Larvae and juveniles of Saddleback silver-biddy (Gerres limbatus Cuvier, 1830) were collected using a small seine net from the bank waters of the Tien Yen Estuary, Quang Ninh Province, in northern Vietnam. These larvae and juveniles are compressed and relatively slender: Weak spinations are present on the head and on the preoperc1e. Teeth are visible on the tip of the lower jaw. A protractile mouth with a long ascending premaxillary process is observed in the fish. The gut is short and coiled. A small and inconspicuous gas bladder is present above the anterior portion of the gut. The gap between the vent and anal fin is large and decreases with growth. The main counting meristic characters are as follows: D = IX, 10
A = III, 7
P = 13 - 15
24 myomeres. The dorsal profile has four melanophores patches. Morphological comparisons with other congeneric species are also given in the present study.
