients Modulate Nutrient Utilization and Gut Morphology in Tambaqui (Colossoma macropomum)

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Despite the increasing use of plant‐based energy ingredients in aquaculture, few studies have evaluated the digestibility of practical diets formulated with these ingredients in an integrated manner with the metabolic responses, intestinal health, and productive performance of fish. This limits the understanding of their nutritional effects. This study

Impacts of Hydroelectric Dams on Amazonian Fisheries: Assessing Functional Attributes in the Madeira River

River Research and Applications, Volume 41, Issue 7, Page 1493-1502, September 2025.
ABSTRACT The Madeira River is one of the main tributaries of the Amazon Basin, supporting over 1300 known fish species. Fisheries in this region play a critical role for riverine populations, serving as a primary source of income and sustenance. In 2011, the construction of the Jirau and Santo Antônio hydroelectric dams (HEDs) was completed along the ...

Effects of Stocking Densities on the Growth Performance and Physiology of Juvenile Piaractus brachypomus in Recirculating Aquaculture System

Fishes
The effects of different stocking densities on the growth and physiology of juvenile Piaractus brachypomus were evaluated in two experiments. Experiment I used juveniles weighing 1.5 ± 0.4 g at the following densities for 20 days: D0.68—0.68 kg/m3; D1.45—

Associations between morphometric variables and weight and yields carcass in PirapitingaPiaractus brachypomus

Aquaculture Research, 2019
The objective of this work was to evaluate the association between morphometric variables and carcass characteristics in Pirapitinga. We used a thousand specimens of Pirapitinga with an average weight of 1,200 g, which were stunned, slaughtered, weighed, measured, and processed for morphometric and processing yield analysis, to obtain weights, carcass ...
