The 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 50Downloads
