Resumo: | Biological and fishing data of bigeye, Thunnus obesus (Lowe, 1939), caught by longliners based Santos, São Paulo State, Brazil and operating off the Brazilian Southeast-Southern coast from 1977 to 1995 were analyzed. It was verified a decrease on the capture of this species due to technological aspects and the interest in other species. The monofilament longline, in use since 1994, proved to be more efficient than the traditional longline. Young fish were caught mainly in the first half of year. A high frequency of individuals smaller than 80 cm was observed in January and February. The highest catches happened from April to September, period in which the adults prevail. There was a reduction in the medium weight (about 50%) of the fishe captured in the period 1969-95. In spite of that decrease, the medium weight of the specimens captured by the longliner fleet settled in Santos was slightly higher than the one observed in the 1990‘s for the oriental longliner fleets operating in the Atlantic |

Verificouse tendência de declínio na captura, devido a fatores tecnológicos e ao direcionamento da pesca para outras espécies. O espinhel superficial, utilizado a partir de 1994, mostrou-se muito mais eficiente que o espinhel tradicional. Exemplares jovens foram capturados principalmente no primeiro semestre. Nos meses de janeiro e fevereiro observou-se uma maior freqüência de indivíduos menores que 80 cm. As maiores capturas ocorreram de abril a setembro, período em que predominam os adultos. Houve uma redução ao redor de 50% no peso médio dos exemplares capturados no período 1969-95. Apesar dessa diminuição, o peso médio dos exemplares capturados pela frota atuneira sediada em Santos foi, na década de 90, ligeiramente superior ao dos exemplares pescados pelas frotas atuneiras orientais em atividade no Atlântico.Arquivo de Ciências do Mar2020-10-05T12:46:10Z2020-10-05T12:46:10Z2000info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfFAGUNDES, Lúcio; ARFELLI, Carlos Alberto; AMORIM, Alberto Ferreira de.
