Response of Prochilodus nigricans to flood pulse variation in the central Amazon [PDF]

Royal Society Open Science, 2018
The influence of the flood pulse on fish populations has been posited, but infrequently tested or quantified. Here, we tested the effect of habitat on population size, using Prochilodus nigricans as a case study species. Floodplain habitat was based on the littoral zone area occupied by P. nigricans

Genetic Structure and Conservation Strategies for the Endangered Catfish Steindachneridion melanodermatum (Siluriformes, Pimelodidae) in the Iguaçu River, Brazil

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.
ABSTRACT The endemic catfish Steindachneridion melanodermatum from the Iguaçu River basin, southern Brazil, is one of the most threatened pimelodid species. Comprehension of its genetic structure is imperative to the formulation of long‐term efficacious conservation strategies. A genetic analysis was conducted on three populations from the lower Iguaçu

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.

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 ...

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.

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.
