A continental-wide molecular approach unraveling mtDNA diversity and geographic distribution of the Neotropical genus Hoplias. [PDF]
PLoS ONE, 2018 With an estimate of around 9,000 species, the Neotropical region hosts the greatest diversity of freshwater fishes of the world. Genetic surveys have the potential to unravel isolated and unique lineages and may result in the identification of ...

Avaliação de canibalismo e comportamento territorial de alevinos de trairão (Hoplias lacerdae)
Acta Scientiarum: Biological Sciences, 2008 Com o objetivo de avaliar o comportamento territorial e de canibalismo, alevinos de trairão foram medidos e separados, de acordo com o comprimento em cinco classes: I (11,16 ± 0,68 cm), II (8,66 ± 0,60 cm), III (6,33 ± 0,60 cm), IV (4,60 ± 0,12 cm) e V ...

Níveis de arraçoamento para juvenis de trairão (Hoplias lacerdae) [PDF]
Revista Brasileira De Zootecnia, 2008 Com esta pesquisa buscou-se avaliar diferentes níveis de arraçoamento, em porcentagem de peso corporal (PC), para juvenis de trairão em início do período de engorda. Peixes com comprimento de 15,0 ± 1,0 cm e peso de 38,5 ± 8,2 g foram distribuídos em seis aquários com 250 litros de água cada, em densidade de cinco juvenis/aquário.

Evolutionary cytogenetics of the Hoplias lacerdae, Miranda Ribeiro, 1908 group: a particular pathway concerning the other Erythrinidae fish [PDF]
Brazilian Journal of Biology, 2007 The taxonomy/systematics of the Erythrinidae fish is still imprecise, with several doubts on their relationships. Karyotypes and chromosomal characteristics of some species of the Hoplias lacerdae group (Erythrinidae), from different Brazilian hydrographic basins and pisciculture stations, were analyzed in the present study, using conventional Giemsa ...

Anatomy of the buccopharyngeal cavity of trairão, Hoplias Lacerdae Miranda Ribeiro, 1908 (Characiformes, Erythrinidae) [PDF]
Biotemas, 2009 We studied the buccopharyngeal cavity anatomy of 20 male and female trairão, Hoplias lacerdae (Miranda Ribeiro, 1908) specimens, with 24.41cm average standard-length, fixed in 4% formalin aqueous solution and/or diaphanized and colored with alizarin and ...

Comparative Biochemistry and Physiology Part A, Molecular & Integrative Physiology, 2009 The localization, distribution and orientation of O(2) chemoreceptors associated with the control of cardio-respiratory responses were investigated in the neotropical, Hoplias lacerdae. Selective denervation of the cranial nerves (IX and X) was combined with chemical stimulation (NaCN) to characterize the gill O(2) chemoreceptors, and the fish were ...
