Resumo: | We studied the reproductive biology of Astyanax scabripinnis by monitoring oocyte development of 94 adult females. Microscopic analysis of the ovaries, gonadosomatic and hepatosomatic indeces assessment, visceral fat and condition factor evaluations were carried out. The structures observed in the ovaries were described from the histological analysis and the hepatosomatic índex, which were used to determine the involvement of the liver in the development of oocytes of this species. Oogonia, oocyte I and oocyte II were present in all stages of gonadal development. Oocytes with cortical vesicles were present in large quantities in the intermediate stage of maturation (F2B) and in a lesser amount in the final stages of maturation (F2C). Mature oocytes were common in the intermediate stage of maturation (F2B), but prevailed in the final stages of maturation (F2C). Oocytes in final maturation and mature viable oocytes, many atresic and post-ovulation folicles were found in spawned animals, besides the ovary disorganization, which are strong characteristics of spawing. Spawned animals were found throughout the year, showing that the species presents a kind of intermittent spawning.KEYWORDS: liver, oocyte; reproduction. |

Foram feitas análises microscópicas dos ovários e dos índices gonadossomático, hepatossomático, de gordura visceral e fator de condição. As estruturas observadas nos ovários foram descritas a partir da análise histológica que, juntamente com o hepatossomático, foram utilizadas para determinar a participação do fígado no desenvolvimento dos ovócitos desta espécie. Ovogônias, ovócito tipo I e ovócito tipo II estiveram presentes em todos os estádios de desenvolvimento gonadal. O ovócito que apresentou vesícula cortical esteve presente em grande quantidade no estádio intermediário de maturação (F2B) e em menor quantidade na fase final de maturação (F2C). Ovócitos maduros foram comuns no estádio intermediário de maturação (F2B), mas prevaleceram na fase final de maturação (F2C). Em animais desovados foram encontrados ovócitos em maturação final e maduros viáveis, muitos folículos atrésicos e pós-ovulatórios, além de desorganização do ovário, características definitivas da ocorrência de desova. Foram encontrados animais desovados por todo o ano, evidenciando que seja uma espécie de desova parcelada.PALAVRAS-CHAVE: fígado; ovócitos; reprodução.Universidade Federal de Goiás2011-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/220210.5216/cab.v12i4.2202Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 12 No. 4 (2011); 625-634Ciência Animal Brasileira / Brazilian Animal Science; v. 12 n. 4 (2011); 625-6341809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/2202/10026https://revistas.ufg.br/vet/article/view/2202/10027Pereira Filho, Hélio Paulode Andrade, Dalcio RicardoTonini, William Cristiane TelesVidal Junior, Manuel Vazquezinfo:eu-repo/semantics/openAccess2012-01-30T12:21:40Zoai:ojs.revistas.ufg.br:article/2202Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:00.256862Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
