Abstract:The body color variation and fins development at early life stages of mullet(Liza haematocheila) were continually observed by colleting samples of larvae,juveniles and young fish reared in pond from newly hatching to 39 days after hatching. It turn out that the newly hatched larvae fish does not have melanin, just that the yolk sac with melanoma, two days after hatching surface increased melanin, fin membrane colorless and transparent. 8 dph-day-old larvae had become opaque, black line ventral spots. In the 18-19 dph old-age,larvae transformed into juveniles, the fish back with a lot of snow-like melanin granules in the shade under transparent yellowish spots, 30 dph-day-old juvenile similar to adult fish about the surface with a pale white, brown back belly white.The developmental sequence of the fin in the early developmental stages of larval Liza haematocheila is: pectoral fin, caudal, ventral, dorsal, anal, and the second fin spines. Newly hatched larvae, finfold from edge of the head, the tail back to bypass and ends at the rear edge of the yolk sac, lateral oil balls. 2 dph-day-old larvae with a pectoral fin buds, densely fin membrane at all body, 5 dph-day-old larvae had pectoral and caudal fins film.It had considerable athletic ability, and can play a catalytic role in maintaining body balance. During early development of fins the most obvious change is the growth and development of caudal fin sections. Liza haematocheila larvae had appeared pelvic spines bud base at 12 dph days of age, while the second dorsal fin spines appear at 15 dph. 17 dph: tailbone bent upward, basically developed, long fin 16, with 10, the end of the middle section a few spines has two to three bifurcation, short fin root has 6-8 up and down . Dorsal fin with 11 rays, with five outer most spiny fin spines, the base of support fin bones. To 30 dph, young Liza haematocheila’s fins have fully developed, similar to the adult fish.
