Avaliação da relevância de Salminus hilarii Valenciennes, 1850 como bioindicador utilizando cienciometria

open access: yesActapesca
The use of indexed databases has proven to be a robust and relevant tool in assessing the importance of Salminus hilarii for histopathology and hematology studies. This study sought to reveal the potential of this species as a bioindicator in the context of the Rio dos Bois basin, in northwestern Goiás, Brazil.

Optimizing a metabarcoding marker portfolio for species detection from complex mixtures of globally diverse fishes

open access: yesEnvironmental DNA, Volume 5, Issue 6, Page 1589-1607, November 2023., 2023
We assessed the performance of 22 DNA metabarcoding primer sets for detecting 103 species of marine and freshwater bony fishes, elasmobranchs, cephalopods, and crustaceans. We find that a portfolio of four markers targeting 12S, 16S, and multiple regions of COI identifies all reference taxa to family and nearly 60% to species.

Spawning induction and embryonic development of Salminus hilarii (Characiformes: Characidae)

open access: yesZygote, 2020
SummaryThe present study aimed to evaluate two different methods of artificial reproduction induction, and characterize the embryonic development of Salminus hilarii. Different than observed for other tropical fish species, artificial reproduction induction followed by hand-stripping of gametes was considered unfeasible for S.
