Distinct pairs breed on densely grown weedy places Ref. Its basic colour is a light greenish-gray, with three rounded dark spots in mid-flank, which may not be visible in some specimens. Megaleporinus obtusidens is an omnivore: In young individuals there are also eight broad vertical streaks, joined in the back and coming down to the middle line. Estimates of some properties based on models Phylogenetic diversity index Ref.
Megaleporinus obtusidens Conservation status.
Levels of ammonia in both tissues increase in fish at all glyphosate concentrations. This species is also known by the technical synonym Curimatus obtusidens.
Differs from a similar species Leporinus piavussu by having 41 to 43, rarely 44 perforated scales in the lateral line vs. Summary page Point data Common obtsidens Photos. From Wikipedia, the free encyclopedia. Acetylcholinesterase AChE activity was verified in brain and muscle tissues. The length and weight of the individuals are extremely variable according to the area, probably influenced by different feeding habits, opportunities and exploitation, as well as local leporonus variants.
They also occur in ponds. The common name boga is applied to many other species of fish, usually unrelated to this one.
Megaleporinus obtusidens – Wikipedia
Short description Morphology Morphometrics Dorsal soft rays total: 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.
It prefers warm waters and reproduces in spring and summer, starting at 2 years of age. Sounds Ciguatera Speed Swim. 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.
Entered by Torres, Armi G. The larger fish probably belong to other species of Leporinus either L. Pignalberi de Hassan ibtusidens, Phylogenetic diversity index Ref.

It may be found in the main courses and streams, as well as in lakes and lagoons; it often shelters among stones and aquatic vegetation. These results indicate that AChE activity as well as metabolic and hematological parameters may be good early indicators of herbicide contamination in L.
Articles with ‘species’ microformats Articles with Spanish-language external links. High vulnerability 62 of There is also a variant called piava and another called tres puntos “three dots”.
In addition, fish exposed to all obtksidens concentrations showed a significant increase in hepatic glycogen and glucose, but a significant reduction in muscle glycogen and glucose. Megaleporinus leporinnus has an elongated wide body, with a comparatively small head and a blunt mouth; its teeth are reminiscent le;orinus the incisors of Lagomorphawhence the name of the genus leporinus” hare -like”, as in Leporidae.
Can be diagnosed from most congeners, except Leporinus amblyrhynchusL.
The back, as usual in this habitat, is darker than the belly. Exposure to leporinuw 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. Curimatus obtusidens Valenciennes, Leporinus silvestrii Boulenger, Leporinus aguapeiensis Amaral Campos, Leporinus obtusidens Valenciennes, Megaleporinus obtusidens Valenciennes In this study, teleostean fish Leporinus obtusidens piava were exposed to different concentrations of Roundup, a glyphosate acid equivalent herbicide: Medium, minimum population doubling time 1.
