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.

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.

Energy Compartmentalization in a Migratory Fish, Prochilodus mariae (Prochilodontidae), of the Orinoco River

Copeia, 1983
Energy compartmentalization in migrating and nonmigratingProchilodus mariae was monitored throughout the season of gonad maturation. Both migrating and nonmigrating individuals matured sexually. Rates of maturation were similar for migrating and nonmigrating individuals of both sexes. The overall caloric density of P.

Neoechinorhynchus curemai (Acanthocephala: Neoechinorhynchidae) in Prochilodus lineatus (Osteichthyes: Prochilodontidae) from the Paraná River, Brazil

Veterinary Parasitology, 2005
This work evaluated parasitic infections by Neoechinorhynchus curemai (Acanthocephala: Neoechinorhynchidae) in Prochilodus lineatus captured between August 2000 and August 2001 in the Paraná River, Presidente Epitácio, São Paulo, Brazil. Of 87 fishes examined, 59 were infected (25 males and 34 females). High mean intensities occurred in August 2000 (45.

Cryoprotective effect of egg yolk in semen of Prochilodus mariae (Characiformes: Prochilodontidae)

2020
Prochilodus mariae é uma espécie endêmica do rio Orinoco, de grande importância ecológica, cultural e econômica, cujo protocolo de criopreservação seminal ainda não foi estabelecido. O objetivo deste trabalho foi avaliar o efeito do uso e exclusão da gema de ovo no diluente de criopreservação, na qualidade seminal de P. mariae.

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).

Evidence of isolation by time in freshwater migratory fish Prochilodus costatus (Characiformes, Prochilodontidae)

Hydrobiologia, 2015
The coexistence of individuals in the same river and their ability to make long-distance migrations suggest that they constitute a single panmictic population; however, several studies have indicated population genetic structuring in freshwater migratory fish species.

NOVA METODOLOGIA DE HIPOFISECTOMIA EM CURIMATÃ Prochilodus brevis (PISCES, PROCHILODONTIDAE)

Revista Brasileira de Engenharia de Pesca, 2009
No nordeste de Brasil, peixes reofilicos total são usados como doadores de hipófises. O presente trabalho descreve uma nova metodologia de hipofisectomia em curimatãs, Prochilodus brevis desenvolvida na Estação de Piscicultura de Paulo Afonso EPPA), da Companhia Hidro Elétrica de São Francisco (CHESF) buscando melhor utilização do peixe ...
