摘要： Ecological experiment was conducted to study the allometric growth of taimen yolksac 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 body height are growing at a positive allometric speed, the trunk and tail fin length are growing at a slow speed; in the head organs, the rostrum length, eye diameter and head length are growing at a positive allometric speed; in the swimming organs, tail fin length is negative allometric growth; yolk sac length, yolk sac width and yolk sac height are negative allometric growth consumption. The fast development of feeding, breathing, swimming and other organs in yolk-sac larvae of taimen, 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.
