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

Conservation 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,

Megalocytivirus: A Review of Epidemiology, Pathogenicity, Immune Evasion, and Prevention Strategies

Reviews in Aquaculture, Volume 17, Issue 3, June 2025.
ABSTRACT Megalocytivirus, a large double‐stranded DNA virus belonging to the Iridoviridae family, has infected over 100 species of fish, leading to significant economic losses in the aquaculture, food, and ornamental fish industries. These viruses exhibit icosahedral symmetry and have diameters ranging from 120 to 200 nm.

Experimental assessment of the effects of a Neotropical nocturnal piscivore on juvenile native and invasive fishes

Neotropical Ichthyology
We experimentally examined the predator-prey relationships between juvenile spotted sorubim Pseudoplastystoma corruscans and young-of-the-year invasive and native fish species of the Paraná River basin, Brazil. Three invasive (peacock bass Cichla piquiti,

Length‒Weight and Length‒Length Relationships of Freshwater Fish Species Caught by Professional Fishermen in the Itaipu Reservoir, Brazil

Journal of Applied Ichthyology, Volume 2025, Issue 1, 2025.
Length‒weight relationships (LWRs) and length‒length relationships (LLRs) were estimated for 63 and 58 freshwater fish species, respectively, captured in the Itaipu Reservoir, Paraná River Basin, Paraná State, Brazil. Sampling was carried out from March 1987 to July 2024 at 63 professional fishing sites within the reservoir’s area of influence ...

The economic displacement of thousands of fishers in the Pantanal, Brazil: A telling story of small‐scale fisheries marginalization worldwide.

Fish and Fisheries, Volume 25, Issue 6, Page 951-958, November 2024.
Abstract A new policy in the Pantanal wetland, Brazil, aims to economically displace thousands of artisanal fishers from one‐third of the region. The legislation disregards several FAO Voluntary Guidelines for Securing Sustainability in Small‐Scale Fisheries' guiding principles (SSF guidelines). Considering that 2024 marks the 10th anniversary of these
