Zoologica Scripta, 2022 AbstractGeographically, widespread Neotropical fish lineages offer opportunities to reconstruct historical biogeography patterns and infer processes leading to modern ichthyological diversity and distribution. The characiform family Prochilodontidae is well suited for such reconstruction because their migrations limit population substructure within ...

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.

B-chromosome frequency stability in Prochilodus lineatus (Characiformes, Prochilodontidae)
Genetica, 2009The genus Prochilodus includes individuals ranging in size from medium to large, being highly relevant for commercial and subsistence fishing. Prochilodus species have a diploid number of 2n = 54 chromosomes and up to seven supernumerary (B) microchromosomes.

Complete mitochondrial genome sequence of Prochilodus lineatus (Characiformes, Prochilodontidae)
Mitochondrial DNA Part A, 2014Prochilodus lineatus (curimba) is an important Brazilian freshwater migratory fish with substantial economic importance in fishing. The complete mitochondrial genome of P. lineatus is 16,699 bp and contains 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes and one control region (D-loop). The mtDNA of P.

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.

Abstract The intestinal epithelium of Prochilodus scrofa, a freshwater teleost fish, was studied by means of light microscopic techniques. The samples were obtained from the initial, middle and terminal portions of each intestinal loop. The pyloric caeca are lined by a simple columnar epithelium with a small striated border and a very thick basal ...

Stable karyotypes: a general rule for the fish of the family Prochilodontidae?
Hydrobiologia, 2012Cytogenetic studies involving the family Prochilodontidae have shown that these fish can be characterized by a constant diploid number and a conserved karyotypic macrostructure. This study focused on comparative physical chromosomal mapping using 18S and 5S rDNA to compare the species Semaprochilodus insignis and S. taeniurus. Our results indicated the
