Exposure to this herbicide produced a decrease in all hematological parameters tested. In young individuals there are also eight broad vertical streaks, joined in the back and coming down to the middle line.

Megaleporinus obtusidens has an elongated wide body, with a comparatively small head obtusiedns a blunt mouth; its teeth are reminiscent of the incisors of Lagomorphawhence the name of the genus leporinus” hare -like”, as in Leporidae. They also occur in ponds. Curimatus obthsidens Valenciennes, Leporinus silvestrii Boulenger, Leporinus aguapeiensis Amaral Campos, Leporinus obtusidens Valenciennes, In addition, fish exposed to all glyphosate concentrations showed a significant increase in hepatic glycogen and glucose, but a significant reduction in muscle glycogen and glucose.


It prefers warm waters and reproduces in spring and summer, starting at 2 years of age. High vulnerability 62 of Levels of ammonia in both tissues increase in fish at all glyphosate concentrations.

Megaleporinus obtusidens is an omnivore: Can be further distinguished from Leporinus muyscorum by having six or seven scale rows between lateral line and dorsal-fin origin vs.

Acetylcholinesterase AChE activity was verified in brain and muscle tissues. Cordiviola de Yuan, E.

Differs from Leporinus amblyrhynchusL. Lactate and protein of fish exposed to all glyphosate concentrations presented leporins significant decrease leporjnus the liver, but did not change significantly in the muscle.

The common name boga is applied to many other species of fish, usually unrelated to this one. Phylogenetic diversity index Ref. This page was last edited on 22 Marchat Can be diagnosed from most congeners, except Leporinus amblyrhynchusL.

There is also a variant called piava and another called tres puntos “three dots”. These results indicate that AChE activity as well as metabolic and hematological parameters may be good early indicators of herbicide contamination in L. Distinct pairs breed on densely grown weedy places Ref. Metabolic parameters in the liver and muscle lactate, glycogen, glucose, protein, and ammoniaas well as some hematological parameters, were determined.
