Eggs development and early life history of the endangered Korean dwarf loach, Kichulchoia brevifasciata (Teleostei: Cobitidae) was investigated to provide basic information regarding biological characteristics and restoration. Adult fish specimens were sampled using a spoon net at Geurnsan-myeon, Goheung-gun, Jeollanam-do, Korea from June to July 2011. Since, spawning characteristics were analyzed, and females were induced to spawn by injecting Ovaprim (0.5 mL/kg) and their eggs were artificially fertilized with sperms by the dry method in the laboratory. Total length of mature female were 46~76 mm with GSI $9.6{pm}3.77%$, and total length of mature male was 42~52 mm with GSI $3.5{pm}1.04%$. Sex ratio (♂/♀) was 0.10, and there were no secondary sexual characteristics. The number of mature eggs was averaged $60{pm}28.7$ per female. The lemon yellow eggs were slightly adhesive $1.46{pm}0.07mm$ in diameter. The embryo hatched approximately 66 h after fertilization at $25^{circ}C$, and the hatched larvae were averaged $5.5{pm}0.07mm$ in total length (TL). At 6 days after hatching, the larvae averaged $9.0{pm}0.29mm$(TL) and their yolk sac was completely absorbed. At 17 days after hatching, they entered the juvenile stage and reached $12.6{pm}0.24mm$ (TL). At 80 days after hatching, the band patterns and external form of the juveniles were similar to those of adults, and they averaged $33.0{pm}2.19mm$(TL).
