Resumo: The knowledge of embryonic and larvae development of fishes is a fundamental key which enables a closer approach to their biology and taxonomy. The present study aims to characterize piracanjuba (Brycon orbignyanus) embryonic and larvae development. During the whole embryogenesis, 15 to 20 embryos were sampled and analyzed. Eggs of B. orbignyanus are semidense, transparent, spherical, and bear a large perivitelline space. Hatching takes place 18 hours and 30 minutes after fertilization at 25 ± 0.8ºC. Total length and weight of just hatched larvae were 4.46 ± 0.39mm and 2.56 ± 0.73mg, respectively. Larvae presented entirely developed and pigmented eyes, as well as a vertical mouth opening of 15.2 ± 1.9% of body length, 36 hours after hatching, period from which intense cannibalism was observed

O presente estudo teve como objetivo caracterizar o desenvolvimento embrionário e larval da piracanjuba (Brycon orbignyanus). Foram realizadas amostragens contínuas de 15 a 20 embriões durante toda a embriogênese. Os ovos se apresentaram semidensos, transparentes, esféricos e com um grande espaço perivitelínico. Depois de 18 horas e 30 minutos da fertilização, mantidos a 25 ± 0,8°C aconteceu a eclosão. O comprimento total das larvas recém eclodidas foi de 4,46 ± 0,39mm e o peso de 2,56 ± 0,73mg. As larvas de piracanjuba apresentaram forte canibalismo depois de 36 horas da eclosão, quando foi observada também a presença de olhos bem desenvolvidos e pigmentados, assim como uma abertura vertical da boca de 15,2 ± 1,9% do comprimento corporalUniversidade Estadual De Maringá2008-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/166010.4025/actascibiolsci.v26i1.1660Acta Scientiarum.
