Long-term monitoring reveals a consistent female-biased sex ratio in Pimelodus maculatus from the Upper Uruguay River Basin

Boletim do Instituto de Pesca, 2023
Sex ratio is a crucial demographic parameter for the viability of natural populations, and it is commonly balanced in Neotropical freshwater fish species.

DNA metabarcoding of mock communities highlights potential biases when assessing Neotropical fish diversity

Environmental DNA, Volume 5, Issue 6, Page 1351-1361, November 2023., 2023
The performance of a taxonomy‐free approach using ASV/MOTUs was not as precise as assigning DNA reads to species using a curated 12S library that includes approximately 100 fish species since more than one ASV/MOTU was observed for the same specimen.

Fisheries in a border area of the Moxos Lowlands (Bolivia) after invasion of Arapaima gigas

Aquaculture, Fish and Fisheries, Volume 3, Issue 2, Page 196-210, April 2023., 2023
We characterized fisheries in the area of the port city of Riberalta (upper Madeira River basin) and evaluated the contribution of an invasive species (Arapaima gigas) to the landings. A. gigas represented 57.6% of the overall economic value of fish in the region.

Mini DNA barcodes reveal the details of the foraging ecology of the largehead hairtail, Trichiurus lepturus (Scombriformes: Trichiuridae), from São Paulo, Brazil

Neotropical Ichthyology, 2022
The largehead hairtail, Trichiurus lepturus, is an opportunistic, voracious, and piscivorous predator. Studies of fish feeding behavior based on the analysis of stomach contents are limited by the potential for the visual identification of the ingesta ...

Localization of ribosomal genes in three Pimelodus species (Siluriformes, Pimelodidae) of the São Francisco River: 5S genes as species markers and conservation of the 18S rDNA sites [PDF]

, 2008
Pimelodidae is one of the most representative of Neotropical catfish families. However, these fish are still poorly studied in terms of cytogenetics, especially regarding the application of more accurate techniques such as the chromosomal localization of
