Feeding of Hoplias malabaricus in the wetlands of Dulce river (Córdoba, Argentina)
Hydrobiologia, 1995Hoplias malabaricus behaves as a zoophagous and euryphagic species with a strong tendency to eat fish during its entire life. Fish begin to constitute its main food at approximately 200 mm standard length. Insects are important for fish smaller than 50 mm. Crustaceans are of lesser importance for both size groups.

Cytogenetic markers were used to compare the karyotypes of an isolated population of Hoplias malabaricus with others previously described. The results revealed peculiar characteristics that indicate a new independent evolutionary unit within the H. malabaricus complex.

Respiration Physiology, 1999
To determine the location and distribution of chemoreceptors involved in the cardiovascular and respiratory responses to hypoxia of traira (Hoplias malabaricus), we measured heart rate, arterial blood pressure, ventilation frequency and amplitude of opercular movements during exposure to hypoxia and application of NaCN to either water bathing the gills

Henneguya malabarica sp. nov. (Myxozoa, Myxobolidae) in the Amazonian fish Hoplias malabaricus
Parasitology Research, 1996Henneguya malabarica sp. nov. is described from the Amazonian teleost fish Hoplias malabaricus Boch, 1794, collected from the estuarine region of the Amazon river near Belém, Brazil. Plasmodia were represented by several vegetative nuclei, generative cells, and sporogony stages contained in cyst-like plasmodia.

Contracaecum sp. infection in Hoplias malabaricus (moncholo) from rivers and marshes of Colombia
Veterinary Parasitology, 2006Nematode infection indices were recorded in Hoplias malabaricus captured in six different rivers and a marsh belonging to the North Coast Basin of Colombia, and from the Amazon River, during February 2003-December 2004. Preliminary morphological analysis of nematodes indicated the presence of Contracaecum sp.

Morphological and Molecular Alterations in the Gonads of
ABSTRACT Mining is one of the most important activities in the economic development of several countries; however, it generates significant impacts on water resources, releasing metals in these environments. The exposure of fish to metals alters the redox capacity of the organism, increasing the production of ...

Modulatory effect of nano TiO₂on Pb in Hoplias malabaricus trophically exposed.
Environmental toxicology and pharmacology, 2015This study investigated the hepatic and neural effects of TiO₂ nanoparticle and Pb in Hoplias malabaricus trophically exposed. The alanine transaminase activity was altered at the high dose of exposed group to Pb and at the lowest doses of co-exposed groups.
