Dietary Probiotics Improve Growth, Immunity and Disease Resistance in Fish Against Aeromonas hydrophila Infection

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Probiotics offer a promising alternative to antibiotics for managing Aeromonas hydrophila infections in aquaculture. Dietary supplementation of probiotics increases fish health, growth performance, and immune responses, while reducing antibiotic reliance in fish farming.

First Records of Length–Weight Relationships for Ten Fish Species From the Middle Stretch of the Uruguay River, Southern Brazil

open access: yesJournal of Applied Ichthyology, Volume 2026, Issue 1, 2026.
This study estimated the length–weight relationships (LWRs) of 10 fish species from the middle stretch of the Middle Uruguay River basin, aiming to provide new morphometric data and contribute to the knowledge of Neotropical ichthyofauna. Fish were collected at seven sites with sampling conducted at each site during every season, totaling 84 sampling ...

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 ...

Expansion of fluvial transport of commodities through the Pantanal floodplains of Brazil: Potential impacts and interference by climate change

open access: yesConservation Science and Practice, Volume 7, Issue 7, July 2025.
Abstract Inland waterways have historically been viewed as a desirable means for transporting commodities. However, creating and maintaining navigable river channels can entail substantial geomorphological modifications, resulting in changes to the ecohydrology of a river and its adjacent floodplains.

Ten relevant questions for applying biodiversity offsetting in the Pantanal wetland

open access: yesConservation Science and Practice, Volume 7, Issue 7, July 2025.
Here, we formulated 10 questions that discuss and illustrate how offsetting can be applied to maintain wetland integrity, economic fairness, and biodiversity conservation in the Pantanal and Upper Paraguay River basin (UPRB) We provided examples of offsetting implementation opportunities, analyze spatial compliance deficits, and illustrate requirements

Fish distribution across altitudinal gradients in the Upper Paraguay River Basin: Implications for conservation in the Pantanal region

open access: yesConservation Science and Practice, Volume 7, Issue 7, July 2025.
This paper approaches the patterns in fish distribution across the altitudinal gradient in the Upper Paraguay River basin, from uplands to the floodplain. We compiled more than 75,000 available fish records and registered 342 fish species and your distribution along altitudinal gradient. Floodplain portion have higher species diversity than headwaters,
