Exposure to sublethal concentrations of Zn(II) and Cu(II) changes biochemical parameters in Leporinus obtusidens

Chemosphere, 2007
The aim of the present study was to assess the effect of the exposure of Leporinus obtusidens (Piava) to zinc and copper on catalase activity in the liver, delta-aminolevulinate dehidratase (delta-ALA-D) activity in liver, muscle, brain and kidney, and thiobarbituric reactive species (TBARS) in brain, muscle and liver.

Toxicological evaluation of landfill leachate using plant (Allium cepa) and fish (Leporinus obtusidens) bioassays

Waste Management & Research: The Journal for a Sustainable Circular Economy, 2013
The disposal of municipal waste in landfills may pose an environmental problem because the product of the decomposition of these residues generates large volumes of leachate, which may present high toxicity. The aim of this study was to assess the toxic and genotoxic effects of a sample of untreated leachate in fish ( Leporinus obtusidens) and onions (

Effects of four rice herbicides on some metabolic and toxicology parameters of teleost fish (Leporinus obtusidens)

Chemosphere, 2007
Effects of different herbicides on acetylcholinesterase (AChE), catalase and TBARS formation in teleost fish (Leporinus obtusidens) were studied. Fish were exposed during 30 days at concentrations of herbicides used in rice field. AChE activity in the brain decreased significantly after exposure to the herbicides clomazone and quinclorac. However, AChE

Herbicide Formulation with Glyphosate Affects Growth, Acetylcholinesterase Activity, and Metabolic and Hematological Parameters in Piava (Leporinus obtusidens)

Archives of Environmental Contamination and Toxicology, 2010
The teleost fish Leporinus obtusidens (piava) was exposed to different concentrations of Roundup, a commercial herbicide formulation containing glyphosate (0, 1, or 5 mg L(-1)), for 90 days. Acetylcholinesterase (AChE) activity was verified in brain and muscle.

Gene banking of the neotropical fish Leporinus obtusidens (Valenciennes, 1836): A protocol to freeze its sperm in the field

Animal Reproduction Science, 2008
A practical sperm cryopreservation protocol using a dry-shipper and a diluent of simple composition is described for the neotropical fish Leporinus obtusidens (Valenciennes, 1836). The cooling rate of the dry-shipper and its period of useful time, established under laboratory conditions, were respectively 25.7-30.8 degrees C/min (between 0 and -60 ...

Toxicological and metabolic parameters of the teleost fish (Leporinus obtusidens) in response to commercial herbicides containing clomazone and propanil

Pesticide Biochemistry and Physiology, 2009
Pesticides, such as herbicides can affect the metabolic and toxicological parameters on fish. For this reason, an experiment was carried out with the objective of to evaluate the effects of commercial formulations of clomazone and propanil herbicides on acetylcholinesterase (AChE), thiobarbituric acid-reactive substances (TBARS), catalase (CAT) and ...

Morphology and 18S rDNA sequencing identifies Henneguya visibilis n. sp., a parasite of Leporinus obtusidens from Mogi Guaçu River, Brazil

Parasitology Research, 2013
During a survey of myxozoan parasites of freshwater fish from the Mogi Guaçu River in São Paulo State, Brazil, plasmodia of Henneguya visibilis n. sp. were found on the fins of Leporinus obtusidens (Characiformes: Anostomidae). The plasmodia, which were observed on five out of eight (62.5%) L. obtusidens examined, were 400-1,000 μm long.
