Resumo: | Today, the Blue marlin stock is highly overexploited due to the intense fishing effort targeting tunas in the Atlantic Ocean. The blue marlin is an oceanic pelagic and migratory species caught as a tuna bycatch. Although current studies are imprecise, some mitochondrial DNA analysis has shown that there is a single Atlantic blue marlin stock. The present study has the objective to investigate the blue marlin’s reproductive biology, detailing the ovogenesis and characterizing the microscopic maturity stages. The microscopic stages were analyzed through histological cuts stained with hematoxilin/eosin and evaluated under optical microscopy. The MIF length for females ranged from 104 to 345 cm, with a mean of 210 cm. For the males the MIF length ranged from 100 to 267 cm, mean 189 cm. The microscopic maturity scale made for the species is composed of 6 stages for the females and 4 stages for the males. The sexual proportion found is 1.6 males for each female. The mean first maturity size for females was 194.2 cm and for males was 168.6 cm. The spawn type observed was the partial one. The fecundity varied from 2,151,000 and 6,769,060 oocites for females between 272 and 290 cm MIF length. |

O agulhão negro é uma espécie oceânica pelágica, sendo capturada acidentalmente como fauna acompanhante na pesca de atuns com espinhel. As avaliações de estoque realizadas, embora apresentem um grau de incerteza por falta de informações mais detalhadas acerca da sua biologia, levam em consideração a existência de um único estoque de agulhão-negro no Atlântico, como apontam estudos genéticos baseados em análises de DNA mitocondrial. Com o intuito de diminuir tais carências, o presente trabalho tem como objetivo principal investigar a biologia reprodutiva da espécie, detalhando a ovogênese e caracterizando os estágios microscópicos de maturação. A coleta de amostras foi realizada no período de dezembro de 2004 a outubro de 2006, seguida da análise microscópica para a identificação dos estágios maturacionais. O comprimento (MIF) para as fêmeas teve uma amplitude de 104 cm até 345 cm, com uma média de 210 cm. Para os machos, variou de 100 cm a 267 cm, com média de 189 cm. Foram identificados 6 estágios para fêmeas e 4 para machos dentro da escala microscópica confeccionada para a espécie. A proporção sexual de machos e fêmeas foi de 1,6: 1,0. O tamanho médio de 1ª maturação sexual foi estimado em 194,2 cm para as fêmeas e 168,6 cm para os machos. O agulhão negro possui desova parcelada e alta fecundidade, com uma amplitude de 2.151.000 a 6.769.060 ovócitos hidratados.Submitted by (edna.saturno@ufrpe.br) on 2017-02-09T11:51:57Z No. of bitstreams: 1 Carolina Martins Torres da Silva.pdf: 3685448 bytes, checksum: e48d65bdd413ecd20dae68b18bdb4266 (MD5)Made available in DSpace on 2017-02-09T11:51:57Z (GMT).

Today, the Blue marlin stock is highly overexploited due to the intense fishing effort targeting tunas in the Atlantic Ocean. The blue marlin is an oceanic pelagic and migratory species caught as a tuna bycatch. Although current studies are imprecise, some mitochondrial DNA analysis has shown that there is a single Atlantic blue marlin stock. The present study has the objective to investigate the blue marlin’s reproductive biology, detailing the ovogenesis and characterizing the microscopic maturity stages. The microscopic stages were analyzed through histological cuts stained with hematoxilin/eosin and evaluated under optical microscopy. The MIF length for females ranged from 104 to 345 cm, with a mean of 210 cm. For the males the MIF length ranged from 100 to 267 cm, mean 189 cm. The microscopic maturity scale made for the species is composed of 6 stages for the females and 4 stages for the males. The sexual proportion found is 1.6 males for each female. The mean first maturity size for females was 194.2 cm and for males was 168.6 cm. The spawn type observed was the partial one. The fecundity varied from 2,151,000 and 6,769,060 oocites for females between 272 and 290 cm MIF length. |
