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

open access: yesJournal of Fish Biology, EarlyView.
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.

Molecular phylogeny reveals a new species of ghost electric knifefish Porotergus Ellis 1912 (Gymnotiformes: Apteronotidae), from the Amazon basin

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of ghost electric knifefish, Porotergus sambaibensis sp. nov., is described from the Javaés River, a tributary of the Araguaia River in Brazil. The new species was assigned to the genus Porotergus as the closest relative to Porotergus gimbeli through maximum likelihood reconstruction of a concatenated multilocus dataset ...

Molecular characterization of Serrasalmidae hybrid in the upper Paraná River floodplain using molecular markers

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study reports the molecular identification of a tambacu—a hybrid of Colossoma macropomum and Piaractus mesopotamicus—in the floodplain of the upper Paraná River using molecular markers. The PCR‐GEL method, based on the analysis of COI and TROP fragments, successfully characterized the hybrid, while PCR‐SEQ, employing RAG2 and TROP markers,

Contribution of Amino Acids in Cereal Grain Products to Precision Feed Formulation for Tambaqui (Colossoma macropomum) Using a Digestibility Approach

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Although cereal grain products have low protein content, they can contribute up to 25% of total protein in low‐trophic level/omnivorous fish diets. Thus, understanding the amino acid contribution of these ingredients becomes crucial for meeting the dietary requirements of omnivorous fish.
