Induced breeding of the sabalo, Prochilodus platensis Holmberg

Aquaculture, 1984
Abstract Maturation and ovulation were induced in female Prochilodus platensis with multiple homologous pituitary extract injections (total dose 0.9 to 1.4 hypophysis/kg) or single injections of pituitary extract combined with human chorionic gonadotrophin ((1 hypophysis + 500 I.U.)/kg). One of the females given the latter treatment produced viable

Interaction of non-ionic surfactants with hepatic CYP in Prochilodus scrofa

Toxicology in Vitro, 2004
Cytochromes P450 (CYP) constitute a superfamily of hemeproteins that play a vital role in the metabolism of a wide variety of endogenous and xenobiotic compounds. Xenobiotic metabolism and the role of CYP are of particular interest in studies regarding the prevention of the damage caused by chemical pollutants.

Biomarkers of waterborne copper exposure in the Neotropical fish Prochilodus lineatus

Aquatic Toxicology, 2016
The main goal of the present study was to investigate the effects of acute exposure to copper (Cu) using a Neotropical freshwater fish as sentinel species through multi biomarkers analysis at different biological levels. Juveniles of Prochilodus lineatus were kept under control condition (no Cu addition in the water) or exposed to environmentally ...

Histology, histochemistry and stereology of the adipose fin of Prochilodus lineatus

Microscopy Research and Technique, 2011
AbstractThe adipose fin is small, nonpared, and usually located medially between the dorsal and caudal fin. Its taxonomic occurrence is very restrict; thus, it represents an important trace for taxon distinction. As it does not play a known vital physiological roll and it is easily removed, it is commonly used in marking and recapture studies.

B-chromosome frequency stability in Prochilodus lineatus (Characiformes, Prochilodontidae)

Genetica, 2009
The 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.

Lead accumulation and its effects on the branchial physiology of Prochilodus lineatus

Fish Physiology and Biochemistry, 2013
The purpose of this work was to determine the tissue accumulation of lead (Pb) and its effects on osmoregulatory processes of the freshwater fish Prochilodus lineatus. Juvenile fish were exposed to Pb (from 1.7 to 0.7 mg of dissolved Pb L(-1)) for 6, 24 and 96 h and Pb accumulation was analyzed in the gills, liver, kidneys, blood cells and muscle.

Storage and transportation of Prochilodus lineatus (Characiformes) sperm prior to cryopreservation

General and Comparative Endocrinology, 2017
In this study we compared post-thaw quality of P. lineatus sperm frozen shortly after collection, with sperm frozen after dilution and transportation, and up to 6h from collection. From each sperm sample (n=10 males) five aliquots were taken. One aliquot was diluted in the freezing medium (1 sperm:8 glucose:1 methyl glycol) and frozen ∼20min after ...

Genotoxic Effects of Aluminum on the Neotropical Fish Prochilodus lineatus

Water, Air, & Soil Pollution, 2010
Applying an integrated approach using the Comet, micronucleus (MN), and random amplified polymorphic DNA (RAPD) assays, occurrence of erythrocytic nuclear abnormalities (ENAs) and the liver activity of antioxidants enzymes (catalase and glutathione-S-transferase (GST)) was carried out to evaluate the effects of acute (6, 24, and 96 h) and subchronic ...

MORTALIDADE NO TRANSPORTE DE CURIMATÃ-PACU (Prochilodus argentus)

Revista Brasileira de Engenharia de Pesca, 2009
A mortalidade de juvenis após transporte é um dos principais entraves para seu cultivo do curimatã-pacu. Este trabalho teve como objetivo testar o transporte de juvenis de curimatã-pacu com adição de produtos redutores de estresse. Os produtos testados foram: cloreto de sódio (2,0g/L), gesso 0,5g/L, óleo de cravo 0,02ml/L, mais o tratamento ...

Study of the embrionary development in sábalo (Prochilodus lineatus)

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