Ichthyofauna Used in Traditional Medicine in Brazil

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2012, Issue 1, 2012., 2012
Fish represent the group of vertebrates with the largest number of species and the largest geographic distribution; they are also used in different ways by modern civilizations. The goal of this study was to compile the current knowledge on the use of ichthyofauna in zootherapeutic practices in Brazil, including ecological and conservational commentary

A new endemic pearl cichlid of the ‘Geophagus’ brasiliensis (Cichliformes: Cichlidae) species group from the Piranga River, upper Doce River basin, southeastern Brazil

open access: yesJournal of Fish Biology, Volume 108, Issue 6, Page 1687-1700, June 2026.
Abstract A new species of pearl cichlid of the ‘Geophagus’ brasiliensis species group, endemic to the Piranga River, a major tributary of the upper Doce River basin in the state of Minas Gerais, southeastern Brazil, is herein described. The new species is delimited using an integrative approach, with molecular‐based species delimitation methods coupled

Management Strategies and Agricultural Calendars for Forage Production in Semi‐Arid Brazil Using AquaCrop

open access: yesIrrigation and Drainage, Volume 75, Issue 1, Page 411-424, February 2026.
ABSTRACT Forage production in semi‐arid regions of Brazil is limited by water deficit. This study aimed to identify the most adapted and efficient production systems and define their agricultural calendars for the semi‐arid region of Brazil. Twenty‐nine production arrangements that included different cropping conditions, plant density, plant cycles ...

NON-STARCH POLYSACCHARIDE IN DIETS FOR HYBRID SURUBIM: EFFECTS ON METABOLISM PLASTICITY

open access: yesBoletim do Instituto de Pesca, 2019
This study aimed to analyze the effect of mango meal, a non-starch polysaccharide, as a carbohydrate source on the metabolism plasticity and performance indicators for hybrid surubim (Pseudoplatystoma fasciatum x P. corruscans), a tropical carnivorous fish. Juveniles (±14.5g initial weight) were fed 3% of total biomass for 60 days in four experimental

Low‐Effort eDNA Sampling Reveals Fish Community Patterns in a Neotropical River Basin

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
Low eDNA sampling effort (< 10 sample sites) using a portable on‐site kit with syringe filters and a modest water volume (< 500 mL per site) provided a rapid and robust snapshot of fish biodiversity. Environmental DNA based species richness increases along the upstream‐downstream gradient showing a significant negative correlation with river elevation ...

Structural Analysis of Embryonic Development of Embryos From the Crossing of Two Species of Siluriform

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
Based on the need for knowledge about the biology of hybrid fish specimens currently being produced by commercial fish farmers, this study aimed to study the initial ontogenesis up to the fifth day after larval hatching of the Hybrid LP produced by crossing Leiarius marmoratus (♀) and Pseudoplatystoma reticulatum (♂), thus producing important data for ...

Analysis of Migratory Catfish Production from Artisanal Fishing in the Middle Madeira Sub‐Basin Using New Monitoring Methods, Southwestern Amazon

open access: yesJournal of Applied Ichthyology, Volume 2024, Issue 1, 2024.
Studies on the production of Pimelodidae catfish in the Amazon are generally carried out in large fishing centers. However, the data referring to small‐scale fisheries have gaps that can represent a risk to the activity. This study evaluated the volume produced and the revenue obtained from migratory catfish of the Pimelodidae family of commercial ...
