Resumo: The study presents information about the reproductive characterísticas of bigeye tuna (Thunnus Obesus0. Were obtained 1082 samples of this species in the tropical Western Atlantic between July of 2004 and June of 2006. Were realized 873 (522 females and 351 males) histological cuts and observations of the present oocytes, analyzed with microscopy to determine the stage of gonadal development. For the females were determined 5 maturational stages: immature, initial and advanced maturation, spawning and resting. The fork length of the samples varied from 62 to 210 cm, and the sexual ratio was 1.46:1 (female:male). The females of bigeye tuna with high values of Gonadossomatic Index associated with advanced maturation were found during the first trimester, suggesting that this species has bigger reproductive activity in this period.The L for females was 92.8 cm and the males 82.1 cm. The estimate mean fecundity through hydrated oocytes counting for this species was 3,971,328 oocytes.

Para isso, foi obtido um total de 1082 amostras de gônadas da presente espécie no Atlântico oeste Tropical entre julho de 2004 e junho de 2006. foram realizados 873 (522 fêmeas r 351 machos) cortes histológicos e observações dos ovócitos presentes, analisados microscopicamente para determinação das fases de desenvolvimento gonadal. Para as fêmeas foram determinados 5 estágios maturacionais: maturo, maturação inicial e avançada, desovado e em repouso. O comprimento zoológico dos exemplares variou de 62 210 cm, e a proporção sexual foi de 1,46 fêmeas para um macho. A relação entre o Índice Gonadal e exemplares em maturação avançada mostrou que a albacora bamdolim parece possuir maior atividade reprodutiva no primeiro trimestre do ano. O tamanho de primeira maturação sexual para as fêmeas foi de 92,8 cm, já para os machos esse valor foi menos, 82,1 cm. A fecundidade média estimada através da contagem de ovócitos hidratados para a presente espécie foi de 3.971.328,13 ovócitos.Submitted by (edna.saturno@ufrpe.br) on 2017-02-16T14:56:11Z No. of bitstreams: 1 Marina Bezerra Figueiredo.pdf: 4281028 bytes, checksum: 769a66f89e02f5c1359899b741605fea (MD5)Made available in DSpace on 2017-02-16T14:56:11Z (GMT).
