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.

Low‐Effort eDNA Sampling Reveals Fish Community Patterns in a Neotropical River Basin

Environmental 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 ...

Pimelodus microstoma Steindachner 1877

, 2018
Pimelodus microstoma. The diploid number was also 56 chromosomes (24 m + 18 sm + 8 st + 6 a) (Fig. 1d). The AgNORs were located in the terminal region of the long arm of a pair of subtelocentric chromosomes 24 (Fig. 1d, box). C-banding highlighted pale heterochromatin in the region of the centromere in the most of chromosomes, with more conspicuous ...

Efeito de fatores abióticos na larvicultura de pintado amarelo Pimelodus maculatus (Lacépède, 1803): salinidade e cor de tanque - DOI: 10.4025/actascianimsci.v26i2.1859

Acta Scientiarum: Animal Sciences, 2008
Fatores abióticos podem determinar o sucesso na larvicultura de algumas espécies de peixes. A cor do tanque e salinidade da água de criação podem promover alterações no comportamento e na fisiologia das pós-larvas de peixes.

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 ...

Relationship Between Marine Fish Production and Climatic and Oceanographic Factors: Evidence From the Bay of Bengal, Bangladesh

Aquaculture, Fish and Fisheries, Volume 5, Issue 2, April 2025.
ABSTRACT The fisheries sector is a cornerstone of Bangladesh's economy, contributing significantly to national gross domestic product (GDP) and export earnings. However, the production of other marine fish falls short of national expectations due to various reasons, such as overexploitation, destruction of habitat, pollution, climate change and ...

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 ...
