Spatial variations in fish assemblage structure in a southeastern Brazilian reservoir

Brazilian Journal of Biology
We assessed the fish assemblage structure and composition of Nova Ponte Reservoir (Araguari River, Upper Paraná Basin, Brazil). We observed significant differences in abundance (p = 0.0003), richness (p = 0.0005) and diversity (p = 0.02) between ...

Illuminating the Dark: Using eDNA Metabarcoding to Study the Unique Ichthyofauna of the Furnas Formation Sinkholes

Environmental DNA, Volume 7, Issue 4, July–August 2025.
Using eDNA metabarcoding, we assessed fish diversity in isolated sinkholes in southern Brazil, uncovering signs of local extinction and species persistence. This approach offers a non‐invasive tool for biodiversity assessment and informs conservation efforts in unique karst environments.

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 influence of dam construction on a population of Leporinus obtusidens (Valenciennes, 1847) (Pisces, Anostomidae) in the Yacyretá Reservoir (Argentina)

Fisheries Research, 2005
Abstract A field study of age, growth and mortality of the “boga”, Leporinus obtusidens (Valenciennes, 1847) was carried out in the Yacyreta Reservoir, High Parana River, Argentina. We compared age-structure, length–weight relationships and condition factor coefficients in phases previous (1990–1994) and subsequent (1995–1998) to the reservoir ...
