Mangrove red snapper  Lutjanus argentimaculatus  is a high economically value of snapper. Growth is important biological parameters during larvae stage. The growth of the second generation (F-2) of cultivated  L. argentimaculatus  is important to be evaluated as part of cultivation success. This study was conducted to determine the growth pattern of  L. argentimaculatus  F-2 during larval to juveniles stage. Larval rearing was done in hatchery. Larvae were fed zooplankton rotifers  Brachionus rotundiformis  and  Artemia , also micro pelet as the artificial feed. Microscopic measurement on larval samples were performed periodically every 5 days from 5 to 40 days old larvae, by using 10 larval samples each time. The biological parameters of larvae were total length, standard length, dorsal spine length, ventral spine length, anal spine length and body weight. The results of this study indicated that the growth of mangrove red snapper larvae took place for 35-40 days to metamorphosis become juveniles. The growth pattern on all parameters was exponential. The larval total length has a positive correlation to its body weight with correlation value of 0.99. Larvae had certain characteric growth during metamorphosis stage. Mangrove red snapper  L. argentimaculatus  F-2 had a similar growth pattern with those of larvae F-1.
