摘　　要：目的研究室内人工繁育诸氏鲻虾虎鱼的形态与生长特性，为其开发应用积累生物学资料。方法室内恒温（24℃～26℃）培育诸氏鲻虾虎鱼，采用SPSS软件分析其形态、生长特征参数。结果雌雄诸氏鲻虾虎鱼体长／头长、头长／眼径、头长／尾柄长、头长／尾柄高4项比例性状差异显著；全长、体长、体质量与日龄的关系式分别为LT=5.2×10-7t30．0007tz＋0．2583t＋0．5666（R2=0．995）、LB=4．6×10-7t3—0．0006t0＋0．2239t＋0．477（R2=0．993）、WB=-8．0×10’t3—0．0002t0＋1．7226t．63．732（R2=0．997）；体长与体质量的关系式为W=0．0136LB3.1103（R2=0．977）；Bertalanffy模型也可较好拟合诸氏鲻虾虎鱼的全长、体质量与日龄关系，拟合曲线分别为：Lt=37．5×（1-0．6e-0.012t）3；Wt=775．7×（1-1．68e-0.08t）3；诸氏鲻虾虎鱼的肥满度随个体生长而逐渐升高；雄鱼生长较快。结论诸氏鲻虾虎鱼全长、体长和体质量的日增长率呈下降趋势；全长、体长的日均增长量在仔、稚鱼期逐渐增加，其后增速减慢；体质量的日均增长量从幼鱼期至成鱼期逐渐增加，250日龄后则呈下降趋势：个体生长差异较小。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 morphol- ogy 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 wasLT=5.2×10-7t30.0007tz＋0.2583t＋0.5666（R2=0.995）、LB=4.6×10-7t3-0.0006t0＋0.2239t＋0.477（R2=0.993）、WB=-8.0×10＇t3-0.0002t0＋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 wereLt=37.5×（1-0.6e-0.012t）3;Wt=775.7×（1-1.68e-0.08t）, 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.
