Abstract

Fish collected at settlement ranged in age from 37-78 d, yet size only ranged from 12.7-16.0 mm. Examination of otolith increment width, used as measure of daily growth, revealed 2 patterns: 1) fish with long larval lives (eg 50-78 d) had an abrupt slowing of growth after 35-37 d in the plankton, with continued slow growth until settlement; and 2) fish that settled early (eg 35-40 d) had no evidence of slow growth. Constraints on the larvae to delay metamorphosis may be related to the need to find a suitable settlements site within the appropriate stage of their development. -from Author
