Resumo: The aim of this study was to characterize the early development of Hoplias aff. malabaricus. The sampling was conducted during the period from November 1991 through February 1995, at 42 stations distributed in different environments of the upper Paraná river floodplain, Brazil. The specimens were taken from limnetic and littoral regions. Specimens were separated according to their development in larval (preflexion, flexion and postflexion stages) and juvenile periods. Morphometric and meristic variables were analyzed in 269 larvae and 74 juveniles (standard length ranging from 6.17 mm to 49.12 mm). Larvae showed fusiform body and intense pigmentation, a long intestine, large eyes and terminal mouth. Number of myomeres ranged from 37 to 45 (23-28 pre and 11-18 post-anal). The juveniles presented a body shape similar to their adults. The numbers of fin rays were: pectoral, 12; pelvic, 7-9; dorsal, 13-15; and anal, 10-12. Analysis of the growth showed metamorphosis in the early development of this species.

As amostragens foram realizadas entre novembro de 1991 e fevereiro de 1995, em 42 estações de coleta, distribuídas em vários ambientes da planície alagável do alto rio Paraná, Brasil. Para a obtenção do material, foram realizadas amostragens nas regiões pelágica (rede de plâncton) e litorânea (“peneirão”). Para a caracterização das diferentes fases, os indivíduos foram separados em períodos larval (estágios de pré-flexão, flexão e pós-flexão) e juvenil. Foram analisadas as variáveis morfométricas e merísticas em 269 larvas e 74 juvenis, com comprimento padrão variando entre 6,17 e 49,12 mm. As larvas apresentaram corpo fusiforme e altamente pigmentado, olhos grandes, intestino longo e boca terminal. O número total de miômeros variou de 37 a 45 (23 a 28 pré e 11 a 18 pós-anal). Os juvenis apresentaram a forma do corpo semelhante a do adulto. O número de raios das nadadeiras encontrado para a espécie foi: peitoral 12; pélvica 7-9; dorsal 13-15; e anal 10-12. A análise do crescimento indicou a metamorfose no início do desenvolvimento desta espécie.Universidade Estadual De Maringá2008-05-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/360810.4025/actascibiolsci.v30i2.3608Acta Scientiarum.
