Resumo: | Since the 50’s, Xiphias gladius (Linnaeus, 1758) has been captured along the Brazilian coast by surface longliners. This is the second most important target species for the tuna fleet based in Itajaí, Santa Catarina State, after the blue-shark, Prionace glauca (Linnaeus, 1758). The study was based on data from sea observers, log books and carcass ladings of Xiphias gladius, Linnaeus, 1758) from the pelagic longline fleet based in Itajaí, which operated in the southwest Atlantic. Covariance models were fit to the catches (weight, kg) of swordfish and the effects used were: (1) the years 1997, 1998, 2001, 2002 e 2007 (2) lunar phases and (3) seasons. The covariate was fishing effort (hooks). The highest moon catches occurred on the first quarter moon and during wintertime. The Mantel-Haenszel procedure was used to test the hook selectivity and showed that the type “J” hook (J 9/0 10º offset), traditionally used by the fleet, have 1.2 more chances of catching Xiphias gladius than the “circle” hook (18/0 10º offset), used as an optinal device to reduce sea turtle bycatch. The M-H test showed that the J hook has 1,2 more chances of catching Xiphias gladius than the circle hook. The conversion of individual carcass weights (kg) to total length (cm) for the years 2000 to 2002 showed that 66% of the catches were sub-adults. |

Esta é a segunda mais importante espécie-alvo da frota atuneira sediada em Itajaí (SC), ficando atrás apenas do tubarão-azul, Prionace glauca (Linnaeus, 1758). No presente estudo foram analisados os dados obtidos para esta espécie através de observadores, mapas de bordo e fichas de desembarque de carcaças de X. gladius para a frota de espinhel-de-superfície sediada em Itajaí (SC) e atuante no Atlântico sudoeste. Foram elaborados modelos de análise de covariância (ANCOVA) e aplicados aos dados de captura (peso em kg) do espadarte, tendo como efeitos: (1) os anos de 1997, 1998, 2001, 2002 e 2007 (2) as fases lunares e (3) as épocas do ano. A covariável foi o esforço de pesca (n° de anzóis). As maiores médias de captura ocorreram durante as fases de lua crescente e no inverno. O procedimento estatístico de Mantel-Haenszel teste foi utilizado para comparar as capturas do espadarte no anzol tipo “Jota” (9/0 10º offset) comumente utilizado pela frota espinheleira com o anzol tipo “circular” (18/0 10ºoffset), este último oferecido como alternativa mitigadora à captura de tartarugas marinhas. O teste M-H indicou que o anzol “Jota” apresentou 1,2 mais chances de capturar Xiphias gladius que no “circular”. A conversão dos pesos individuais das carcaças (kg) em comprimentos totais (cm), referentes aos anos de 2000 a 2002, indicou que 66% das capturas foram de sub-adultos, ao longo de todo o ano.Submitted by (edna.saturno@ufrpe.br) on 2017-02-07T12:40:31Z No. of bitstreams: 1 Ana Lia Camposa Quaggio.pdf: 1430515 bytes, checksum: 68e33f51877fa5eba2d7e0997b3e6520 (MD5)Made available in DSpace on 2017-02-07T12:40:31Z (GMT).
