摘要： Ecological experiment was conducted to study the allometry of fine scale fish yolk-sac larvae and its significance in adaptation in early life stage. The results indicated organs such as feeding, breathing and swimming of larvae in the yolk sac stage are rapidly differentiated, and all key organs are allomorphic. In all parts of the body, the head length and tail fin length are growing at an allometric speed, the trunk is growing at a slow speed, and the body height is isokinetic growth; in the head organs, the rostrum length and head length are growing at a positive allometric speed; in the swimming organs, tail fin length is positive allometric growth; yolk sac width and yolk sac height are positive allometry consumption. The fast development of feeding, breathing, swimming and other organs in yolk-sac larvae of fine scale fish, increases larval survival ability at the early stage in the shortest possible time, and there were important ecological significance to adapt the complex and changing external environment.
