Estudio Histológico del Tracto Digestivo del Neón Cardenal Paracheirodon axelrodi (Characidae) [PDF]
International Journal of Morphology, 2011 Paracheirodon axelrodi es el pez ornamental que mas se exporta en Colombia. Sin embargo, se desconocen varios aspectos de su biologia basica. Se estudio la histologia del tracto digestivo. Se sacrificaron 15 ejemplares (MS 222, 0,5 g/L), fijados en formaldehido al 4 % y decalcificados con acido nitrico 7 %. Se siguio el procedimiento para H&E.

Aquatic Toxicology, 2016 Copper at high concentrations is an ionoregulatory toxicant in fish and its toxicity is known to be strongly modulated by the water chemistry. The toxicity of Cu to the tropical fish cardinal tetra (Paracheirodon axelrodi) was investigated in waters from two major rivers of the Amazon watershed: the Rio Negro (filtered

Water Research, 2017 This study investigated the acute toxicity of nickel (Ni) to cardinal tetra (Paracheirodon axelrodi), within the three main water types of the Amazon basin: black (Rio Negro), white (Rio Solimões) and clear (Rio Tapajós) during the wet and dry season at pH 7 (representative of white and clear rivers) and pH 4 (representative of black waters).

Parasitology Research, 2016
An investigation of mortalities in a group of cardinal tetras Paracheirodon axelrodi Meyers, 1936, a popular ornamental fish, revealed myxozoan parasites in ventricles of the brains in 3/10 fish and the ocular retina of a fourth. Parasite impacts were unclear, as additional histopathological findings were present, including bacterial dermatitis and ...

Temperature is the main factor affecting the distribution of the sympatric Amazon fishes Paracheirodon axelrodi and Paracheirodon simulans. Both species are associated with flooded areas of the Negro river basin; P. axelrodi inhabits waters that do not exceed 30°C, and P. simulans lives at temperatures that can surpass 35°C.
