Megaleporinus obtusidens Conservation status. Megaleporinus obtusidens has an elongated wide body, with a comparatively small head and a blunt mouth; its teeth are reminiscent of the incisors of Lagomorphawhence the name of the genus leporinus” hare -like”, as in Leporidae.

Summary page Point data Common names Photos. Obtusidenw common name boga is applied to many other species of fish, usually unrelated to this one. Its basic colour is a light greenish-gray, with three rounded dark spots in mid-flank, oobtusidens may not be visible in some specimens.

In this study, teleostean fish Leporinus obtusidens piava were exposed to different concentrations of Roundup, a glyphosate acid equivalent herbicide: Metabolic parameters in the liver and muscle lactate, glycogen, glucose, protein, and ammoniaas well as some hematological parameters, were determined.

Phylogenetic diversity index Ref. Acetylcholinesterase AChE activity was verified in brain and muscle obtusidenx. Can be diagnosed from most congeners, except Leporinus amblyrhynchusL.


Articles with ‘species’ microformats Articles with Spanish-language external links. Pignalberi de Hassan Views Read Edit View history. Lactate and protein of fish exposed to all glyphosate concentrations presented a significant decrease in the liver, but did not change significantly in the muscle.

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

Exposure to this herbicide produced a decrease in all hematological parameters tested. However, it prefers grain and seeds wheat and maizeand it often gathers in large banks near ports, where cargo ships drop grains into the water.

These results indicate that AChE activity as well as metabolic and hematological parameters may be good early indicators of herbicide contamination in L. This species is also known by the technical synonym Curimatus obtusidens. Estimates of some properties based on models Phylogenetic diversity index Ref. Results indicated that AChE activity significantly decreased in the brain of fish exposed to all glyphosate concentrations tested, but in the muscle this parameter was not altered.
