Resumo: The white marlin Tetrapturus albidus is a ocean, pelagic and highly migratory specie, exploted by many countries and many commercial, sportive and artisanal fisheries. Like the other bilfishes, they are mainly caught by tunas and swordfish longline fishery, as by-catch, which subject a high fishing pressure. Then, the stock have been over-exploited, although the assessment show several uncertain, because need parameters. Before this, the present work promotes: a description by the fishing operations realized in the capture of white marlin by the leased longline fleet based in northeast Brazil; a distribution and relative abundance analyses and the influence of environmental factors in the capture of the specie; standardized catch and effort rates and reproductive biology information. The statistic tool utilized to standardization of abundance indices (CPUE) and for the analyses of the influence of factors (spatial, temporal and environmental) on the capture and gonad development of white marlin was generalized linear and additive models (GLM and GAM). Year, temperature of sea surface, latitude and depth of local fishing was the factors which more influenced on captures. The pattern of distribution and abundance observed confirms the northsouth migration through the brazilian off shore, of the third to the first trimester. Also was observed that the white marlin follows temperatures strips of about 24°-28°C, and is commonly concentrate in steep drop-offs and interface of different water masses, or in areas with marine richness. The model standardized with GAM showed better adjust than the GLM model, indicating that the inclusion of the factors was significantly in standardization procedure of CPUEs. The catches of white marlinshowed decline for about 15 or 20 years, and some stability since 1999-2000. Size at first sexual maturity (L50) was estimated as 139 cm (low jaw- fork length/ LJFL), for males, and 147 cm, for females. Month and temperature was the factors with more influence on gonad development. The gonad index of white marlin in the Atlantic Equatorial was highest in the end of second and the beginning of the third trimester.

Sua pesca se caracteriza pela grande diversidade de participantes, incluindo pescarias industriais, artesanais e esportivas. No entanto, assim como os demais agulhões, é mais freqüentemente capturado como fauna acompanhante da pesca com espinhel dirigida a atuns e espadarte, sendo sujeitos a uma intensa pressão pesqueira. Como conseqüência, o estoque se encontra sobreexplotado, embora as avaliações apresentem incertezas decorrentes da carência de dados de pesca e informações biológicas.No intuito de contribuir para a superação dessas deficiências, o presente trabalho apresenta: uma descrição das operações de pesca com espinhel pelágico realizadas pela frota arrendada brasileira sediada no Nordeste; uma análise da distribuição e da abundância relativa da espécie e da influência de variáveis ambientais na sua captura; índices padronizados de captura por unidade de esforço, e informações acerca da biologia reprodutiva. Como ferramentas de padronização de índices de abundância (CPUE), bem como das análises de influência de fatores de diversas ordens sobre a captura e o desenvolvimento gonadal do agulhão branco, foram utilizados modelos lineares e aditivos generalizados (GLM e GAM). Ano, temperatura da água do mar, latitude e profundidade do local de pesca foram os fatores que apresentaram maior influência nas capturas. Variações espaciais e sazonais da abundância relativa parecem confirmar a realização de uma migração no sentido norte-sul ao longo da costa brasileira do terceiro para o primeiro trimestre do ano. Osdados indicam, também, que o agulhão branco acompanha preferencialmente a faixa de temperatura de 24°C a 28°C, concentrando-se em áreas de descontinuidades topográficas ou na interface de massas d’água, os quais estão provavelmente associados a fenômenos de enriquecimento. O modelo padronizado por GAM se mostrou mais bem ajustado que por GLM, indicando que a inclusão das variáveis foi significante na padronização das CPUEs. As taxas de captura do agulhão branco apresentam um declínio contínuo ao longo de 15 ou 20 anos, até 1999-2000 passando a exibir, a partir de então, uma maior estabilidade. O comprimento de primeira maturação (L50) foi igual a 139cm de mandíbula inferiorfurca para machos e a 147cm para fêmeas. Mês e temperatura se mostraram os fatores com maior influência sobre o desenvolvimento gonadal. O índice gonadal do agulhão branco na região equatorial do Atlântico foi máximo em torno de maio.Submitted by (edna.saturno@ufrpe.br) on 2017-02-13T15:07:02Z No. of bitstreams: 1 Igor da Mata R P Oliveira.pdf: 2792534 bytes, checksum: 0e4e5664c5eb680f377e167f86443cbf (MD5)Made available in DSpace on 2017-02-13T15:07:02Z (GMT).
