Allometric growth pattern of Percocypris pingi pingi larvae were studied in the laboratory from the day hatched to 57 days. The total length growth rate of larvae changed from slow to fast at the inflexion point of 25 days after hatching (d). Most organisms of larvae exhibited an allometric growth pattern. The growth of head and tail was faster than trunk, and the inflexion point of growth coefficient was at 22-27 d. The inflexion point of growth coefficient of eye diameter occurred at 14-15 d that was earlier than any other organism growth. The inflexion point of growth coefficient of snout length, appeared at 33-34 d; the inflexion point was at 13-14 d, 31-32 d, 32-33 d, 38-39 d and 43-44 d for pectoral fin, dorsal fin, tail fin, anal fin and ventral fin, respectively. Except for pectoral fin and tail fin, the other fins were highly developed at the inflexion point. In the days after hatching at inflexion point of fins, the swimming of larvae was highly improved. The allometric growth pattern of larvae ensured a quickly development of those organisms which have important function to adapt to the complex environment and increase their survival rate. These results may be useful in cultivating fish fry practice and preserving wild resources.
