Resumo: This study aimed to analyze the morphometry of hybrids’ eggs under stereomicroscopy. The induced reproduction was carried out in specimens of pintado’s females (P. corruscans) and cachara’s males (P. fasciatum) from Cepta - Ibama, Pirassununga, state of São Paulo, Brazil. Samples were collected in extrusion moment, during the fertilization, in times of 10 and 30 seconds, 1, 2, 5, 8, 10, 15, 20, 30 and 45 minutes, 1 hour, at every 15 minutes until completing 2 hours, and afterwards, at every hour until the larval hatching. Oocytes and eggs’ external morphology were observed, photographed and 30 samples from each moment were measured in stereomicroscopy. Oocytes, in the time of extrusion, and the eggs presented a spherical form and yellowish color. Characteristics such as wide perivitelinic space, somites, presence of optical vesicle and the main phases of embryonic development as egg-cell (blastodisc), 2, 4, 8, 16, 32 and 64 blastomeres, morula, blastula, gastrula, epiboly movements, formation and larvae hatching were verified.

Foi realizada a reprodução induzida em exemplares de fêmeas de pintado (P. corruscans) e de machos de cachara (P. fasciatum) do Cepta - Ibama, Pirassununga, Estado de São Paulo, Brasil. As amostras foram coletadas no momento da extrusão, durante a fertilização, nos tempos 10 e 30 segundos, 1, 2, 5, 8, 10, 15, 20, 30 e 45 minutos, 1 hora, a cada 15 minutos até completar 2 horas e depois a cada hora até a eclosão da larva. Ovócitos e ovos foram observados quanto à morfologia externa, fotografados e 30 amostras de cada momento foram medidas em estereomicroscópio. Os ovócitos, no momento da extrusão, e os ovos apresentaram formato esférico e coloração amarelada. As características observadas foram: amplo espaço perivitelínico, somitos, presença da vesícula. As principais fases do desenvolvimento embrionário como célula-ovo (blastodisco), 2, 4, 8, 16, 32 e 64 blastômeros, mórula, blástula, gástrula e eclosão da larva também foram verificadasUniversidade Estadual De Maringá2007-11-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/12610.4025/actascibiolsci.v29i1.126Acta Scientiarum.
