Caracterização do desenvolvimento inicial de Auchenipterus osteomystax (Osteichthyes, Auchenipteridae) da bacia do rio Paraná, Brasil. Acta Scientiarum, Maringá, v.23, n.2, p.377-382, 2001.
dc.descriptionThe aim of the present study was to characterize the early development of Auchenipterus osteomystax (Ribeiro, 1918) (Osteichthyes, Auchenipteridae). Specimens were taken from plankton samples in the Upper Paraná river, Ivaí river, Upper Ivinhema river and Itaipu Reservoir. Seventy-four larvae and seven juveniles (with standard length ranging from 5.25 mm to 39.0 mm) were analyzed. Specimens were identified and separated according to their development and morphometric and meristic analyses were performed. The early development of A. osteomystax follows the pattern of other Siluriformes. However, individuals presented more pigmentation on the head and on fore part of the body. Number of myomeres ranged from 44 to 50.
dc.descriptionO objetivo deste trabalho é caracterizar o desenvolvimento inicial de Auchenipterus osteomystax (Ribeiro, 1918) (Osteichthyes, Auchenipteridae). O material analisado é proveniente de amostras coletadas no plâncton no alto rio Paraná, rio Ivaí, alto rio Ivinhema e reservatório de Itaipu. Foram analisadas 74 larvas e 7 juvenis, entre 5,25 mm e 39 mm de comprimento padrão. Os espécimes foram identificados e separados em diferentes estágios, e foram obtidas as variáveis morfométricas e merísticas. As larvas de A. osteomystax apresentam o desenvolvimento inicial semelhante ao de outros Siluriformes, no entanto são caracterizadas principalmente por apresentar um aglomerado de pigmentos na cabeça e na região anterior do corpo e número de miômeros variando de 44 a 50.
