摘要: Carapace length growth data were obtained from 197 hawksbill turtles Eretmochelys imbricata which marked and recaptured 1992 to 2000 at feeding grounds of Mona Monito Islands, Puerto Rico. Straight-line carapace (SCL) upon initial capture ranged 20.0 84.5 cm. SCL rates -0.59 9.08 cm yr -1 , non-monotonic, aver- aged highest in measuring 34 35 Somatic varied by site within the study area, with aggregation Island growing on average 2.1 times faster than res- idents habitats. Aggregation density body condition index (body mass -3 ) also Island. Hawksbills recruiting 23 are expected reach maturity less 14.7 later. Growth studied similar those reported for other Caribbean localities, but hawksbills southern Great Barrier Reef, Australia. appear capable utilizing habitats widely varying quality, prey abun- dance exerting a strong effect somatic rates.
