Resumo: This study investigated the fecundity and spawning type of electric fish Electrophorus electricus of the Environmental Protection Area - APA Curiaú River, Amapá - Macapá. The analyzes were performed from 96 samples of fish collected from March 2006 to February 2007. Analysis of the annual cycle of gonadal maturation stages, macro and microscopic examinations of the gonads, verification and counting of the diameters of oocytes were performed. The number of oocytes is related to a body dimension (length)and the Total Weight (g) was adjusted to a linear regression. The results revealed that spawning is complete and synchronous type, occurring in early winter (January-February). Fecundity, estimated ranged from 1730 to 3063 vitellogenic oocytes. The fecundity was positively correlated with the total length and total body weight, increasing proportionally with the size of Electrophorus electricus.Keywords: reproductive biology; Amapá; maturation stages; Brazil.

As análises foram realizadas a partir de 96 exemplares do peixe coletados no período de março de 2006 a fevereiro de 2007. Análises do ciclo anual de estádios de maturação gonadal, exames macro e microscópico das gônadas, verificação dos diâmetros e contagens dos ovócitos foram realizadas. O número de ovócitos relacionados a uma dimensão corpórea (comprimento total) e ao Peso Total (g) foi ajustado a uma regressão linear. Os resultados revelaram que a desova é do tipo total e sincrônico, ocorrendo no início do inverno (janeiro-fevereiro). A fecundidade, estimada variou de 1.730 a 3.063 ovócitos vitelogênicos. A fecundidade mostrou correlação positiva com o comprimento total e peso total do corpo, aumentando proporcionalmente com o tamanho de Electrophorus electricus.Palavras-chave:biologia reprodutiva, Amapá, estádios de maturação gonadal, Brasil.Universidade Federal do AmapáSá-Oliveira, Júlio CésarMendes-Jr, Raimundo Nonato Gomes2012-07-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Avaliado pelos Paresapplication/pdfhttps://periodicos.unifap.br/index.php/biota/article/view/43310.18561/2179-5746/biotaamazonia.v2n1p32-36Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota); v. 2, n. 1 (2012); 32-362179-5746reponame:Biota Amazôniainstname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPporhttps://periodicos.unifap.br/index.php/biota/article/view/433/v2n1p32-36.pdfhttps://periodicos.unifap.br/index.php/biota/article/downloadSuppFile/433/56biologia reprodutiva, Amapá; estádios de maturação gonadal; Brasil.Direitos autorais 2012 Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2016-04-18T20:33:22Zoai:ojs.pkp.sfu.ca:article/433Revistahttp://periodicos.unifap.br/index.php/biotaONGhttps://periodicos.unifap.br/index.php/biota/oai||juliosa@unifap.br2179-57462179-5746opendoar:2016-04-18T20:33:22Biota Amazônia - Universidade Federal do Amapá (UNIFAP)false
