Abstract: To enrich the basic biology information of E. moara， morphological features of early development stage of the fish was observed and described with ecological habit of different stages. Also， the changes of total length， oral fissure， the 2nd dorsal fin spine and the pelvic fin spine were recorded in detail. The post embryonic development of E. moara is divided into stages of early larva and late larva， of juvenile and of young fish according to the changes of the yolk sac， fin membrane， the 2nd dorsal fin spine， the pelvic fin spine， scales， and pigment of the fish. It is found that larva start to feed after age of 4 days in condition of water temperature 26.71±1.26℃. After 6 days， the yolk sac and oil ball of the larva absorb and disappear， then the larva develope into late larvae stage. After 29 days， fin membrane of fish disappears and fish develops into juvenile stage. After 41 days， scales appear on the fish body. After 59 days， the whole body of fish has covered with scales， completing the metamorphosis and developing into young fish stage. In addition， we also found that raising the cultivation temperature in the ecological amplitude could improve the growth efficiency， and speed up the seedling of E. moara．
