Abstract: ABSTRACT. Larval development of Brycon hilarii (Characiformes, Characidae). The present study characterizes the early stages of development of Brycon hilarii (Valenciennes, 1850) based on morphometric and meristic characters. Patterns of development in morphometric characters were analyzed through the fit of linear, quadratic and linear piecewise models. Samples were collected from March 2000 to March 2004 in basins of the Cuiabá and Manso rivers, state of Mato Grosso, Brazil. Larvae were identified and classi… Show more

“…The rapid embryonic development (14 h at an average temperature of 28.2 ºC) of P. reticulatum in the present study can also be observed in species using the same reproductive strategy (long-distance migratory species). This rapid embryonic development may allow longer survival, as the species does not have parental care (Oliveira et al, 2012). Pérez et al (2001) reported 14 h of incubation at a temperature of 27 ºC, corroborating the present study.…”

“…Characterizing the shape and distribution of pigmentation is also widely used in taxonomic studies to identify larvae and juveniles (Nascimento & Araújo-Lima, 1993;Meijide & Guerrero, 2000;Godinho, Santos, & Sato, 2003;Oliveira et al, 2012). In the cichlids A. ocellatus (Nakatani et al, 2001;Paes et al, 2011), O. niloticus (Nakatani et al, 2001;Fujimura & Okada, 2007), C. nigroasciatum (Martinez & Murillo, 1987), H. nicaraguensis (Molina, 2011) and S. pappaterra, the presence of dendritic pigments in the upper region of the head at the onset of the larval period appears to be a common trait.…”

“…This difficulty stems largely from the significant morphological similarities between different taxonomic groups during early stages of development (Bialetzki, Sanches, Baumgartner, & Nakatani, 1998) and because species spawn in the same areas at the same times of the year (Nakatani et al, 2001). Hence, the taxonomic characterization of early fish development could help us to better understand the ecological relationships between species during development within their natural environments, which could yield tools for more effective environmental assessments (Oliveira, Bialetzki, Gomes, Santin, & Taguti, 2012).…”
