Transcriptomic Divergence and Associated Markers Between Genomic Lineages of Silver Catfish (<i>Rhamdia quelen</i>). [PDF]

Ecol Evol
We present transcriptomic divergence between two latitudinally distributed lineages of Rhamdia quelen, which could explain local adaptations and the speciation processes proposed in previous studies. Moreover, the differentiation of transposable elements between lineages could also be associated with this speciation process.

Integrative morphometric and molecular analyses reveal possible genetic contamination of silver catfish populations of the genus Rhamdia in Neotropical River basins. [PDF]

J Fish Biol
Abstract Rhamdia quelen, Rhamdia branneri and Rhamdia voulezi are morphologically similar species that, until recently, were considered synonymous. Although R. quelen has wide distribution in the Neotropical region, R. branneri and R. voulezi are sympatric and endemic species of the Iguaçu River basin.

Celioscopic liver biopsy in silver catfish (Rhamdia quelen) [PDF]

Pesquisa Veterinária Brasileira, 2015
Endosurgery has been used for assessment of fish celomatic cavity, as well as for obtaining biopsies for organic analysis. Such minimally invasive access may also be used for the analysis of environmental impact on biomarkers of pollution. In Brazil, studies and literature regarding the use of celioscopy in fish are sparse.
