Abstract: Objective To accumulate biology data for experimental development of Mugilogobius chulae, the morphology and growth characteristics of housing and propagation of M. chulae were studied. Methods M. chulae were cultivated under constant temperature (24℃~26℃), the morphology and growth characteristics in various developing stages were measured and analyzed by SPSS software. Results There were significant differences between male and female in the ratio of standard length to head length, head length to eye diameter, head length to caudal peduncle length, and head length to caudal peduncle depth. The relation formula between total length, standard length, body weight and age of day was L_T =5.2×10^-7t³ -0.0007t²+0.2583t+0.5666 (R²=0.995), LB =4.6×10^-7t³-0.0006t²+0.2239t+0.477(R²=0.993) and WB=-8.0×10^-7t³-0.0002t²+1.7226t-63.732 (R2=0.997) respectively. The relation formula between standard length and body weight was W=0.0136LB3.1103 (R2=0.977). The Von Bertalanffy growth equations of total length (LT), weight (WT) and age of day were L_T=37.5×(1-0.6e^-0.012t)³, W_T=775.7×(1-1.68e^-0.08t)³, respectively. The condition factor of M. chulae was continuously increasing with individual growth and the male was grown faster than the female. Conclusions The increase rate of total length, body length and weight of M. chulae were showed tendency to descend with age. Average daily increase of total length and body length were ascended during larvae and juvenile stages, and then it was slowed down. The average daily increase of body weight was increased faster in early period but slower after 250-day-old. The individual difference of growth of M. chulae was not significant.
