Otolith analysis allowed backcalculation of size and growth rate at age to examine the relative influences of selective mortality and water temperature on early growth. Negative size-selective mortality and growth-selective mortality between the juvenile and the adult stages was found only in the cohort that was the smallest and slowest growing in the period immediately following hatching. Selective mortality preferentially removed members of this cohort that were smaller from age 0 to 15 days, and slower growing from 0 to 10 days, resulting in an elevation of size at age to, or even above, that of cohorts that had not undergone this process. Size and growth rate at 5 day age intervals in the first 20 days after hatching differed among cohorts within and between summers and were strongly and positively correlated (r(2) = 0.61-0.83) with water temperature. specialized environmental factors Indo-Pacific region life-history traits otolith pelagic fishes size 040 74 4 921-938 2009 0022-1112 https://www.documentation.ird.fr/hor/fdi:010044329 10.1111/j.1095-8649.2009.02179.x 0022-1112 [F B010044329] https://www.documentation.ird.fr/hor/fdi:010044329 https://www.documentation.ird.fr/intranet/publi/2009/03/010044329.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2009-04-08 2017-08-23 fdi:010044329 fre
