Occurrence of long–distance migratory fish Prochilodus lineatus (Valenciennes, 1837) (Characiformes: Prochilodontidae) in the Mirim lagoon watershed, Uruguay-Brazil: Updating and Distribution

Instituto de Ecologia y Ciencias Ambientales, 2023
. Records of the long-distance migratory Prochilodus lineatus extend its distribution to the southernmost part of the Brazilian territory, in the Jaguarão river, and confirm the record for the Uruguaian territory of Mirim lagoon and Tacuarí river. Twenty-

Estudio del desarrollo embrionario del sábalo (Prochilodus lineatus) [PDF]

Archivos de medicina veterinaria, 2010
El almacenamiento de espermatozoides de peces por medio de la criopreservacion es muy utilizado hoy en dia. Si bien se sabe que el proceso de congelamiento/descongelamiento genera la fragmentacion del ADN del espermatozoide, no se conocen las consecuencias que esto tiene en el desarrollo embrionario.

Karyotypic conservatism in five species of Prochilodus (Characiformes, Prochilodontidae) disclosed by cytogenetic markers

Genetics and Molecular Biology, 2013
The family Prochilodontidae is considered a group with well conserved chromosomes characterized by their number, morphology and banding patterns. Thence, our study aimed at accomplishing a cytogenetic analysis with conventional methods (Giemsa staining ...

River Damming Impacts on Fish Habitat and Associated Conservation Measures

Reviews of Geophysics, Volume 61, Issue 4, December 2023., 2023
Abstract River damming has brought great benefits to flood mitigation, energy and food production, and will continue to play a significant role in global energy supply, particularly in Asia, Africa, and South America. However, dams have extensively altered global river dynamics, including riverine connectivity, hydrological, thermal, sediment and ...

No evidence that the widespread environmental contaminant caffeine alters energy balance or stress responses in fish

Ethology, Volume 129, Issue 12, Page 666-678, December 2023., 2023
No effects of environmentally relevant caffeine exposure on the metabolic rate, general activity, antipredator behaviour, foraging behaviour and morphology of mosquitofish. Overall, exposure to environmental levels of caffeine did not have any energetic consequences in these fish.

Optimizing a metabarcoding marker portfolio for species detection from complex mixtures of globally diverse fishes

Environmental DNA, Volume 5, Issue 6, Page 1589-1607, November 2023., 2023
We assessed the performance of 22 DNA metabarcoding primer sets for detecting 103 species of marine and freshwater bony fishes, elasmobranchs, cephalopods, and crustaceans. We find that a portfolio of four markers targeting 12S, 16S, and multiple regions of COI identifies all reference taxa to family and nearly 60% to species.

Microplastics and copper effects on the neotropical teleost Prochilodus lineatus: Is there any interaction?

Comparative biochemistry and physiology. Part A, Molecular & integrative physiology, 2020
Microplastics (MP) are emerging contaminants widely found in aquatic ecosystems. In addition to MP toxicity itself, there is increasing concern about the MP adsorption capacity and the interactive effects with other contaminants, such as copper.

Scale morphology of Prochilodus lineatus with emphasis on the scale epithelium [PDF]

Brazilian Journal of Biology, 2013
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.

Effects of melatonin supplementation on the quality of cryopreserved sperm in the neotropical fish Prochilodus lineatus.

Theriogenology, 2021
The cryopreservation process causes damage to sperm structures and supplementation of the cryoprotective medium is an alternative to reduce these damages.
