Resumo: Male and female pacus (Piaractus mesopotamicus) were induced with broiler chicken (BCPE), rabbit (RPE), and carp (CPE) pituitary extracts. The parameters for spermatic vigor, progressive motility, fertilization and hatching rate, according to semen origin, did not show any differences among the treatments (p > 0.05). RPE produced the lowest (p < 0.05) semen volume and the highest spermatozoa number and concentration (p < 0.05). No difference was observed (p > 0.05) in the total rate of abnormal spermatozoa among the treatments, but the secondary pathologies were higher (p < 0.05) in the treatment with RPE. The females induced with RPE did not present stimulus for hatching. No differences (p > 0.05) between BCPE and CPE were found for accumulated thermal unit, number of oocytes/spawning grams, fertilization and hatchery rates according to treatment origin. The result indicates that BCPE use is recommended for gonadal induction of P. mesopotamicus

Os parâmetros vigor espermático, motilidade progressiva, taxa de fertilização e eclosão de acordo com a origem do sêmen, não apresentou diferença (p > 0,05) entre os tratamentos. O tratamento com BCPE produziu o menor volume de sêmen (p < 0,05), o número e a concentração de espermatozóides foram os mais altos (p < 0,05). Não foi observado diferença (p > 0,05) para o taxa de espermatozóides com anormalidades nos tratamentos, mas as patologias secundárias foram elevadas (p < 0,05) no tratamento com RPE. As fêmeas induzidas com RPE não apresentaram estímulo para a desova. Não houve diferença (p < 0,05) entre BCPE e CPE para a unidade térmica acumulada, número de ovócitos liberados/g de desova, taxa de fertilização e desova de acordo com a origem dos tratamentos.
