Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate

Transmission rate variation among three B chromosome variants in the fish Prochilodus lineatus (Characiformes, Prochilodontidae)

Anais da Academia Brasileira de Ciências, 2013
Cytogenetic studies were developed in Prochilodus lineatus (Valenciennes 1836), describing an interesting system of small supernumerary chromosomes. The purpose of this work is to study the frequency and morphology of B chromosomes in individuals from ...

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

Physiological effects of gasoline on the freshwater fish Prochilodus lineatus(Characiformes: Prochilodontidae) [PDF]

Neotropical Ichthyology, 2013
The purpose of this work was to evaluate the effects of the water-soluble fraction of gasoline (WSFG) on the Neotropical freshwater fish Prochilodus lineatus. The WSFG was prepared by mixing gasoline in water (1:4) and animals were exposed for 6, 24 and 96h to 5% diluted WSFG or only to water.

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.

Genetic variability of Prochilodus lineatus in artificial and semi-natural reproduction [PDF]

Italian Journal of Animal Science, 2017
Prochilodus lineatus is a South American fish of great economic and social importance that is impacted by high fishing pressure. Restocking programmes have tried to be effective in recovering natural populations; however, genetic and reproductive methodologies are necessary to make feasible the survival of released fingerlings.

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.
