Resumo: | The black triggerfish, Melichthys niger, is a fish of family Balistidae, which consists of 11 genera and 40 species. Possessing a coloration ranging from dark blue to black with green metallic reflections, can reach up to 50 cm in total length, with a distribution circumtropical. In this work we examined specimens of black triggerfish , obtained from commercial fishing in the archipelago of Saint Peter and Saint Paul-ASPSP (00 ° 55'02 "N and 29 20'42" W), from January 2006 to May 2008. Soon after capture, specimens were identified and measured, which sent up its total length (TL) and standard (CP). Next, all specimens were dissected to allow the collection of the reproductive system, which were fixed in formalin 10% and was then packed in plastic drums, until their arrival at the laboratory. During the study period, 777 individuals were analyzed, of which 367 were females and 410 were males. Females ranged from 19.0 to 32.0 cm total length, and males from 21.0 to 37.4 cm. From histological analysis was possible that the ovaries of M. niger are composed of ovigerous lamellae containing oocytes at different stages of development. We identified five different stages of oogenesis: young cells, pre-vitellogenic oocytes (perinucleolar) oocytes, cortical alveolar, vitellogenic oocytes and mature oocytes. In addition to the germ cells were also identified some somatic structures composing the ovary: ovary wall, follicular cells and blood vessels. The monthly distribution of maturation stages, from analysis of ovaries indicated a higher frequency of mature females during the first half of the year in the archipelago of Saint Peter and Saint Paul. |

Possuindo uma coloração que vai do azul marinho ao preto, com reflexos verde-metálicos, pode chegar a até 50 cm de comprimento total, apresentando uma distribuição circumtropical. No presente trabalho foram examinados exemplares de cangulo-preto, obtidos a partir da pesca comercial no Arquipélago de São Pedro e São Paulo- ASPSP (00º55'02" N e 29º20'42"W), no período de janeiro de 2006 a maio de 2008. Logo após a captura, os espécimes foram identificados e mensurados, aferindo-se os seus comprimentos total (CT) e padrão (CP). Em seguida, todos os exemplares foram dissecados para permitir a coleta do aparelho reprodutor, os quais foram fixados em solução de formol a 10%, tendo sido, então, acondicionados em bombonas plásticas, até a sua chegada ao laboratório. No período do estudo, foram analisados 777 indivíduos, dos quais 367 eram fêmeas e 410 eram machos. As fêmeas variaram de 19,0 a 32,0 cm de comprimento total, e os machos de 21,0 a 37,4 cm. A partir de análises histológicas foi possível verificar que os ovários de M. niger são formados por lamelas ovígeras contendo ovócitos em diferentes graus de desenvolvimento. Foram identificados cinco diferentes estágios da ovogênese: células jovens, ovócitos pré-vitelogênicos (perinucleolares), ovócitos alvéolo-corticais, ovócitos vitelogênicos, e ovócitos maduros. Além das células germinativas foram também identificadas algumas estruturas somáticas compondo os ovários: parede ovariana, células foliculares e os vasos sanguíneos. A distribuição mensal dos estágios maturacionais, a partir das análises dos ovários, indicou uma maior freqüência de fêmeas maduras durante o primeiro semestre do ano no Arquipélago de São Pedro e São Paulo.Submitted by (edna.saturno@ufrpe.br) on 2017-02-13T15:20:21Z No. of bitstreams: 1 Ilka Siqueira Lima Branco.pdf: 1518380 bytes, checksum: 41e22d5a5fec97fe8faaae6cbde4fa92 (MD5)Made available in DSpace on 2017-02-13T15:20:21Z (GMT).
