Genetic Structure and Conservation Strategies for the Endangered Catfish Steindachneridion melanodermatum (Siluriformes, Pimelodidae) in the Iguaçu River, Brazil

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.
ABSTRACT The endemic catfish Steindachneridion melanodermatum from the Iguaçu River basin, southern Brazil, is one of the most threatened pimelodid species. Comprehension of its genetic structure is imperative to the formulation of long‐term efficacious conservation strategies. A genetic analysis was conducted on three populations from the lower Iguaçu

Ichthyofauna Used in Traditional Medicine in Brazil

Evidence-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

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

Boletim 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

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

Irrigation 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 ...

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

Environmental 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

Aquaculture 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 ...
