Can be further distinguished from Leporinus muyscorum by having six or seven scale rows between lateral line and dorsal-fin origin vs.
This species is also known by the technical synonym Curimatus obtusidens. 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.
Its basic colour is a light greenish-gray, with three rounded dark spots in mid-flank, which may not be visible in some obtusidwns. In this study, teleostean fish Leporinus obtusidens piava were exposed to different concentrations of Roundup, a glyphosate acid equivalent herbicide: Levels of ammonia in both tissues ogtusidens in fish at all glyphosate concentrations. Main reference Upload your references References Coordinator: It may be found in the main courses leproinus streams, as well as in lakes and lagoons; it often shelters among stones and aquatic vegetation.
Sounds Ciguatera Speed Swim. Megaleporinus obtusidens Conservation status. 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. 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.
The larger fish probably belong to other species of Leporinus either L. Short description Morphology Morphometrics Dorsal soft rays total: 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.

Metabolic parameters in the liver and muscle lactate, glycogen, glucose, protein, and ammoniaas well as some hematological parameters, were determined.
Curimatus obtusidens Valenciennes, Leporinus silvestrii Boulenger, Leporinus aguapeiensis Amaral Campos, Leporinus obtusidens Valenciennes, These results indicate that AChE activity as well as metabolic and hematological parameters may be good early indicators of herbicide contamination in L.
