摘要：

Larval duration of the non-native Indo-Pacific lionfish was estimated from samples collected along the Bahamian Archipelago using sagittal otoliths. Settlement marks, characterized by daily growth increments with reduced coloration, less definitive margins, and a re-orientation of the growth axes and otolith shape, were determined for 28 individuals. Settlement age was between 20 and 35 days with a mean of 26.2 days. Comparisons of settlement age to other littoral and reef fish species suggest that lionfish settlement age is moderate to relatively low. Lionfish pelagic larval duration is apparently sufficient to allow their rapid establishment and wide geographic range in the western Atlantic and Caribbean.
