摘　　要：通过对绿鳍马面鲀早期发育的连续观察,研究绿鳍马面鲀体色的发育过程。结果表明,绿鳍马面鲀仔鱼黑色素和黄色素在胚胎时期发生;虹彩色素在仔鱼3日龄出现,仅限于眼球,预示视觉功能化的完善;处于躯干腹部消化腔上侧浅褐色的色素团在4日龄后分化为黄色素;腹部虹彩色素集中发生在8~10日龄;稚鱼发育至40日龄,躯干部体色主要表现为横向黑色暗纹,属于过度体色模式;200日龄幼鱼,除了偶鳍绿色偏淡外,体色模式与3龄成鱼一致。绿鳍马面鲀体色的形成与形态分布,是判断其早期发育时序的主要特征之一。The morphological characteristics and distributions of chromatophores,together with body color changes during early life history of modest filefish Thamnaconus septentrionalis were observed and photographed.We postulated the larval melanophores and larval xanthophores occurred firstly during embryonesis;iridophores appeared at 3 day post hatching(dph),only on the upper side of eyeball,indicating the perfection of visual function;the larval light brown on the upper side of the digestive cavity of the trunk and abdomen differentiated into larval xanthophores after 4 dph;the iridophores concentrated in the abdominal cavity occurred at 8—10 dph;the body color of the trunk mainly showed transverse black dark lines,belonging to the excessive body color mode pattern in 40 dph juveniles;the sub-adult was similar with adult in the body color pattern,except that the even fin rays color still transparent and little green or blue comparing with the olders at 200 dph.At last,it is conculded that the body color pattern is one of the main characteristics to decide the early life history of modest filefish.
