Hybridization, Maternal Inheritance, and Evolutionary Time of Divergence of Endangered Species of <i>Hypancistrus</i> (Siluriformes: Loricariidae) in the Xingu River. [PDF]
We uncover recent hybridization dynamics among three endemic Hypancistrus species from the Xingu River, including the critically endangered H. zebra. Mitogenomic analyses reveal unidirectional maternal inheritance and recent evolutionary radiation (< 0.5 Ma), explaining their retained reproductive compatibility.

Spatial and temporal population genetic analysis of Semaprochilodus insignis (Prochilodontidae), an overexploited fish from the Amazon basin [PDF]
Background Semaprochilodus insignis is a migratory fish of commercial and subsistence importance to communities in the Amazon. Despite the high intensity of exploitation, recent studies have not been carried out to assess the genetic status of its stocks.

Scale morphology of Prochilodus lineatus with emphasis on the scale epithelium [PDF]
The fish body is entirely covered by a thin, smooth and glandular epidermis, closely attached to the scales inserted on the dermis. The descriptive work on this tissue dates to twenty or thirty years ago, bears very little photographic record and does not focus on the scale epithelium, despite the fact that it is in direct contact with the environment.

Use of Prochilodus lineatus meat for burger making [PDF]
Abstract The study aimed to elaborate burgers with fillet and pulp (fish carcass meat) of grumatã (Prochilodus lineatus), and to evaluate its centesimal composition, microbiological and sensorial properties. Three formulations were prepared. One was prepared with the fillet (0% pulp), and the remaining two contained 15% or 30% pulp (instead of fillet),

Atresia Folicular en Ovarios de Prochilodus lineatus [PDF]
Durante el periodo reproductivo, en el ovario de los teleosteos se forman ciclicamente foliculos primarios, los que maduran y son liberados en el momento de la ovulacion. Sin embargo, algunos de ellos desarrollan un proceso de atresia con degeneracion y reabsorcion, el que para ser considerado un evento fisiologico deberia predominar al final del ciclo
