Abstract: In order to understand the growth characteristics of juvenile Thamnaconus septentrionalis under industrial aquaculture condition, one month old juvenile Thamnaconus septentrionalis was taken as an experiment sample for cultivation of 9 months under sea water temperature of 11.08℃~26.32℃. The results indicated that: the initial average body weight and average total length of the sample increased from (0.07±0.02)g and (1.59±0.33)cm to (143.20±10.32)g and (20.31±0.67)cm respectively, with the maximum average weight gain of (44.15±5.74)g/month and daily average weight gain of (0.48±0.04)g/d. There was a linear relationship between the total length and age of days: L= 0.0 693 x + 0.3 017 (R2= 0.9468), with the instantaneous growth rate of average total length being 0.008. There was an exponential relationship between body weight and total length, i.e., regression equation: W= 0.014L3.0479 (R2 = 0.996 8), with the power exponent approximate to 3.0, which indicated an isogony; both the first dorsal fin length and body height had a linear relationship with the total length. The growth condition of the experiment sample was greatly influenced by the temperature, with the increment of body weight high at 18.52~26.32℃. The study indicated that Thamnaconus septentrionalis should be cultured in warm water for rapid growth, and presents a promising prospect for development.

摘要： 为探讨绿鳍马面鲀（Thamnaconus septentrionalis）幼鱼在工厂化养殖模式下的生长情况，在海水温度11.08~26.32 ℃条件下，以1月龄绿鳍马面鲀幼鱼为实验样本，进行为期9个月的养殖试验。结果显示，样本初始平均体质量（0.07±0.02）g、平均全长（1.59±0.33）cm增长到（143.20±10.32）g、（20.31±0.67）cm，平均增重量最大值为（44.15±5.74）g/月，平均日增重量（0.48±0.04）g/d；全长与日龄呈线性关系为：L= 0.069 3 x + 0.301 7 （R2 = 0.946 8），平均全长瞬时增长率为0.008；全长与体质量呈指数关系，回归方程式为：W= 0.014L3.0479 （R2 = 0.996 8），幂指数约等于3.0，为等比生长类型，第一背鳍长、体高都与全长呈线性关系；实验样本的生长状况受温度影响较大，在水温18.52~26.32℃时增重较快。研究表明，绿鳍马面鲀适合温水养殖，且生长速度快，有较好的开发前景。
