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.

Genetic variability of Prochilodus lineatus (Characiformes, Prochilodontidae) in the upper Paraná river

Genetics and Molecular Biology, 1997
The genetic variability of the "curimba", Prochilodus lineatus, from three locations in the Paraná river basin, was investigated by starch gel electrophoresis. A total of 160 specimens were analyzed for 19 enzymes, 12 of which permitted successful interpretation of electrophoretic patterns.

Initial development of Prochilodus hartii (Pisces: Prochilodontidae) submitted to induced reproduction

Zygote, 2015
SummaryThe Prochilodontidae prepare for reproduction in captivity, but neither ovulation nor spawning occurs, thus requiring induced reproduction for breeding and restocking. This study analyzed for the first time the embryogenesis and larval ontogeny of P.

Distribution of economically important fish larvae (Characiformes, Prochilodontidae) in the Central Amazonia, Brazil

Fisheries Management and Ecology, 2017
AbstractThe spatio‐temporal patterns of three species of Prochilodontidae larvae that are intensely used as fishery resources in Central Amazonia are analysed. Sampling was conducted during 2011 at four stages of the hydrological cycle (flood, high water, falling and low water phases).

Downstream effects of a large reservoir on the reproductive activity of Prochilodus hartii (Pisces: Prochilodontidae)

Animal Reproduction Science, 2018
To analyze the effect of the Irapé reservoir on the reproduction of "curimba", Prochilodus hartii, a migratory species, 503 specimens were collected during the reproductive period from February 2012 to January 2013. Specimens were collected from two river sections within the Jequitinhonha River Basin: Site 1 - a section of the Itacambiruçu River, a ...

Intestinal histology of a detritivorous (iliophagous) fish Prochilodus scrofa (characiformes, prochilodontidae)

Annales des Sciences Naturelles - Zoologie et Biologie Animale, 1998
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 ...

Utilization of endogenous reserves and effects of starvation on the health of Prochilodus lineatus (Prochilodontidae)

Environmental Biology of Fishes, 2011
Prochilodus lineatus Valenciennes (curimbata) is an important migratory Neotropical fish. It does not feed during spawning migration, and often survives after spawning. The mobilization of energy reserves and some effects of starvation (zero to eight weeks) on fish health were experimentally evaluated.
