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.

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.

Thiacloprid Exposure Induces Oxidative Stress, Endoplasmic Reticulum Stress, and Apoptosis in the Liver of Mauremys reevesii. [PDF]

Ecol Evol
Thiacloprid (THI), widely used for crop protection and pest control, is easily residual and accumulated in the environment because of long half‐life and high leaching effect. The detectable rate of THI in soil and water is high, which can lead to the accumulation in organisms and cause toxic effects through sustained exposure to humans and nontargeted ...

B chromosome dynamics in Prochilodus costatus (Teleostei, Characiformes) and comparisons with supernumerary chromosome system in other Prochilodus species

Comparative Cytogenetics, 2017
Within the genus Prochilodus Agassiz, 1829, five species are known to carry B chromosomes, i.e. chromosomes beyond the usual diploid number that have been traditionally considered as accessory for the genome.

Cellular responses of Prochilodus lineatus hepatocytes after cylindrospermopsin exposure

Toxicology in Vitro, 2011
Cylindrospermopsin is a potent toxicant for eukaryotic cells produced by several cyanobacteria. Recently, primary hepatocyte cultures of Neotropical fish have been established, demonstrating to be a quite efficient in vitro model for cellular toxicology studies.

GENETIC IMPLICATIONS OF RESTOCKING PROGRAMS ON WILD POPULATIONS OF STREAKED PROCHILOD Prochilodus lineatus

Boletim do Instituto de Pesca, 2019
Genetic diversity of wild and farmed populations is crucial, both for conservation of fish resources and fish culture development. To infer the genetic diversity and population structure of Streaked prochilod Prochilodus lineatus, individuals were ...

Synapsis in supernumerary chromosomes of Prochilodus lineatus (Teleostei: Prochilodontidae) [PDF]

Caryologia, 1998
Summary Meiotic analysis performed on a sample of 10 specimens of Prochilodus lineatus revealed continuous filaments of different sizes stained by AgNO3, corresponding to the bivalent of the normal complement. Small supernumerary chromosomes were observed as isolated and well stained bodies, scattered among the other elements.
