Factors determining the structure of fish assemblages in an Amazonian river near to oil and gas exploration areas in the Amazon basin (Brazil): establishing the baseline for environmental evaluation

Zoologia (Curitiba), 2015
Determining the significance of biotic and abiotic factors in the structuring of fish assemblages in freshwater environments is an important question in ecology, particularly in view of environmental changes caused by man.

Karyotype variability in neotropical catfishes of the family Pimelodidae (Teleostei: Siluriformes)

Neotropical Ichthyology
Karyotypic data are presented for four species of fish belonging to the Pimelodidae family. These species show a conserved diploid number, 2n = 56 chromosomes, with different karyotypic formulae.

Age and growth of the Duckbill Catfish (Sorubim cf. lima) in the Pantanal

Brazilian Journal of Biology
The Duckbill Catfish, Sorubim lima, is a predator of large South American rivers. The age and growth of S. lima were studied based on the pectoral fin-spines of samples collected from the Cuiabá River, Pantanal. The samples were taken from commercial and

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

Journal 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 ...

Evolutionary history of Middle American Rhamdia (Siluriformes: Heptapteridae) inferred from comparative mitogenomic data: Insights on historical biogeography and cave colonization in the group

Journal of Systematics and Evolution, Volume 63, Issue 6, Page 1501-1518, November 2025.
Investigating the systematics and biogeography of Neotropical catfishes of the genus Rhamdia refined phylogenetic hypotheses, including deep paraphyly of Rhamdia laticauda, supported northward dispersal catalyzed by emergence of the Panamanian Isthmus and imply that cave colonization is widespread, convergent, and recent, with established cave‐dwelling

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 ...

River Geomorphology and Fish Diversity Around the Manseriche Gorge, the Last Andean Crossing Is in Peril

Water Resources Research, Volume 60, Issue 11, November 2024.
Abstract The transition from the Andes to the Amazon lowland hosts a high biodiversity and currently is facing several anthropogenic activities, including hydropower infrastructure projects. Little is known about the geomorphology of the Andean gorges, rivers and the interaction with the fish diversity upstream and downstream of gorges.
