在实验室饲养了2000多个标本，观察了幼虫从孵化到长约10 cm的发育和生长。对幼体和早期幼体的运动时间和游泳速度进行了观察。详细描述了鳍片发育和色素沉着的形态特征。前120天的体长增长用方程Y=2.83+0.15X+0.00247X2表示，其中Y=标准体长(Mm)，X=孵化后的日数。幼体向幼鱼的转变发生在9.0~11.0 mm标准长度(SL)之间。游动速度：仔鱼约1.0SL/S，变态期约2.0SL/S。幼虫向稚鱼转化时，消化道、鳞片、色素花纹和鳍的各种特征发育和分化。文中还讨论了雌雄发生、形态发生和行为在生命早期阶段的意义。
More than 2000 specimens reared in the laboratory were used to observe larval development and growth from hatching to about 10 cm long. Observations of moving time and swimming speed were made for larval and early juvenile stages. Morphological characters of fin development and pigmentation were illustrated in detail. Growth in length was expressed by the equation Y=2.83 +0.15X+0.00247X2 for first 120 days, where Y=standard length in mm and X=days after hatching. Transformation from larvae to juveniles occurred during 9.0 to 11.0 mm standard length (SL). Swimming speed ranged from about 1.0 SL/s for larval stage to 2.0-2.5 SL/s for fish at meta-morphosis. Various characters of digestive tract, squamation and pigment pattern as well as fins developed and differentiated when the larvae transformed to juveniles. The implication of or-ganogenesis, morphogenesis and behavior in the early life stages was discussed.
