Life‐History and Landscape Context Shaping the Spatial Genetic Structure of the Migratory Amazonian Fish Prochilodus nigricans

Freshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT The Neotropical migratory fish Prochilodus nigricans plays a critical ecological and socioeconomic role in the Amazon basin. Nevertheless, little is known about its populations and the genetic diversity pattern of the species. In light of this, the current study investigates the spatial genetic structure and diversity of P.

Integrating curimba culture during the grow‐out phase of tambaqui affects overall productivity, water quality, and fish health

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract The efficiency of feed use in aquaculture may be improved by integrating the culture of extractive species into fed‐species systems. This study assessed the impact of including curimba (Prochilodus lineatus) in tambaqui (Colossoma macropomum) production during the grow‐out phase in earthen ponds.

Low genetic variability in Prochilodus lacustris and Prochilodus nigricans from river basins of northern and northeastern Brazil

Boletim do Instituto de Pesca
The genus Prochilodus is an important fish resource. The various species within this genus are morphologically very similar, making reliable taxonomic identification difficult and creating uncertainty regarding the exact status of the different forms ...

New cases of supernumerary chromosomes in characiform fishes

Genetics and Molecular Biology, 1999
Supernumerary chromosomes were described for five species of Neotropical characiform fishes. These extra chromosomes were small, acrocentric and fully heterochromatic in Leporinus friderici from two different localities as well as in Leporinus sp., but ...

Ossification of the cranium of Inpaichthys kerri (Characiformes: Acestrorhamphidae) with discussion of paedomorphic traits in the genus

Journal of Anatomy, Volume 248, Issue 5, Page 806-829, May 2026.
In this study, we present a detailed description of the cranial development of Inpaichthys kerri (Characiformes: Acestrorhamphidae), highlighting important topics such as pedomorphic characters and their relationship with ontogeny and phylogeny, as well as ossification sequences unique to the species. Abstract The study of development provides valuable

Fertilizing Capacity of the Cryopreserved Sperm of Prochilodus brevis

Acta Scientiae Veterinariae, 2019
Background: Seminal cryopreservation is a technique that optimizes aquacultural production, as it requires less breeding and enables reproduction outside of the breeding season. This technique also helps to preserve species, thus reducing the pressure on the natural stocks.
