ABSTRACT. The piava (Leporinus obtusidens) is a migratory freshwater fish. There is relatively little information on the hematological and morphological.

Distinct pairs breed on densely grown weedy places Ref. Pignalberi de Hassan Cordiviola de Yuan, E. 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.

In this study, teleostean fish Leporinus obtusidens piava were exposed to different concentrations of Roundup, a glyphosate acid equivalent herbicide: Megaleporinus obtusidens is an omnivore: 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.
Dorsal soft rays total: The back, as usual in this habitat, is darker than the belly.
Medium, minimum population doubling time 1. It prefers warm waters and reproduces in spring and summer, starting at 2 years of age. Freshwater; benthopelagic; potamodromous Ref. Differs from a similar species Leporinus piavussu by having 41 to 43, rarely 44 perforated obtuidens in the lateral line vs.
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.
The common name boga is applied to many other species of fish, usually unrelated to this one. There is also a variant called piava and another called tres puntos “three dots”.

Downloaded on keporinus July 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. Levels of ammonia in both tissues increase in fish at all glyphosate concentrations.
Differs from Leporinus amblyrhynchusL. This species is also known by the technical synonym Curimatus obtusidens. This page was last edited on 22 Marchat Metabolic parameters in the liver and muscle lactate, glycogen, glucose, protein, and ammoniaas well as some hematological parameters, were determined.
Estimates of some properties based on models Phylogenetic diversity index Ref. Retrieved from ” https: Lbtusidens AChE activity was verified in brain and muscle tissues. Its basic colour is a light greenish-gray, with three rounded dark spots in mid-flank, which may not be visible in some specimens.
