As tripulações de navios atuneiros marcaram e mediram 731 tartarugas-caretas (Caretta caretta) durante as safras de 1990, 1991 e 1992. Os comprimentos curvos das carapaças das tartarugas variaram de 10 a 82 cm. A distribuição interanual de tamanhos não foi significativamente diferente. O tamanho médio de 45 tartarugas marcadas na Madeira foi significativamente maior do que o das tartarugas dos Açores. Os resultados deste trabalho suportam a hipótese de as pequenas tartarugas pelágicas desta espécie derivarem da população reprodutora existente no Sudeste dos E.U.A. O espectro de tamanhos de tartarugas-caretas que vivem nas águas envolventes dos Açores foi aumentado.
ABSTRACT: Crews from commercial tuna vessels tagged and measured 731 loggerhead sea turtles (Caretta caretta) during the 1990, 1991, and 1992 fishing seasons. Turtles ranged in size from 10 to 82 cm curved carapace length. The size distributions among years were not significantly different. The mean size of 45 loggerheads tagged in Madeira was significantly larger than that of Azores turtles. Results of this work support the hypothesis that small, pelagic loggerheads in the eastern Atlantic are derived from the breeding population in the south eastern U. S. The size range of loggerheads known to inhabit waters around the Azores has been expanded.
